ibd0 and ce0 have to be on the same network for this to work. Or said differently IP must be able to find a route between en0 and idb0. If those are on different private networks (like 192.168.1.x and 192.168.2.x) this will not work. Aurelien Le 11 janv. 08 à 16:05, Rolf Vandevaart a écrit

Try something similar to this mpirun -np 1 -mca btl self,tcp -mca btl_tcp_if_include en1 NetPIPE_3.6/ NPmpi : -np 1 -mca btl self,tcp -mca btl_tcp_if_include en0 NetPIPE_3.6/NPmpi You should then be able to specify a different if_include mask for you different processes. Aurelien Le 11

I have a setup which contains one set of machines with one nge and one e1000g network and of machines with two e1000g networks configured. I am planning a large run where all these computers will be occupied with one job and the mpi communication should only go over one specific network which is c
