Hello,
I am developing a fortran mpi code and currently testing it on my
workstation,
so in a shared memory environment.
The (7 process) code runs correctly on my workstation using mpich2 (latest
stable version) & ifort 11.1, using intel-mpi & ifort 11.1, but
randomly hangs the
computer (vanilla ubuntu 9.10 kernel v. 2.6.31 ) to the point where only
a magic
sysrq combination can "save" me (i.e. reboot), when using
- openmpi 1.4.2 compiled from source with gcc, ifort for mpif90
- clustertools v. 8.2.1c distribution from sun/oracle, also based on
openmpi 1.4.2, using sun f90
for mpif90
I am prepared to do some testing if that can help, but don't know the
best way to identify what's going on.
I have found no useful information in the syslog files.
Regards, & thanks for the work on a great open source tool,
Olivier Marsden
