Hi, I am using 'snow' package on a Cray High Performance Computing System.

I got this error message '[NID 00030] 2012-02-27 01:48:28 Apid 304874:
Portals failed to handle copy-on-write.  Killing process' when my job is
done. The number of those error messages equals to the number of nodes the
job used, e.g. if the job used 4 nodes, there will be 4 error messages like
that. By setting variable MPICH_GNI_FORK_MODE = FULLCOPY, doesn't help.

Does anyone knows anything about it?

Thanks,
Libo
