Hi,
I just spoke with our IB vendor and they seem to think its not a system
issue. I have also just compiled and installed openmpi on the cluster and I
am able to run the "cpi" test on any number of nodes I am also able to run
the pallas test suite on openmpi.
I would really like to get mvapich working on my cluster. Is there any way
that I can get mvapich to generate a more verbose output other than a "bus
error" message? I would like to get some type of debug info or message that
that might give me a better hint as to what might be the problem.
Thanks for any help on this.
Rene
