MultiThreading on CentOS

[performancefreak]

Hi Everyone,

First, I can't seem to view the Other Platform page on Folding at Home home page. So I can't download the latest client. I am using CentOS and Firefox 10.0.7. But I found I can go to the Older versions page. So I installed v6.

Does version 7 have any performance benefits over version 6? Is support for v6 going away soon?

Also, how do I make use of Intel P4's multi-threading? I have 2 machines that are have MT. Do I just open 2 terminals and run 2 sessions of FAH client?

Welcome to the forum performancefreak!

How strange that you can't see it. I think your Javascript isn't working or something. Try this alternate page: https://fah-web.stanford.edu/projects/F ... etaRelease

Development has stopped on v6. V7 aims to be better than v6, both for usability and scientifically. V7 supports the latest FahCores (the software that does the actual calculations) and can better interface with them. V7 should automatically detect multiple cores and then use all of them.

Hi Jesse_V,

Thanks for the link, I have downloaded the latest client.

It seems that Multi Threadiing is not supported, only multiple cores. Oh well.

Sorry for not being more clear. Some FahCores are multithreaded (such as the A4 core) so they can utilize multiple CPU cores. Is V7 not utilizing all your CPU cores?

On my Ubuntu system, V7 does support all threads presented to the OS by the hardware. I'm running SMP:8 on an i7 which has 4 cores/8 threads and it's running somewhat faster than if I were only using the 4 cores that some call "real cores" (which really means the FPU/math coprocessor hardware) rather than the 8 threads that some call "virtual cores" that have to share a FPU.
