That is an awfully old kernel, so it may indeed not have support for binding. I'd have to defer to someone more knowledgable to say for sure, but you might consider updating to something newer. On Mar 17, 2011, at 1:57 PM, vaibhav dutt wrote: > 2.6.9-78.0.17.ELpapismp #1 SMP Tue Apr 7 13:14:04

The error is telling you that your OS doesn't support queries telling us what cores are on which sockets, so we can't perform a "bind to socket" operation. You can probably still "bind to core", so if you know what cores are in which sockets, then you could use the rank_file mapper to assign pro
