[mvapich-discuss] poll_or_block_event

[Jacob Harvey]

Jonathan,

Thank you so much for your response. We are using mvapich2-1.4.1 and
this problem happens with all of the programs that we run in parallel
(right now just DL Poly and CPMD).

What do you mean by back trace for the process? I'm not familiar with that.

I'll definitely upgrade the version of mvapich but in the mean time
I'd like to narrow down where the problem is coming from. It seems odd
that the cluster would be running just fine a week ago and now its not
without anything really changing.

I've contacted OSC about the problem as well but I haven't heard
anything back yet.

Jacob
