seti@home? cure for cancer@ud?

[lhgpoobaa]

ive tried seti@home, ud's cure for cancer, & prime 95, and i must say that the cure for cancer seems the most appropriate way to utilise my processor.

anyone else have the same impression?

with my athlon 1386 i can churn through i job in under 3 hours! (for the smaller ones)

another question:
seti & cureforcancer i thought were extreemly FPU intensive... is this true? wouldnt the athlon then spank the P4 in this regard?

I have a p4 and i am second fastest on the Toms hardware guide team. So strange people say the p4 fpu sucks

 

[lhgpoobaa]

hmms. what kinda p4? 1.8? overclocked?

ive seen the benchmarks for PURE floating point operations and the p4 doesnt look good.
however... it rare to find a pure fpu app and the p4 has some other tricks up its slieve to compensate.
and who knows what percentage of the calculations is fpu with seti or ud?

P.S. whats your quickest time for completing a UD job? (assuming you run UD)

What's your time per unit?

- I got a board too: http/www.impactsites2000.com/cgi-bin/ikonboard/ikonboard.cgi

I run both UD and SETI... My regular UD machine is an overclocked Celeron II at 900 MHz and it chews up UD units very quicky, sometimes in under 2 hours... sometimes 3 or 4. It seems that the UD units are getting quicker, so I think they are doing something to optimize them or something. I'm running Win2k pro on this box.

SETI on the other hand always seems to take 7 or 8 hours per unit. My Athlon 1.2 gig can sustain about 180 Mflops while the Celeron 900 only gets about 140 Mflops.

It's interesting to note that I also have a Tbird 840 MHz. and it sustains nearly the same 140 Mflops on SETI as the Celeron boxes... I've always been a little disappointed with the Athlon's performance in these distributed computing projects... I just expected more. Certainly synthetic benchmarks show the processor to be a lot stronger.

Finally, I note that UD heats up my Athlon 1.2 gig a bit more than SETI, so I think it may be more computationally intensive than SETI.

hmmms.
yep. ive noticed the short jobs too. they have a new protein circulating recently.
RAS its called. ive finished jobs for that in under 2 hours.
(1386@154fsb)
not sure what i was getting with seti...
i have the habit of running other things at the same time so i could never get a realistic time.

while they say that the calculations are FPU intensive, i dont think they are any worse than any other application to be honest. so any differences between the athie & p4 architecture are neutralised by different speeds, architectures, cache sizes, memory bandwidth etc.etc.etc.
p.s. was reading a p4/athie article and while the FPU of the P4 is weak (takes 2 extra clock cycles to do any fp op), the arithmetic unit of the p4 actually runs at 2 times the core speed? thats 3.4GHz for the 1.7! thats gotta have an effect
also... UD is majorly sponsered by Intel... wonder if any minor intel tweaks have been done along the way?

The P4 FPU may run at twice the core speed, but it's not pipelined is it? I think that's the major departure for Intel. They pioneered pipelined FPU's and now they decided to depend on SSE instead and wait for the software to be optimized.

I wonder about the Intel optimizations on UD as well. I guess it doesn't really matter. The Athlons seem to function very well running code optimized for other processors... that's why they are such great CPU's!

My work-mate told me that the app that searches for the cure for cancer doesn't actually search for the cancer cure 100% of the time. He said that it actually spends most of the time trying to find new drug formulas for some major pharmaceutical companies. Does anyone know if there is any truth to this?

I'm all for finding the cure to cancer but I just can't get excited about helping some huge ($$) drug company find the next Viagra.

Well, in theory anyway, we're building drug/protein interaction libraries that researchers (including big drug companies) can use in the future when designing cancer fighting drugs.

I guess I don't mind if a drug company gets $$$ out of it, as long as it helps people with cancer, it's worth my time to participate.

My "handle" on the UD cancer project is 4Michael... in recognition of a very dear little boy who died 2 years ago from Leukemia after a 6 year battle which included a bone marrow transplant from his brother. He was 8 when he died.

I think I'm starting to agree with you LHGPooBaa...

I've been running SETI@home for two years now on all my computers 24/7 and lately I've been thinking of lending my computing power too a project a little more "here and now" valubale.

I'm planing on changing all my machines over to folding@home if I can get the guts too. I just hate the idea of getting so far in SETI and then just quiting...




I'm not new... I just change my name...

 

[Scout]

I know what you mean... I've got over 1300 units now in SETI and am now counted among the Elite top 20 on this fine Tom's Hardware Guide team! It'd be tough to walk away from that investment of time and effort... besides, Lowlypawn would pass me if I ever stopped!!! (who says I'm overly competitive???)

I also think I will leave my computer on all weekend to gain some ground

Ooops, I guess I shouldn’t give the enemy my battle plans.


Thx & Cya

Yeah, I run UD and seti@home all the time.
With UD when I set a larger allocation of Disk space i get a very large and time intensive molecule to work on, sometimes it takes 3 days (40 hrs) but the points returned is higher. An annoying thing about UD, after doing 20 hrs on a molecule and I shutdown it looses most of the time and starts all over again.

System at present> 1.4Tbird @ 1.5Ghz,8K7A+, 512mb Crucial pc2100, 30Gig Western Digital, cable modem.

use something called UD monitor man
get it to backup every 15 mins.
ive got mine to backlog 4 jobs, so i dont have to connect all the time

oooh sounds just the ticket! Don't suppose ya have a link to that. Will go have a looksee right now and try and find it.

Can find plenty of links for the download but no download :frown:

Ok found it, was a broken link but the guy fixed it for me.

ummm no
but if u visit the UD messageboards im sure someone there has posted a link.

few minor probs with UD monitor ive found, it doesnt send them all at once... and a bit f manual reloading is required at times,
also a few times now it has cauzed a UD job to crash upon "preparing to send to server" line.
just have to close both down and start up the monitor again

I was wanting to look into this "UD" site. Anybody got a link to there site. I've done a search but can't seem to find it. Just find a bunch of cancer info sites. I've checked out the seti site but it doesn't really interest me.
Thanks ahead of time.

 

[WiseGuy1]

never mind. Just found it. The whole intel think threw me for a loop.

There are couple of threads one should read before joining with UD, for example <A HREF="http/forum.ud.com/ubbcgi/ultimatebb.cgi?ubb=get_topic&f=10&t=000235" target="_new"> this </A> and <A HREF="http/forum.ud.com/ubbcgi/ultimatebb.cgi?ubb=get_topic&f=10&t=000250" target="_new">this </A>.

And after also reading <A HREF="http/www.wired.com/news/technology/0,1282,46982,00.html?tw=wn20010921" target="_new"> this </A> I joined with Folding@home. Why? Because I believe I can't find aliens, after reading those threads I don't believe in UD's sucess, but participating in Folding@home I can at least help IBM to do what I can't - discover something really important.
