Hello, Traditionally, a parallel application is run like following >>> export FOO=foo >>> mpirun -np 2 -machinefile mymachinefile my_parallel_app [app options] (To be known by all the nodes of my cluster, the environment variable FOO has to be set on all the nodes or exported on the nodes by mpirun.) Few months ago, I used MVAPICH on a cluster of Opteron: this MPI distribution allows me to launch shell scripts with the mpirun script like following : myscript.sh | | #!/bin/bash | export FOO=foo | my_parallel_app [app options] | end >>> mpirun -np 2 myscript.sh(In that case, the environment variable FOO is exported on all the nodes) I heard all the distributions do not support this feature. Indeed, I use currently MPICH-1.2.5.2 which does not permit me to do it.Nevertheless, it should be standardized in the distributions based on the MPI-2 standard. So, can someone confirm it and/or send me a link to the page of the standard which says it? Thanks a lot, Mathieu. |
