[PKGBUILD] foldingathome for SMP x86_64 clients

kozaki · 2006-11-22 20:08:27

I dunno wether such a post should go in Arch64 & Other Architectures or User Contributions? Because there's no specifically x86_64 topic on the 2nd, i guessed it should go in the 1st. Please correct me if I'm wrong.

Here comes a running PKGBUILD Folding@home SMP for dual/quad (or more) x86_64 cores
I just adapted Jason Taylor & seratne foldingathome's PKGBUILD as well as files that come with it.
Comments & corrections are welcome.

Please note this is a BETA release that is supposed to run only on SMP x86_64 CPUs.
On those machines it will allow greater improvments for the Folding@Home's project.
Please read the SMP FAQ carefully before running it.
Because it can run on x86_64 single core does not necessarily means it'd be usefull then. See this thread I opened on Folding-community.org's forum - SMP for Linux-64
