Hello all, <br><br>Is there any comprehensive documentation about mpich2? <br><br>I want to learn which keys are allowed in MPI_comm_spawn. Is not there any documentation about these things? <br><br>I want to create more then one process at once on specific hosts. <br>
<br>If I run the programm with following code I can create two processes on core01<br> np=2; <br> MPI_Info_create( &info2 );<br> MPI_Info_set(info2, "host","core01");<br> MPI_Comm_spawn( "/demo2/./demo2", MPI_ARGV_NULL, np, info2, 0, MPI_COMM_WORLD, &intercomm, errcodes );<br>
<br>But I want to create each process in other core? Is is possible? I tried adding more then one core to info2 but it did not work : <br> MPI_Info_set(info2, "host","core01,core02");<br><br>I got he following error: Fatal error in MPI_Comm_spawn: Other MPI error, error stack<br>
<br>Can somebody help me please? <br><br>Kind Regards, <br>
