hi, Hi, 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 199.63.34.154,199.63.34.36 hello it gives following error "btl_tcp_endpoint.c:572:mca_btl_tcp_endpoint_complete_connect] connect() failed with errno=113" I am using openmpi-1.2 regards, Abhishek
