Subject: Re: [OMPI users] Newbie question?

There was a bug in the code. So now I get this, which is correct but how
do I get rid of all these ABI, CMA, etc. messages?

$ mpiexec -n 4 ./a.out
librdmacm: couldn't read ABI version.

[[6110,1],1]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:

Module: OpenFabrics (openib)
  Host: elzbieta

Another transport will be used instead, although this may result in
lower performance.
