Hi, I am trying to run the example applications in OpenMPI using the command "mpirun --prefix /usr/local/ --mca btl_openib_cpc_include rdmacm -np 4 -H <IP> hello_c"
But I am getting the below warning "WARNING: No preset parameters were found for the device that Open MPI detected:" Also at the end (just before the above command returns), I see messages like "[localhost.localdomain:28537] 3 more processes have sent help message help-mpi-btl-openib.txt / no device params found [localhost.localdomain:28537] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages" Am I missing anything with the command that I used (OR) can we ignore these messages ? Please suggest me. Thanks & Regards, Ramu
