Hello, I have Torque as the batch manager and Open MPI (1.0.1) as the MPI library. Initially I request for 'n' processors through Torque. After the Open MPI jobs starts, based on certain conditions, I want to acquire more processors outside of the initially assigned nodes by Torque. Is this a problem? Is this why my MPI_Comm_spawn is failing (where I say the MPI_Info element's key as "host" and value as the hostname of the new node outside of Torque's initial assignment)?
Any ideas? Thanks, Prakash
