Crunching for a while....

[David]

With a bit of help from Yodums I am now crunching for Overclockers.com SETI team. I got a bit bored of folding, and the SETI programs seem a lot better (being able to cache WUs is a godsend).

I don't know how long I'll be crunching for, hopefully my Thunderbird 1100 will help boost the team score a little.

I am also working on a few linux SETI things, will post more when they are ready...

David I love your avatar, no activation required.

Linux advice is super. Some of us Windoze droids are attemting to rev up K12LTSP (http://www.k12ltsp.org/) and find ourselves Linux challenged.

Welcome

Harvey

[Yodums]

Awsome David. Don't worry, you've seen the light now your sticking with it! :D JK

I hope you enjoy your stay.

Great to see you here. Now maybe you could make a bootable Linux CD with the SETI client on it. Humm..............

What about the diskless cruncher method? Have a Linux server, and the workstations are just mobos, cpu, psu's, video card and a floppy (I think), oh and can't forget the NIC.

'Tis precisely what I am working on.... are you a mind reader by any chance ? :D

All I need to do is take Overfoldix, remove the folding client, slot in the seti client (and setistack if you want to use it) and modify few init.d scripts and Overcrunchix 1.0 shall be born..... :beer:

I'll add my voice to the multitudes, Welcome To Our Little Powerhouse! I think you will find our band of brothers and sisters, equally as friendly and enjoyable as our counterpart "Folding Team". I have been following your adventures with Linux and Folding for sometime and am looking forward to what you might be able to introduce to our SETI efforts. As hallen said many, myself included are less than spectacular in the Linux world(no offense to those team members who have Linux down pat). Maybe somewhere, sometime, you and the other Linux wizards on the team could be imposed on to create a good step by step guide for the Linux-challenged amoung us to using Linux for SETI Crunching.

Anyway, Glad To Have You Here With Us!

Nah I like everything to be running all by itself. If the server dies I loose tons of time.

It took me a little while to figure out Linux Crunching myself. I use KSetiSpy just now, I am caching 20 units as I type.

Look out for a few linux bits and pieces in the near future.

David

[David]

Heres some stats. CPU is a 1.1GHz ASHHA AMD Athlon Thunderbird-B. I have 512MB of PC133 RAM.

Left it crunching overnight, the second unit was all completed while I was asleep.

David

Not bad times. However you will notice that with SETI memory bandwith is much more important. If you upgraded to a DDR MB you would be able to drop around 3 hours off of your times.

[KenCo]

Glad you could join us David! ;)

:eek:

I'm looking to get an Asus A7S333 mobo + DDR RAM soon anyway.

I had no idea that RAM Bandwidth made such a difference.

Would upping my FSB make a big difference? I can get it to 106MHz, so RAM speed would be 135Mhz if that would help?

It would save you a small bit of time. The DDR bost however is going to be much more noticable.

[David]

A few SETI n00b questions:

1) Are Intel or AMD CPUs best for SETI?
2) Is the client multithreaded or is it one CPU per client?

Thanks,

David

[RedDeathDrinker]

If you're OCing a Northwood to the high-2GHz level, it seems to do pretty well....;)

I run my XP1500 at 160MHz FSB (1600MHz) and get a unit crunched between 2.8 and 3.8 hours.

The 2.8 hours was a high AR unit (Angle Range, 3.784 in this case), done while I was sleeping, to the 3.8 hour Unit, which was a low AR (.0016 AR)

High AR work units take less time to crunch.

You can run multiple clients, but to no advantage over one. A dual rig can run one client per CPU.

Oh, and welcome to the team!

1) Northwood P-4's are producing the best times. Work units times vary based on the AR or angle in the sky. We all love whole number A/R's 1.00, 2.00 , 10.0, 11.0. because the take 20% - 30% less time to process than low A/R's 0.50, 0.41, or ugh 0.03.

For some reason P-4 bog down on the low A/R and take longer than Athlons. I think it's because the NW 512k cache is less effective on the low A/R's.

DDR is unquestionably better than SDR. A lot of the KT266A boards will run with fsb in the fsb 180's 190's.

2) Windows client is single threaded. If you run on a dual there is a "set processor affinity" box to check which will link one cpu to one process. Also this is for Windows.

Harvey

P.S. I love fishy's idea of a Linux install disk with Seti pre-installed. We could give them away like AOL cd's. Get the folding mailing list.

:D

I am probably going to get a new mobo/cpu/ram soon, and I was wondering if P4s had any great advantages over XPs. I think I will go AMD as I can't afford a P4 1.8A plus mobo plus 256MB DDR RAM.

Thanks again.

I am currently working on 'Overcrunchix', a SETI version of Overfoldix (see sig).

When I find the time all I need to do is slot some SETI stuff into the CD image and alter a few scripts.

David

[Yodums]

SETI is based on FSB, and memory timings. That's why a T-Bird 900 at 166fsb (DDR) will crunch equivilant to a Celeron at 1.5gigs. The Celeron won't have such a high bus, and the DDR Benefits. Unlike Folding, FPU barely means anything in SETI, it does some what but it isn't the number one concern, take a look in our benchmark page and it'll give you an idea of how memory and fsb takes place. Also the AR stuff mentioned is correct, and the benchmark is good because it is all the same AR (0.417, the most common one, or average).

David- That would be fantastic!! I could see selling them on eBay as a fund raiser or giving them away as part of our advertising.

Let me know if I can help in any way. My Linux skills are limited but I am working on improving them.

Harvey

[David]

Thanks guys. I think I'll get an XP1600+ and tweak the FSB up till the thing screams :D

Thats a good idea!
I will get something sorted by the end of the week hopefully.
Linux is GPL software: you can charge for copies but people can legally copy and destribute them if they want.

Morgan Duron's aren't bad either. You can unlock them 1.0, 1.1, 1.2 but not 1.3 with a pencil to get to the high fsb's.

This memory benchmark should get me to 3:50 with a Duron 1.2.

[Yodums]

Harvey, explain to me how the heck Kat gets to 3500/3300 with that KR7A-RAID! LOL. I would like to see how fast he crunches SETI.

Kat runs 200 - 210 fsb. His peripherals can handle it. Mine crap out in the 190's so I just stay there.

I use WDC Caviar 850MB drives and they're fine up to about 194 and only cost about $5. on ebay. I did pickup a couple of D-Link DFE-530TX+ which Kat likes.

To anybody who is confused Kat hangs out here:

http://www.dslreports.com/forum/remark,2988827~root=ocusa~mode=flat

and does amazing things. His preference is for Abit KR7A's right now.

I have the DFE-530TX and I personally think it's a great ethernet for like 10-15.00, just as good as my 3com 3C905B. I just think that 3500/3500 is beyond... crazyness. He showed his customer's KX7-333 @ 210fsb, and it barely broke the 3000/2800 barrier. He probably has some secret weapeons.

Hmmm.... I'm not quite at the point of getting a full blown distro going. All I have so far is a bootable CD which runs SETI in RAM :rolleyes:

See the other thread.

[hallen]

Thanks David- I'm downloading it now.

Maybe I can work on a distro.

Welcome to the Team!

I'm working on the K12ltsp setup as well......and I am linux-challenged.:p

So I look forward to write-ups and tricks and hints......also you may be getting some pms :D

I could make a version of Linux that is basically Overcrunchix but runs off a 64MB partition...
