In general, it is pretty straightforward to port OMPI to a new environment, assuming you just want TCP transport for MPI. In fact, if you can use ssh to launch things and a hostfile to tell ORTE where to put the procs, then no porting may be required. Have you tried simply building OMPI in that environment and running it? Given that OpenVMS is now Posix compliant, it may just work. > > Any information would be useful. > > Regards > Vladimir Yumashev > Assoc.Prof. > Moscow Inst. of Physics & Technology (MFTI) > +7-495-556-6554 > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users
