It worked for me. 1. maybe mpirun belongs to another MPI. 2. try to define hosts ( -H host1,host2 ) Query#2: How can I include seperate exe file and have the IMB for it, e.g, > writing a hello.c with MPI elementary API calls, compiling with mpicc and > performing IMB for the same exe.? you have all the sorces maybe in IMB's README you can find something Best Regards, Lenny BR > > _______________________________________________ > devel mailing list > de...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/devel >
