Hi, I am observing following message on Windows platform...
c:\Users\oza\Desktop\test>mpirun -------------------------------------------------------------------------- orterun:executable-not-specified But I couldn't open the help file: C:\Users\hpcfan\Documents\OpenMPI\openmpi-1.5.3\installed-64\share\openmpi\help-orterun.txt: No such file or directory. Sorry! -------------------------------------------------------------------------- I copied pre-built installed "OpenMPI_v1.5.3-x64" directory into one Windows machine to another Windows machine. As discussed in some mailing-threads I also tried to set OPAL_PKGDATA and other OPAL_* environment variables, but still above message persist. Please suggest. Thank you in advance. -Hiral
