Hello all. I want to learn MPI and I've trying to setting up OMPI for first time on three nodes. My config above: Ubuntu server - master node: pruebaborja 2x Ubuntu Desktop - slaves node: clienteprueba clientepruebados 4 slots
Im running NFSv4 for sharing /home/mpiuser. I want to test a plain "Hello world"but I can't make it working successfully on node clienteprueba. This is the problem: mpiuser@pruebaborja:~$ mpirun -np 6 --hostfile .mpi_hostfile ./holamundo [clienteprueba:01993] [[64434,0], 2] -> [[64434,0],0] mca_oob_tcp_msg_send_handler: writev:failed: Bad file descriptor (9) [sd = 9] [clienteprueba:01993] [[64434,0], 2] routed:binomial: Connection to lifeline [[64434,0],0] lost However, with clientepruebados and pruebaborja only on my hostfile, it works: pruebaborja slots=1 clientepruebados slots=4 #clienteprueba slots=1 mpiuser@pruebaborja:~$ mpirun -np 6 --hostfile .mpi_hostfile ./holamundo Hola, mundo, soy pruebaborja: 0 de 6 Hola, mundo, soy pruebaborja: 5 de 6 Hola, mundo, soy clientepruebados: 1 de 6 Hola, mundo, soy clientepruebados: 2 de 6 Hola, mundo, soy clientepruebados: 3 de 6 Hola, mundo, soy clientepruebados: 4 de 6 I've checked the OMPI versions on the machines and it's the same. I can't understand why Im getting this error on clienteprueba; i've done the same config on clientepruebados and clienteprueba. Anyone could help me to solve this? Sorry for my english. Thanks in advance
