Linux SMP Client using only 80%

muhon_zen · Oct 29, 2009

Dear Folders!

Hello! I'm right now folding in my Dell Studio XPS 13. It folds good in Linux, using the SMP client. However, I stopped for a couple of days, then I didn't reach the deadline. Since it was late and I didn't know how to make the client download the new project, I kinda deleted the log files, the fah_cores and another bunch of files till it worked. It used to download 1800 point projects, but now it downloaded a 4000 point project.

Well, the problem is that now it seems to use only 80% of both cores, instead of the usual 100%. I'm measuring both in System Monitor and using gkrellm.

BTW, I'm using Ubuntu 9.04, x64 version.

Can anyone help me with this issue please?

EDIT: Removed the Screenshot.

Instead of huge screen shots, I suggest you copy and paste the log, wrapped in code tags particularly at the last client start before the issue occurred. As it is, you've missed the important stuff, like the start up arguments and the project number. There aren't any 1800 or 4000 point projects so it's a bit difficult to tell what happened, but I suspect you deleted client.cfg and either skipped config or forgot the -smp flag. It would be very helpful to see the last part of the log with the last restart and wouldn't hurt a thing if you deleted the screenshot while you were at it.

Another strong possibility is you downloaded an a1 core WU, which uses less resources than a2 core WUs. In that case, nothing is wrong at all.

I got an A1 SMP, used core 1.78 or somesuch, used ~85-90% of the cpu and was 200ppd short of an a2 2.10 core unit.

Sorry about the huge screenshot, It was really late and I thought it would actually generate a thumbnail. Anyways, I'll add the log tonight. I kinda remember doing the config, since it is still giving points to my user. HFM shows SMP-Gromacs so I guess it is working in SMP mode.

I'll keep you guys posted later. Thanks for replying.

Here's the log I promised

You're running normally. p5101 is an a1 core WU. A1 WUs don't use all the cpu cycles which is one of the reasons they are slower than a2 Wus. From time to time Linux rigs pick up a1 Wus. All is well.

muhon_zen · Oct 31, 2009

Thanks for answering. Yeah, I finished the WU and now it picked up the a2 core and worked perfectly.

Be happy you only got 1 A1 for the past 3 days, the only thing I'm getting are A1 workunits.
