Crunching tips

RAMMIE · May 28, 2009, 10:08 PM

1 A dedicated cruncher doesn't need more than 1 gig of RAM.1 stick is best.The single channel penalty is easy to make up with increased CPU clocks.CPU speed rules in these projects.
2 Timings and RAM speed don't matter much.Again go for CPU speed.
3 x64 OS and 64 BOINC client will get more points than 32
4 Human Proteome Folding creates a lot of problems on a lot of machines.Avoid this project if you see errors in it.

Feel free to add any tips!

This is a great thread to sticky...I think I will.

Does anyone know what operating system will yield the best results?

My server is running 8 x ~100 MiB projects now. I'd say 2 x 1 GiB sticks are ideal. You get the added benefit of dual channel and have room for the OS too.

I've done 207 results on Human Proteome Folding Phase 2 with zero errors. If you get any errors at all, you pushed the computer too far. That particular project might be harder on machines than the other ones.

My guess is XP x64 or Server 2003 x64. Vista usually only sees gains in gaming because of DirectX 10 and a loss in pretty much every thing else. Windows 7 might be on par with XP x64/Server 2003 x64.

For a i7 with HT enabled or a dual CPU setup 2gigs would be needed.For a dedicated cruncher with a Quad or less 1 gig is more than enough.

I run server 2008 x64 on most of my machines.

i see WCG using about 100mb per project at any given time? are you sure you really need more than what you use + maybe 512mb or so?

123bob · Jun 1, 2009, 05:10 AM

Control laptop temps (or your desktop if you're having temp problems) by using the profile parameter "On multiprocessors, use: XXX % of processors".

I used to run my lappy at 60% to keep it running cool. It ran for over a year 24/7 doing this... This puts a sawtooth looking pattern in taskmgr's performance tab, as the processor is turned on and off.

Also, one of the common new person questions we get is why the processors are not loaded 100%. The default setting of this can be 60% when you're just starting out...crank it up to 100% is you want max production.

Shown below is what it looks like on your WCG profile page.

Here's a good one....

Check to make sure the bios time and date is set correctly on your rig!!

If you don't, you may not be able to connect to the servers since they use time sensitive certificates for authentication. It will drive you nuts to figure out why you can't get work!! A few here found this out the hard way....

# of cores + endurance rules..

not GHZ...

Avoid high end ocing unless you have a large budget for hardware replacements.

(the story of the tortes vs hare)

A lot of XS WCG people (me expecially) did a lot of hardware replacements to hold up high overclocking while being loaded. If your not the type that can RMA stuff fast, or its your main machine, down the overclock so she's not tiptoed all the time.

Oh and when your cruncher does suffer from down time.. (unfortunate event but will happen)

1. most likely its your RAM
2. it then falls on the board.
3. the cpu is usually the last to die, unless your pushing 1.5vcore + on WCG. :P

There is a balance between extreme overclock and durability. The Ghz is what does the work, so more Ghz= more work. the combination of more cores and higher clocks yield more work. Myself and many others have the experience to know. I have had a very durable long running farm using this premise.

Fast CPU
medium-slow RAM
That's the recipe

yeah its true that ghz does matter.

but XS has histories of enterprise machines outlasting any overclocked machines.

And most of the enterprise machines are only bsel moded.

Because people want to run their RAM at 1000 4-4-4 and you need volts for that.I did it for a long time.Now I run loose timings and keep it stock speed.My output hasn't declined and I haven't killed any more DDR2.

I know XS and I know who you are, and I was the #12 or #13 XS WCG team member.

I have made my bones and know what I talk about concerning crunching.

All my machines are overclocked and ran 24/7 overclocked.

I always have run my ram at default or less without issue, except for a bad run of Crucial Ballistix many years ago.[I have a whole box of dead Crucial]

And most of us cannot afford enterprise machines.Most that run them can't out perform Mike and Mike.

Dude... im leaving this thread because i got a very rude PM from someone id care not to disclose.

Anyhow... its really sad because i crunched with a lot of ya for a while and to be treated like shark meat really hurt.

I wish your team the best... as for me... i hope the guy reflects on what he just did and not repeats it to anyone else.

stanhemi · Jun 5, 2009, 09:34 PM

well i don't know your storie (about the p.m) but if people on tpu wcg treat us like that .......

it sad i fold since november 08 and never had problem.but i'm new to wcg tpu.

I am the guilty party.
Didn't think it was rude to suggest that he crunch with such high end CPUs instead of just giving advice to buy high end platforms.Sorry if I ruffled your feathers.

Laurijan · Nov 2, 2009, 04:39 PM

Should i limit my crunching to the project that has given me the most points so far? And if yes how do i select the projects to run?

My Projects --> Select any you want --> Save
I'm currently running HFCC and RICE (both of which get pretty good points, HPF2 and HCC didn't give the best PPD, and, at least in the case of HPF2, errored a lot for me so I don't run it anymore)
