[mvapich-discuss] core dump on mpi_init with ofed 2

[Abhinav Vishnu]

Hi David,

Thanks for this information. With this information, i am speculating 
that it could be
a problem with the setup. I think following these steps may help us 
narrow down the
problem:

1. Are you able to run the Verbs level tests (ib_rdma_lat, ib_rdma_bw, 
etc) between the
two nodes?

2. Please check the path of the OFED libraries which you are linking to 
the compilation
script. I hope that you are recompiling your programs with your OFED 1.2 
MPI installation.

Please let us know the outcome of your experimentation.

Thanks,

:- Abhinav

> I'm using 1.0 beta, but the same problem is with 0.9.8, both p3 and the version that comes with ofed 1.2 release. I compiled using the make.mvapich2.ofa option. I haven't specified any environment variables. I didn't change any of the scripts, except to set PREFIX before compiling. I reproduced the problem with a trivial program running on 2 nodes. I didn't see the problem running on ethernet on 0.9.8.
