Re: [mpich-discuss] MPI_init very slow with more than 3 nodes

It is possible there’s something really slow on your network. Just to eliminate MPI_INIT as a possible cause, can you try a non-MPI program: maybe /bin/true or /bin/hostname? % mpiexec -f fila5 -np 8 /bin/true — Pavan On Nov 28, 2013, at 8:10 AM, Bixente BODO GOMEZ <bixente.bodo(a)ehu.es> wrote: > Goods. > > I'm testing a mpich cluster (3.0.4) with 7 nodes quad core, Ubuntu 12.04.

Replace dot with slash. Looks like there is a confusion between "./examples.cpi", which does not exist, and "./examples/cpi", which does.

MPI_init very slow with more than 3 nodes
by Bixente BODO GOMEZ 28 Nov '13

28 Nov '13

Goods. I'm testing a mpich cluster (3.0.4) with 7 nodes quad core, Ubuntu 12.04. The master has the home directory and the nodes get it by nfs. I have change RPCNFSDCOUN from 8 to 64. The programs go fine with master and ONE of the other nodes, but when I start them with more nodes, MPI_Init (I think so) takes long time (~20 minutes). At these time in all nodes there is many network (read and write) and master's hard disk activity. For exemple: mpiu@u105251:~$ date; mpirun -f fila5 -np 8 test/hello; date mié nov 27 15:17:29 CET 2013 Hola desde el procesador u105251. 0 de 8 Hola desde el procesador u105251. 1 de 8 Hola desde el procesador u105251. 2 de 8 Hola desde el procesador u105251. 3 de 8 Hola desde el procesador u103972. 4 de 8 Hola desde el procesador u103972. 5 de 8 Hola desde el procesador u103972. 6 de 8 Hola desde el procesador u103972. 7 de 8 mié nov 27 15:17:30 CET 2013 mpiu@u105251:~$ date; mpirun -f fila5 -np 16 test/hello; date mié nov 27 15:17:39 CET 2013 Hola desde el procesador u105251. 2 de 16 Hola desde el procesador u105251. 0 de 16 Hola desde el procesador u105251. 1 de 16 Hola desde el procesador u105251. 3 de 16 Hola desde el procesador u103972. 4 de 16 Hola desde el procesador u103950. 8 de 16 Hola desde el procesador u103976.12 de 16 Hola desde el procesador u103972. 5 de 16 Hola desde el procesador u103950. 9 de 16 Hola desde el procesador u103976.13 de 16 Hola desde el procesador u103972. 7 de 16 Hola desde el procesador u103950.10 de 16 Hola desde el procesador u103976.14 de 16 Hola desde el procesador u103972. 6 de 16 Hola desde el procesador u103950.11 de 16 Hola desde el procesador u103976.15 de 16 mié nov 27 15:36:18 CET 2013 mpiu@u105251:~$ When the programs start, i.e. since the first C instrucction, they run fine. For that I think that the problem is MPI_init Anybody kowns why? Thank.

Is ./examples.cpi a valid binary for your platform? (Try the `file' command on it.) "No such file or directory" is, among other things, what you get when attempting to execute non-executables.
