The program runs fine but I get a lot of unexpected messages in between the result. ########################################## jean@n06:~/examples$ mpirun -np 2 --host n06 hello_c libibverbs: Fatal: couldn't read uverbs ABI version. -------------------------------------------------------------------------- [[11410,1],1]: A high-performance Open MPI point-to-point messaging module was unable to find any relevant network interfaces: Module: OpenFabrics (openib)   Host: n06 Another transport will be used instead, although this may result in lower performance. -------------------------------------------------------------------------- libibverbs: Fatal: couldn't read uverbs ABI version.
