Hi,
I'm trying to run a simple pi program compiled using openmpi.
My command line and error message is
[mpiuser@Pebble-anoop ~]$ mpirun -n 2 -hostfile /opt/openmpi/openmpi/
etc/openmpi-default-hostfile /home/mpiuser/cpi2
Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR)
Failing at addr:0x6

The application was compiled with the following command line
[root@Pebble-anoop examples]# mpicc -o cpi2 cpi.c
There are 2 single processor machines in the cluster with my host
file reading
pebble-anoop.local
compute-0-0.local
Finally, openMPI was compiled with no special options. Just the
default make all install.
Can someone help me? I'm a newbie at this: so please excuse my
naivete, and I'd be grateful if someone can point me in the right
direction.
Thanks,
Anoop
