The underwelming response to my question leaves me wondering:

Am I to gather that there are no CentOS FAH users here?

or

Am I to understand that none of the CentOS FAH users have a GPU that works with FAH?

  • Yes, I’m a CentOS Folder. I’m one of 3 or 4 currently active on Team CentOS

    However, I’ve been unable to get GPU folding working, so I just dedicate all six cores to it.

    You may want to ask your original question on the forums at the FAH site, also.

  • Hey Fred,

    Thanks for the tip. I googled the FAH Hardware Forum. They recommend the NVIDIA 970 or 960 as their first choice.

  • True. but it “should” work on Fermi chipsets or later, and it doesn’t for me. I may well have a configuration problem, but I drew the line at butchering my system configuration to find out, this is my personal workstation, at home, and I don’t wanna break it.

    (it tries, and tries, and tries to fold but takes some error or other, backs off, tries again, and again, and again.)

  • Hello all,

    I tried also to run a GPU queue with FAH and it seems that the client program needs a newer libc library than available in C6. The logs were not helpfull:

    09:33:52:WU00:FS01:Running FahCore: /usr/bin/FAHCoreWrapper

    I have discovered the real error only after manually running the command listed in logs with strace:

    I have to investigate if there is a alternate fahclient (older version maybe) which works in C6

    PS: I have seen that the FAH executable for cpu queue is statically linked:

    file /var/lib/fahclient/cores/web.stanford.edu/~pande/Linux/AMD64/Core_a4.fah/FahCore_a4
    /var/lib/fahclient/cores/web.stanford.edu/~pande/Linux/AMD64/Core_a4.fah/FahCore_a4: ELF
    64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, for GNU/Linux 2.6.15, stripped
