With compute nodes -its not easy. Even if they have X11 installed - you might have to do multiple things: 1. allocate nodes 2. create ssh-x11 tunnels to each node thats allocated [and hope its the same localhost:10 value] 3. Now start up the parallel job with this display mpiexec -n 4 ./ex2 -start_in_debugger -display localhost:10 Satish
