Dear all, I'm using OMPI 1.6.4 in a Torque-like environment. However, since there are modifications in Torque that prevent OMPI from spawning processes the way it does with MPI_COMM_SPAWN, I want to circumvent Torque and use plain ssh only.
So, I configured --without-tm and can successfully run mpiexec with -hostfile. Now I want to MPI_COMM_SPAWN using the hostfile info argument. I start with $ mpiexec -np 1 -hostfile hostfile_all ./spawn_parent where hostfile_all is a superset of hostfile_spawn which is provided in the info argument to MPI_COMM_SPAWN. The message I get is: -------------------------------------------------------------------------- All nodes which are allocated for this job are already filled. -------------------------------------------------------------------------- Any help on this is highly appreciated. Thank you. Sebastian
