[OMPI users] Choosing the processor Id when spawning a process

Hi, I have to spawn a set of processes on multiple hosts, with my own mapping pattern, including processor ID, for example : * process 1 on cpu0 of host 1 * process 2 on cpu1 of host 1 * process 3 on cpu1 of host 1 * process 4 on cpu0 of host 2 * process 5 on cpu1 of host 2 I see that only the

[OMPI users] spawn on a cluster with 2 Ethernet interfaces

Hi, I have to spawn multiple slaves processes on a cluster, from a unique master process. The open mpi distribution I use is 1.1.2. I'm using a HP cluster, with 2 ethernet NICs on each machine. My problem was a freeze of master when calling mpi_call_spawn_multiple, and of slaves when calling

Gadget2 - I cannot attach it because it is not publicly available, runs perfectly fine on any number of processes on systems such as Solaris 10 - Sun CT6 gigabit, SUN CT5 and myrinet gm, IBM regatta .. Sorry to be so expansive ... When I run the code on 32 CPUs on openmpi, mx using the studio11
