[mpich-discuss] Hydra torque support issues

I am using mvapich2-1.9a2 which is based of mpich2-1.5. We have enabled Torque integration with hydra. We are noticing an issue where in Torque is not tracking the resource used by the MPI application when they are built with mvapich2. Further investigation revealed that mvapich2 hydra process launcher was not setting the correct session id to what torque used for forking the shell. I am wondering if this is a known issue or something that has already been fixed. If it has been fixed, what would be the best way to upgrade just hydra without affecting the rest of MPI stack. -- Bharath
