Hello everybody,

Does anybody run FreeSurfer on Linux clusters in general or Scyld BeoWulf clusters in particular? Do you have any problems?

We are having some problems running FreeSurfer on our cluster. Quite often when we run autorecon2 stage on a compute node, it crashes. Sometimes a node crashes very quickly, sometimes after hours of processing. All of the 4 compute nodes that we have here have crashed. And it is not hardware related, because I ran linpack on them for 50+ hours in a row, and it was fine.

Any ideas what might be causing it? Any suggestions?

We run freesurfer-Linux-centos4_x86_64-stable-pub-v3.0.3-full.tar.gz version, and here is `uname –a` output:

Linux scyld.localdomain 2.4.21-37.EL.301r0072smp #1 SMP Wed Mar 1 04:09:49 EST 2006 x86_64 x86_64 x86_64 GNU/Linux

Thank you.

Regards,

Renat.
