I have migrated from LAM/MPI to OpenMPI. I am not able to execute simple
mpi code in which master sends an integer to slave.
If i execute code on single machine i.e start 2 instance on same machine
(mpirun -np 2 hello) this works fine.
If i execute in cluster using mpirun --prefix /usr/local -np 2
--host 22.214.171.124,126.96.36.199 hello
it gives following error
connect() failed with errno=113"
I am using openmpi-1.2
