You might want to try using the DVM (distributed virtual machine) mode in ORTE. You can start it on an allocation using the “orte-dvm” cmd, and then submit jobs to it with “mpirun --hnp <foo>”, where foo is either the contact info printed out by orte-dvm, or the name of the file you told orte-dvm to put that info in. You’ll need to take it from OMPI master at this point.
Alternatively, you can get just the DVM bits by downloading the PMIx Reference Server (https://github.com/pmix/pmix-reference-server <https://github.com/pmix/pmix-reference-server>). It’s just ORTE, but with it locked to the DVM operation. So a simple “psrvr” starts the machine, and then “prun” executes cmds (supports all the orterun options, doesn’t need to be told how to contact psrvr). Both will allow you to run serial as well as parallel codes (so long as they are built against OMPI master). We are working on providing cross-version PMIx support - at that time, you’ll be able to run OMPI v2.0 and above against either one as well.
