The biggest issue you may have is that gnu fortran does not support all the fortran constructs that all the others do. Most fortrans have supported the standard plus the DEC extentions. Gnu fortran does not quite get all the standards.Intel fortran does support them all, and I believe that portland

Just to be clear: what you are launching is an orted daemon, not your application process. Once the daemons are running, then we use them to launch the actual application process. So the issue here is with starting the daemons themselves. You might try adding "-mca plm_base_verbose 5 --debug-dae

Hi, I'm developing MPI support for XtreemOS (www.xtreemos.eu) so that an MPI program is managed as a single XtreemOS job. To manage all processes as a single XtreemOS job, I've developed the program xos-createProcess that plays the role of the rsh agent (replacing ssh/rsh) to start a process
