[mvapich-discuss] errors when using MVAPICH on P4 Cluster@OSC

[Abhinav Vishnu]

Hi,

Glad to know that the simple program worked. Can you let us know,
whether you used the same set of machines, which you are trying to use
for your original program?

Also, i feel that since your MPI program worked, it is not an MVAPICH
issue.

The only reason i am using icpc is that a shared open source library i am using now can not be compiled and linked together with my MPI program when using mpicc or mpicxx. I am suspecting it is the major problem that cause the failure of my program. but i don't know how to fix it.

MPI will not do the copying of the shared library. I think you may want
to ask your sys admin about this.

Thanks again,
