Linux, VMware, Win7?

post #1 of 14
Thread Starter 
I have a 24/7 Folder, specs;

Athlon x64 3800+ AM2
9800GT 512Mb
(pretty much all that's relevant)

It is currently running Win7 but I was wondering if I would see an increase in PPD if I ran either a VM or even just dual booted with a linux distro. I am fairly familiar with linux, just not in terms of folding.

I only fold on the GPU seeing as the CPU foldling SMP is just poop. Anyway, to restate the question, would I benefit from running linux when folding on the 9800GT alone? (~4500 PPD currently)

There is no performance gain in running GPU folding under Linux, just too much hassle and it takes some serious self control not go bash your rig with a hammer when you set it up.. And quite laggy too, if you get it running.

SMP sees a fair gain tho, 10-15% is what I've found out moving from W7 to VM.

Ahh alright, it seems my suspicions were correct then. I figured it wouldn't effect GPU folding much, but I figured id ask more experienced folders! Thanks!

GPU folding in linux requires a lot of cpu overhead due to having to use wine emulation. For example each 480 I have will max out a cpu core and still only get 12k ppd vs the 18k ppd it will get in windows while only using about 3% of a core. Linux is only worthwhile if you're doing pure bigadv with no gpu.

stren is correct there is no advantage to running a3 core on linux it is actually the opposite Windows out preforms Linux on the a3 core but when you talk about a5 and bigadv Linux is faster.

How come I see a gain going from SMP A3 in W7 to SMP A3 in a VM running Ubuntu, about 10% drop of TPF and almost 20% boost in PPD? That was measured on the same WU and the percentage too. Am I special?

Yes you are really special if you can run the same WU on Windows and Linux perhaps you can explain how to run a Windows WU on Linux or a Linux WU on Windows.

I use the 'queue.dat', 'wudata_xx.dat' and 'wuinfo_xx.dat' from one WU and let the client download the proper core, be it Win or Linux. This makes it easy to compare setups testing for stability and such. It was my understanding that these files are what identifies the WU, but maybe I'm mistaken?

It was prooven a long time ago that a3 was faster on Windows than it was on Linux and the a3 has not been changed it is still the same a3 core that it was a couple of years ago. And a Linux a3 WU will not run on Windows and a Windows a3 will not run on Linux at least not as far as my understanding. The a5 core is a different storey the Linux version is faster than Windows also the new a4 appears to be faster on Linux than Windows but that has not been confirmed yet.
