[mpich-discuss] mpich2 hangs on Ubuntu beowulf cluster(with NFS) with patch

[Gustavo Correa]

Hi Konstantinos

It sounds as an ocean model code ...
Sometimes signal 11, segmentation fault, happens because of a small stack size.
Did you set the stack size on your compute nodes to a large value, or to unlimited?
You may need to ask the sys admin to change it in /etc/security/limits.conf.

I hope this helps,
Gus Correa
