I'm slow
Okay, it took a week, but I've finally included the link for the
Bios guide over at 3D
Spotlight. I'm officially stupid. -Rat
Blurbage
New
board...great work Rat.
Speed is noticeably faster and comments have been very favourable,
homage due. As for the money ($200) for a registration to allow full
implementation of all its bells and whistles several people have
pledged funds. Together with zAmboni's
recent stats improvements I think this house is on a winner. Roelof
has been claiming there will be an update to Setispy
to 2.5.1, in a few days, no doubt it will appear and I'll let you
know. zAmboni is investigating
RAM chip size and effects on times and he'll keep things up to date
as he digs deeper into that morass. To think it all started with an innocuous
posting in the alt.sci.seti newsgroup. I've recently
updated myself of that resource and after churning through 500 odd
emails (10 days or so backlog) became thoroughly depressed. If it
wasn't for the several regular contributors I'd have given up, such
is the dismal standard of many postings. Now I remember why I
stopped looking at it in the first place. Sad and jaded - that's me.
Before
launching into the benchmarks, in case any of you need reminding
what real power means here's a casual hint from guru
with one of the last postings on the old
boards...."I just got my phase I server running. I added
220 clients to it. Have fun with the stat's now. 107 of them are
dual processor machines." Onto some benching goodies...
Fastest K6-3 title goes to Ralph Morse
who's managed a seriously speedy 8:09 with the NonIntel client. Nice
to see another Celeron II time from fsgray but
it is hard not to feel sorry for a chip running at 850MHz that only
manages 7:24 (and with CAS2 RAM). At least you can chop 25 minutes off
by using Win98 (see sofaking at 7:03) - not much consolation if
Win2K is your OS of choice. Speaking of Win2000 fsgray also
ran a bench on a PIII with said OS to return 6:50 which is 2 minutes
inside NT4 run on the same system. Finally a reasonably speedy (for
an Athlon) time from enabrein
of 5:27, fastest Athlon so far but there's not much more to come
from these cpu's that definitely don't pull their SETI weight.
Couple of minor points: Xibo
those are very sexy numbers you submitted and I'd appreciate if you
could get intimate with my email address to give me more info on the
hardware. Talaktalan,
I have your times and they are included in the results table (update
will post soon) but I really need some input before trying to
explain/present them!! My AMD shortcomings being exposed here. Right that's
all for now, but there are plenty more times to come soon - I know
I've just looked in the submission sinbin...the benching wheel of
fortune rotates another cycle.
Max out.
Linkage
Guy was nice enough to send in some interesting links for
your reading enjoyment. The first is a review of the new AMD Duron,
this one running at 700Mhz. It has Seti benchmarks too! While it's
not the same work unit as we're using, it does have a database of
other systems to compare
it to. There's also a review of the new Abit SE6 motherboard,
which is based off of the Intel 815E chipset. Kyle 'The Man' Bennet
over at the HardOCP gave this one a good once over, and used several
interesting words, such as suckage.
And lastly, a very handy and informative guide written to help make
sense of your Bios settings is up over at 3D Spotlight. It's written
in simple English, and it doesn't tend to rattle on and on like I
do, which is a huge plus.
Just on a quick aside here, it looks like I won't be able to setup a
Seti forum myself after all. I'm going to be moving in a month and a
half, and I found out the only options for connection in my new
place are 1)cable- no dedicated IP, or 2)IDSL- slow and expensive.
So I'll be going with cable instead of DSL. Damnit. -Rat
Benchmark for the common
man...(think PIII not ELP) plus more action.
A quick look at the 'Oh...my...god'
headline (Friday, June 23) on Rizenet
should give a chuckle and big pause for thought, the thought being
what will Seti crunching times be with that memory bandwidth, gulp.
If it hasn't been mentioned
elsewhere there are two new Seti@Home
newsletters dated June 19th. Number
3 deals with spikes, way back (when total numbers of users was
still in 6 digits) they used to post updates but stopped because so
many turned out to be interference or hoaxing but if you would like
to know what they have discovered take a look. Number.
4 concerns the gaussians we've collectively been sending back by
the truckload. No aliens so far but the background on the results
analysis and interpretation is very interesting. If you don't like
reading there are the obligatory rectangular graphics covered in
brightly coloured dots - something for everyone.
Okay
lets go straight in and talk benchmarks until I run out of
submissions to offer and fingers to ram into my allergy stricken
eyes, though yesterdays pool session with leaky goggles could have
something to do with it. Chlorine, gotta love it, loathe it or swim
in it! An initial offering comes from d2s
who rather intriguingly is running a K6 233 (claimed) at 133 (young
people nowadays - it's all drugs, loud music and underclocking, the
planet is falling apart) and perhaps not surprisingly takes 37:35.
So now we know how slow it runs how about really giving it the gun
at rated speed! A big and predictable leap to Al
Bartenstein coming straight in at
12:58 (sounds more and more like a top 40 chart show from the late
70's, pop-pickers) which is middle upper range for K6-2's in general
and only 30 mins off the fastest one running a Linux variant. Next
up is Jeremy Crawford
who fortunately emailed me with a more sensible time than the 681
hours that first appeared in the submission sheet dungeons! His PIII
ran a 5:49 on a modest bus of 117MHz. Respectable is the word, some
faster OC'd 450's, some slower so there should be some tweaking
leeway in there. Stay keen and enthusiastic and don't let the
old-timers drag you down.
We've had multiple benches from several people over the months but I
think Steve Common
has reached a new level of dedication (read sycophancy) by
submitting eight at one sitting. I will simply say thanks and
hope you have got that lot out of your system for a while to allow
me some respite. Seven of the times are running on a 644MHz PIII at
a 143 FSB with a BE6 mobo and CAS2 RAM, so at least the hardware is
solid while the clients and OS get swapped around. First up, running
BeOS and 2.5 Cli produced 5:34 - the second fastest time for this
rare OS. Next up comes DemoLinux with the 386 and 686 2.4 clients
both yielding 5:02 (the precise timed difference was 1.43 seconds as
if it mattered). This area, 4:20 to 5-ish, is where the seriously
OC'd non Xeon PIIIs congregate and relative bus speed determines
your placing almost exclusively. Coming next is the 686 client again
on DemoLinux but going back to the v2.0 yielding a 4:59 to claim the
first sub 5 for Linux, yay! Steve's
remaining four times are all on Win98, 4:44 for the v2.0 client,
4:42 the 2.4 and 4:38 for the nonIntel 2.4. Finally after deciding
that the nonIntel was quickest (think I could have told you that
without wading through the benchmarks) he squeezed the bus to 146MHz
and still holding onto CAS2 produced a time of 4:24. Excellent time
but unfortunately the same as his previous best using a 160 FSB at
CAS3. Even more impressed that someone is using Tweakbios
which is a little fiddly but allows many untapped bios settings to
be altered. Also the documentation gives explanation to a lot of
unusual settings that might help anyone using AGPinfo (from IXBTlabs).
Usual warning about locking up applies - it can and
will! Suitable (?) for lots of chipsets with the last revision I
noted being 1.53 way back in March 1999 so it's either stable and
mature or old and ignored...This paragraph of benches is due
entirely to Steve Common,
thanks.
Even after those efforts there are two more times of real interest
(i.e. speed freak worthy). We have our first 1Gig PIII
(hooray, if Intel and AMD can make a fuss who am I to buck the big
Chipsters) from Marzio Nieddu
who has pushed his PIII 700 (155 bus and CAS2) up to 1085Mhz to
achieve 4:23, excellent stuff many thanks for that. A couple of
things to note here are 1) how clock speed becomes irrelevant once
you get to high FSB's, 2) how PIII's are topping out in this region
(4:20 or so) and a Gig clock speed confirms this. A sub 4:15 PIII
looks chancy now, let alone nearing the sub 4. I'd be interested to
see Marzio's
benchmark using a quicker OS such as W98 to see if there's much
difference (any chance?). On slower clocked systems Win2K can be half
an hour in arrears of Win98. Finally over to our recent smug bastard award
winner ('my toy is faster than your toy') Action
who has yet again defied the Gods.
Swapping from the 2.0 to the 2.4 client has chipped another 2
minutes off to stand at 2:09. Also realise this is for 2
benchmark WU's crunched with that dual Xeon set-up, very impressive indeed. How about the nonIntel client next? I expect to be potty
trained for your next submission.
On an end note the current Ars
Seti thread was finally curtailed at page 51. Here's a link to
the new thread, Team
Lamb Chop (SETI@Home) - Millenium. I personally like lots of
pages but it seems I'm in a parasitic minority of about one. I'll go
quietly.
Max out.
Lights,
Action, Music...
On the utility front Setihide
was reported to be revised up to 1.3 (beta) on the 16th but I
haven't checked so you'll have to take pot luck. Hot on the heels of
Setihide is Setidriver
which promises many things especially for those of you running
multi-cpu systems who need a little more thought in stacking and
working with those cached WU's. Bet that got your attention. I
haven't tried it (big cop out) but the SetiDriverInformation
post from author (Michael Ober)
certainly suggests a great deal of pleasantness. Thanks to that nice
ColinT for alerting me to that.
Hopefully he will keep us informed (yet again) of it's pro's and
cons.
Several times to report (which covers the fact
that I've already exhausted the info type stuff). So straight in
with Mournblade who is still
persevering with his system and has made it to the lofty heights of
13:41. I know he's chuffed because he told me so and it's all down
to cranking that bus just a little to 105. This originally started
out as a plain P233MMX on a socket 7 board and over the weeks he's
reduced his time, from 14:32, by close to an hour. Though many have
cut off bigger chunks it's good to see someone in the 'middle
ground' finally get a result. A new name to me is RatPhish
whose OC'd 552 Celeron stumps up a solid 7:56 with NT4. Starting out
at as a 400MHz (6 multiplier at 66 MHZ) your OCing is at the point
where most Celeries hit their cpu clock limit at 550MHz. Unless
seriously cooled or you have a really good chip (or both) any higher
bus speed is unlikely to be up and running for long, but you know
this already don't you. Finally in the mere mortal time range system's
system is in at 7:30. You are pretty much at the FSB limit with
112MHz as PIIs do not take kindly to big OC attempts. But if as you
say, you really haven't used any tweaks then there is a long way to
go with bios and CAS settings. Sub seven heaven coming up soon.
Onwards into the gladiatorial arena that is sub 4.
Steve Green has been hard at
work on providing several benchmarks on a Compaq 6400R (2 cpu's
installed of 4 possible). To say that the results are close is an
understatement, only 3 minutes separates slowest to fastest. Running
one client on Win2000 Advanced Server and then again with NT4 Server
produced 3:49 for both. A little spooky as I would have expected a
few minutes in favour of NT at least. Then running two instances of
the client produced 3:51 and 3:52 in favour of NT4. Finally running
the client verbose (i.e. it talks a lot - it's been that kind of
week, apologies) but only with Win2000 server produced a 3:50. There
is a gaggle of 1MB cache PIII Xeon (all at 550MHZ) times just
hovering above the 4 hour mark so this Compaq setup does appear to
have the edge by about 15 minutes. Thanks for the numbers. Up a
notch in the time stakes and Angus
makes it to 2:29 with his HPPA 8500 RISC quad processor system which
if you are interested is number 6 on the speed list. This
improvement of 12 minutes is due to only running a single client
whereas the previous 2:41 was also chewing away on other 3 random
WU's and covering it's regular workload (!). But competition here in
the 2 hour slot is really hotting up and who better to apply some
heat than Action who has pushed
the bus to 112MHz on that new PIII Xeon. 'Goddammit just tell us the
time', okay, okay let me put some fresh diapers on and let you know
it's 2:11. A 15 minute improvement in time (from 2:26) is 10% which
relates nicely to the 12% increase in bus speed - not that the
working set spends much time on it as it all sits in the 1MB cache
anyway. Remember we are talking expensive but not exclusive hardware
here, you can buy this sucker and mobo for a months salary (better
be in a good job, though). That sub 2 looks tantalisingly close.
Stay tuned.
Finally, many, many people have been expressing their delight on the
thread
that zAmboni's stats now go
through to 2000th position. This is great news as not knowing your
position relative to other LambChoppers
was a major downer to many outside the golden glow of the top 200.
Appreciation and congrats from this end of the world also.
Max out.
Quick
Update
Angus let me know about a small time mix-up and that has
been amended in the June 9 news. Also Joey
pointed out that his 4:45 with PIII and Rambus was more relevant for
its relatively low FSB than for having for a large clock (913MHz).
His bus of 114 is way below that of comparable times on PIII's where
133 and up are the norm. So perhaps Rambus is not so lousy after
all, merely under-optimised, over-hyped and overpriced. I know
things will change when Intel either sorts out its implementation
problems (as the 815 mobo purports) or quietly and expensively drops
it (not very likely). On the subject of memory there is a long review
of the history of PC memory at firing
squad. At 15 pages it's fairly long, but if you find this
subject as confusing as I do then this might help bring you up to
speed in an intelligible way. If you want to skip ahead (5 pages)
and miss the cutesy intro stuff then start at main
system memory . One time to mention is gkoum
with a 6:19 time on a PIII running Redhat which is relatively slow
but due mainly to that low bus of 105. Usual tips apply - bios
tweaks, then FSB and CAS2 assuming you are headed that way anyway.
Look forward to your progress.
Max out.
Quick
Update II
Thanks for all the well wishes from everyone
regarding my current illness - I'm starting to feel better now,
except for a sore throat from Hell. Also, for those who sent in
employment info, thank you very much! I'll be ending my 2 week
vacation tomorrow, as I start at American Express as a Help Desk
Analyst. Not precisely what I wanted, but it'll pay the bills. As an
added perk, I should have a decent view of the Minneapolis skyline
too, since I'll be in it. Of course, parking is going to suck
hardcore, but that's life for you. Perhaps I'll get lucky and find a
spot where I can park for less than $13 dollars a day, that would be
a nice bonus. Umm...that's all, I'll stop rambling. I have some
things to work on that haven't gotten done due to my illness and I
have enough energy to get them done now. So I better get busy. -Rat
Submissions from
the dawn of time (roughly 2 weeks ago)... part 1.
A whole shedful of times coming up
very shortly after mentioning that Setihide
has progressed to beta 1.2, which as mournblade
pointed out would make more sense as 0.2 and ColinT
who is giving Setihide a good testing suggested to the creator (Mel
Brooks and Young Frankenstein come to mind, an errant thought) that
a logging feature would be good. Personally I'd rather Roelof
who's been quiet lately, adding wu caching to Setispy!
But then I want everything. Guru
has been in front of the law recently in a number of ways (see thread
-'they just do') and my sympathy goes out to a fellow biker, mine's
a YZF1000, so yes another person who overclocks cpu's loves to ride
around, square off footpegs and waste rubber. Symbiosis on two
wheels.
On with the times and first up
is Urugami
with a rather lengthy 80:46 on a K5 at 133MHz which makes any Cyrix
look good! I would imagine you were hoping for something slower to
be able to take over the bottom spot though if squeamish
or RAOF
(see June 5) ran a benchmark you'd have no chance, if you two are
out there let me know what your using. Talaktalan
has been very busy
(again) with old Intel chipsets (where old means anything pre 'son
of Rat'). A 120Mhz Pentium on an FX and FPM DRAM produced a 34:31
and the 166 on a VX with SDRAM 20:59, just goes to show that old and
slow will still push out units if you have no better use for
them. Another pair of WU's ran on a 366 Celeron, the 2.4 686 linux
client giving 12:31 and the 386 an 11:20. After a previous
comparison (18:52/20:29) using the linux 386/686 clients I think talaktalan
has given in to the
obvious conclusion that the 686 is just slower. Finally back with
the linux 386 client he upped the Celery bus from 66 to 75 but only
improved his time 13 minutes to 11:07. Which is a little odd and is
probably something to do with the chipset (Intel EX) performance
limits. The only direct Linux comparison I can find is Steve
Common's old time of
9:19 for a 400 Celeron though using a 686 client to confuse things.
Feel free to let me know if I'm missing something deeper.
Still in the slow but sure lane a rare appearance of Win95 coughed
up a 25:32 for wehringer
and as he comments it's no
match for SuSE running on the same setup (18:41). After a long
absence Redbeard has
reappeared with a salvaged Pentium saved from dusty oblivion - a
small overclock (naturally) to end up with 17:43 and he seems
pleased. Okay that will do for times on the geological scale, lets
get into the middle ground.
In with a whimper is Mirage
with a 10:51 from a
PenPro sporting a ramdrive. Don't let the ramdrive fool you
this very impressive time is due to the 1MB cache L2. Though
PenPro's at 166/180/200 were ubiquitous workhorses only a couple of
years ago, I have the vague feeling that the 1MB cache is rare.
Unfortunately not very OC-able either. Steve
Mac G submitted a K6-3
time of 10:34 which has got to be a slight disappointment, running
W98 and the 2.4 client you should be looking to knock about an hour
off that.
I find great comfort in the slower times but right now I need single
digits. A second time for Urugami
using a 'new' (why, do they wear out...) 500 Athlon giving 7:56 is
okay but could do better (school reports haunting me there). Don't
hold out too much hope for overclocking as a scan of the table only
shows a couple of Athlons over 110 FSB, find a cool, dry cellar, big
fans, rip the case off (heresy) and go from there.
Another fast Athlon (600MHZ) but slow time for shirty
at 7:54. There is some slack to picked up on, but you'll struggle to
compete even with 500 Athlons (see Urugami)
while using NT4. At present this is the only Athlon in the table not
using Win98, could this be related to a lack of gaming pretensions
dare I wonder, not that any of you would forego a couple of hours
crunching alien signals as opposed to crunching aliens. Lastly in
the Athlon benefit arena we have Joe
Bucker whose 600
Athlon has produced a very respectable 6:32 - bit more like it.
Next up is Angus,
a Dell laptop and a battery bursting 7:37, don't leave home without
your mains adaptor. It's a bit behind Actions'
Inspiron7500 at 6:56 but is a reminder not to leave valuable Seti
resources untouched. Suggest you go get a Coffee/Benzedrine/favourite
Shari Lewis poster/whatever as there's more to come...
Part 2
Slight discourse: Ram latency reduction is a very worthwhile
improvement but L2 cache latency is not something for most of us to
be worried about, (unless of course you are a Rambus owner) as you
might get a % or two if you're lucky. Speeding up movement of Seti
data on the bus is going to hugely outweigh any L2 latency reduction
for almost all cpu's. At 1MB cache, the Seti working set fits in the
cache and L2 latency theoretically becomes important. We are now in
Xeon territory where the cache is heavily optimised and L2 latency
reductions are going to produce instability rather than speed. One
school of thought is that increasing L2 latency can improve
stability and allow a greater overclock, this of course is only true
if it is the L2 that is the major factor in limiting your
overclocking. One way to find out is by disabling L2 in bios, does
it boot, yes, then probably L2 cannot handle the CPU speed. The
Celeron is a good example where a higher bus is possible if L2
disabled but of course without the 128kb cache, performance drops
dramatically. Increasing L2 latency might allow you to POST or even
partly boot at a higher FSB but to actually achieve OS stability and
then stress it with Seti (or RC5 or Prime95) is a whole different
game. Your max. FSB is most likely going to be the highest FSB you
can run reliably at default L2 latency, 15 minutes and blue screens
and/or locks do not count as stable! It would be lovely to report
that latency reductions were going to help but overall it's a bit of
a sideshow. So after all that thanks to fsgray
who dropped his L2 and recouped 79 seconds to go to 6:47, was it
worth it. A Speed
Demonz article (8 pages by Adrian
Wong, if the link
holds up) from way back (Dec '99) attempted to show what changed L2
settings could do, the outcome being 'very little and not a lot'.
The article has questionable methodology but at least it's
something. If you still feel like a little tweaking then WCPUL2 is
at H.Oda.
A Celeron II time now from Steve
A with the words left
to him. "I got my first Celemine 533 the other day and set out
to SETI it right off. I obtained a FSB of 110MHz for 880 on chip
with 1.75V. This produced a time of 6:36 on the same platform that
yields 4:18 with a 550E at 825. Yawn. My 533a failed at 112FSB (896
on chip), even at 1.8V...Since we can't raise the FSB on the
Celemine over 110-115MHz, even good 300a times with a 124FSB are
better. I have speculated that this is not absolute (wu's with
guassians profit from the extra on chip clock), but even then it's
within minutes of the truth." Because of that unpleasantly
large multiplier (8) on even this the lowest clocked of the new
Celeron II's the opportunities to OC are very limited. 880MHz sounds
great but for Seti remember, as always, the bus comes first and the
clock speed follows way behind in importance.
Bylee's
400MHz PII Xeon managed two WU's in 5:39 with W2K, that 1MB cache
working rather well. A rather delicious time but now get rid of the
crud you say you have running in the background and get a sub 5.
Continuing into the mid 5's is nethead
with 5:25 on a PIII/133/800. A little more bus might see you to a
sub 5, then give us that BeOS (see his/her comments) time, think I
smell rubber burning. Another Xeon (PIII 400MHz, NT4) time now from Hance_wu
with 4:48 which is just about where it should be. Next is a dual PII
Xeon from Angus
at 4:46 also running NT4 tied with a much faster dual PIII
(133/800MHz) from Feisal
also at 4:46 which just happens to be the fastest Win2K box so far.
These high 4's seem to be the place where the really tight
competition hangs out. Anything to gain a minute even perhaps dodgy
L2 latency settings! A short shuffle along is
Joey at 4:45 who
has the honour of submitting the fastest cpu to date (as if it
mattered) at 913MHz (PIII with PC800) and another confirmation of
how far Rambus RDRAM has to go before it's worth shelling out the
big money for such poor memory. It's a useful improvement on Charitys
5:12 RDRAM equipped box but is still way short of exciting. A
staggering 166 bus for Tomslik
on his PIII is yummy but running the RAM at CAS3 naturally keeps the
time to a sedate 4:43. There are several of you trying to get really
high FSB's (150+) at CAS2 to run but I'm beginning to wonder whether
it will really happen. Is this another barrier? A big leap now to a
real goody. A monster time from Actions
new baby, a 700MHz PIII Xeon, coming in first time at 2:26 for 2
bench units! Think I just wet myself.
I'm glad to read in the thread
(zAmboni
June 5, 22:37 ) that I'm not the only person who mailed the Register
and didn't get a reply about Seti matters. Since I wrote seriously
and on topic I consider that rather unprofessional. Shame. There
have been a bargeload of Duron/Thunderbird/Timna offerings the last
few days and several interesting links from posts. It seemed better
to get this out and done rather than chase after stuff that will
have lots of linkable reviews in the next few weeks. I'm just three
people after all. Finally as this is a big update the usual proviso
about errors/corrections holds, you tell me and I'll sort it.
Max out.
To hide or not to
hide that is the software question...
A few bug fixes for Setihide
and it becomes version 1.1, still considered beta though.
Folks on the thread
seem enthusiastic which means that someone else is trying it out and
reporting back, good. ColinT
has some useful impressions and a thoughtful review on page
40 (June 05, 2000 16:49). Remember how in the mists of time
you ditched the GUI for the CLI and received a pleasant time
reduction, so why go back a step? Who needed visuals anyway? But If
you hanker for something on your screen that shows more than numbers
then this is a good compromise. With the WU caching working properly
it could be very tempting to use. The peaks and troughs of the main
window's graph show many of us what we already knew that the client
work rate varies considerably depending on the FFT set size, the
frequency resolution and gaussian considerations (where present).
Yes, you can assign an overall efficiency to a processor but at any
particular point it could be well above or below this. So it
visually answers some peoples questions about instantaneous
processing rates that Setispy
shows up. Personally, I still have the fundamental reservation that
it is taking too much cpu time, as you might expect with anything
that provides some mild graphics output. Which means you times will
increase and production down - nothing like stating the blindingly
obvious. I guess that means I'm in the speed freak camp in spite of
the odd sympathies I have for tortoises. If you can come up with
some real benefits of Setihide let me know and I'll mention them. I
don't want to appear to negative about someone else's hard work. As
before try it and decide.
Guy Olinger
pointed me to an article at tweakmax
about memory timings so if you like your comparisons simple, clear
and with Sandra
FPU/CPU numbers over a range of different FSB settings then CAS2
vs CAS3 (3 pages) is for you.
First there was the competition
then the results
and now the Rambus
rumble which is not as exciting as I've made it out to be!
Considering our views on the sad implementation of Rambus on Intel
820 & 840 chipsets and it's disappointing Seti crunching times
(the oft quoted Charity
and 5:12 with PC800 springs to mind) the Register
is still looking for a champion of sorts. But it is good that a more
mainstream site occasionally covers Seti stuff even if the pace is a
little on the slow side.
Those of you who have submitted benchmarks or pointed out minor
errors (thanks - honest) are being patient and sometime soon I will
get down to putting them in the results table and making unreasoned
and vaguely caustic comments about your efforts, that's why I get so
much fan mail. At present the slight hitch is that they are all
located on Rat
Bastard's old server (mediaone.net)
and though not lost are presently unavailable. He is trying to sort
this out along with looking after a baby, finding a job, flying
radio controlled planes, writing here, setting up a forum and
sleeping - really not busy at all.
Finally, since helping (?) out here I have subscribed to, signed up
and chased down so many links and mailings that my inbox is a little
crowded most days, very ego boosting. Shame that so little is worth
passing on. A while ago I came across some freeware called mailman
that allows me to see what's there and delete the dross before
downloading from my mail server. It's on beta v5 but seems stable
and very clean. As mentioned previously I'm on a modem connection
and anything that cuts out the crap is useful. Also on a
non-Seti note if anyone has a serious link to the 'Eureka,
scientists break speed of light' mailing I just got let me know.
Update - Ars front page has provided one to the NY
Times (not a scientific organ the last time I read it), thanks
people. Here's a quote:
"The work was carried out by Dr Lijun Wang, of the NEC
research institute in Princeton, who transmitted a pulse of light
towards a chamber filled with specially treated caesium gas.
Before the pulse had fully entered the chamber it had gone right
through it and travelled a further 60ft across the laboratory."
(Feel free to giggle). The team claim 300x c which sounds like a
windup but you just never know, but then I am writing this from the
far future... I'm sure a Danish scientist was mentioned on the
BBC science site a while back about using lithium ions to slow c to
walking pace, the punchline being that she was able to go get a cup
of coffee and come back before the beam crossed the room. Enough
already.
Max
out.
In praise of the
Tortoise...
News and hot topics in the Seti world
seem to come in bursts and right now things are a little on the cool
side. So I think I will go for the soft option and provide a few
links, thoughts and minor ramblings. The thread
as always is full of interest and thanks to ColinT
for giving me an Athlon overclocking link
that suggests going lower on the multiplier and thereby being able
to up the bus. Note, the article has faq links about using 'gold
fingers' to change the multiplier or try this little
explanation and the benchmarks are game oriented but the
idea is sound. We know higher fsb's are better for Seti but
not everyone can change the multiplier. ColinT
took this to heart and tried it out going from 8.5x104 (884MHz)to
8x111 (888MHz). Sorry no results yet, I will be as interested as you
when they appear. Anything that can give the hamstrung Athlons a bit
more help will be good.
ColinT didn't end there and
reported on a new utility for Seti monitoring called Setihide.
Two programs are in the 305kb zip, one for managing/displaying Seti
info and one for hiding the client. It is definitely beta and
a shade flaky but always good to see new ideas. I'm sure Roelof
will have a few comments as it is stepping into his territory but as
yet nowhere near Setispy
in quality or info. It's main visual attribute is a graph of wu
processing % per hour, interesting but not much more illuminating
than the GUI display. Unfortunately even minimised it is consuming
about 5-6% of cpu time (Setispy takes around 0.15% when monitoring)
so has quite an impact on Seti crunching time. Claims to be able to
cache 50 units but I haven't tried so unable to comment. Download
it, have a look and then decide if it's any good for you. I'm sure
that it will improve in efficiency and presentation with updates but
at present is not recommended.
Also from the thread
was Mr Petey's observation in
praise of team members with high average times citing the 53 wu
production from Xyberknight
averaging 117hrs. Extremely impressive, I always maintain that the
slow stuff merits more attention. There are several members
averaging over 100hrs with special mention going to Immortal1
who's produced 10 at 130hrs each to be at 1713th place. Spare a
thought for squeamish (1886th
place) who's 4 units average 167 hours. Finally, to do one
unit slowly is impressive but then to knowingly do another is real
class so I think RAOF (1990th) averaging
242 hours for 2 units must take pride of place. A special breed of
Seti cruncher indeed.
In the quest for faster times keeping your system cool is paramount.
Before persuing peltiers/fridges/water cooling/liquid nitrogen a
simpler first step is a new
case. More fans equals better (and noisier) so a box with 3
extracting and one blowing in from the bottom as standard has got to
be worth considering...but I was more interested in the testing,
stuff the box into a green bin liner for 30mins and see what happens
- answer, it gets hot. Note: If you are on a modem (me for instance)
the pictures take a while to download.
If you can't get enough comment on Rambus then check out the Registers
SiSoft Sandra numbers for a 933MHz PIII on an Intel i840 equipped
(dual channel memory chipset compared to the i820) board. Yes the
mem bandwidth numbers are heading in the right direction but the
comparison with an 800 MHz PIII BX chipset with a 100FSB is a little
misleading considering we know that the BX is good for far more.
Rambus is not for Seti yet, spend your money more efficiently
elsewhere.
Finally here's a reason for those of you who don't post to the
TeamLambChop thread to continue not to, courtesy of Mr
Petey...you have been warned.
"Hello, my name is Mr Petey, and I am a Arsaholic. I have been
reading Ars for a year and a half now. Then about nine months ago I
started hanging around in the forum reading the odd thread here and
there, what harm could it do? Within days I was posting. Soon, all I
could think of was posting.
Then my girlfriend deserted me. "Good riddance to the
Cold-Hearted, Blood-Sucking Bitch anyway!" Said I, for she
would never understand the Joy of Posting. Who needed her cold
comfort anyway when I could Post?
With nothing to hold me back I posted like a man possessed.
Eventually my fingers screamed stop, but I posted any way. I posted
like no man has ever posted before...I was the GOD of the
newsgroups. Nerds and web surfers from across the globe came to bask
in the wisdom of my posts. Then, my fingers gave up. Forced to walk
among the Netless I knew I had truly reached my darkest hour. As if
from nowhere, a ray of light appeared. Voice recognition software!
Joy of joys! I could post again! ...Here I sit in a broken down
shell of a house. Guarding the last functional telephone line in
town with my twelve gauge and ring of proximity mines, with the only
the glow of the monitor for heat and light. Alone in the knowledge
that I am responsible for the social and economic collapse of middle
England. All I know is that I WILL Post. Maybe not while installing
the server, maybe not till after lunch, but soon and for the rest of
the afternoon...."
I know I'm into computers too much when mention of the Rascasse
corner at the the Monaco Grand Prix only makes me think of memory
timings - sad.
Max out.
Seti and the
search for intelligent conversation
Well, I've received a lot of mail concerning the possibility of our
own dedicated forum for Seti discussions. And with the exception of
one person, it was agreed that the dedicated forum would be a good
idea. Of course, I'll have to post the question in the current forum
too, I'd like to get everyone's opinion. However, I think
we'll probably end up with a dedicated forum. So I went ahead and
tripled the CPU capacity of my server today, and quadrupled the
memory. So now it's no longer a POS, and should be able to hand the
UBB just fine. So, where is it? Umm..hold on there, I'm not done
yet. Okay, I'm not close to done yet. I'm still waiting for some
parts to arrive so I can get my SCSI drives online, and then I have
to configure everything and stuff. In short, it'll be awhile. But
I'm working on it :) And with that, I'm going to wrap
this up and get back to work. -Rat
The hunt for
meaning
I finally went ahead and did the one thing that I've been meaning to
do for a while, I quit my previous employer. I think it was a good
move overall, as I had no potential for advancement with the
company. After all, they want techs to have 4 year degrees- and make
$15 dollars an hour. I don't think so. So I'm currently looking
elsewhere to see what I can find. It's tough because there isn't a
huge market for hardware support people, and I'm hampered by the
fact that I don't have a degree. So I'll find whatever I can, and I
think I'll be spending a few years at a local University too. About
4 of them. I had too much spare time anyways :)
If anyone in the Minneapolis MN area needs a fool to come in and
overclock all of their workstations (and put hidden Seti installs
on! :P ), email me!
I doubt I'll hear anything, but it never hurts. After all, the last
time I mentioned something like this, I was looking for a bed. A
gentleman with Intel forwarded my request to a cousin who sells
mattresses wholesale. It's amazing how things work sometimes.
Continuing on my thread of ranting, I'd like
to congratulate Geordie, who
scored an excellent deal on a Quad Xeon board this weekend. Sounds
like he'll populate it with 400 MHz Xeons, meaning he can crank out
20 odd units per day from that one machine. Nice! I'd also
like to welcome Knight to the top 200, 'bout time he got here, the
lazy bastard. Knight is a good
friend of mine, we go out and crash R/C planes together when we have
the time. It's a blast.
On to some Seti related content. I'm currently
rebuild my webserver, and I've been toying with some ideas. I've
noticed that the thread
over at Ars is a little
disjointed due to several different discussions being carried out at
once. And it's hard to find info sometimes, because it's somewhere
between page 1 and page 38. If we started separate threads for each
item, they'd quickly become lost in the mass threading that exists
in the Ars forums. Therefore, I've been kicking around the idea of
hosting a UBB service just like the OpenForum at Ars Technica.
However, this one would be dedicated solely to us. We can
ramble on about the project, hardware considerations, and stats in
separate threads. I'm curious what everyone thinks about this.
Should I? I'd really love to get some feedback on this one, so feel
free to flood my mailbox
with your opinion. Be short and state yes or no, or spend time
telling me why you think that I should or should not setup another
forum. I honestly want to hear what you have to say. Thanks! -Rat
