Yes. As an OMPI developer, I have dozens of different OMPI installs on my cluster (for various stages of development and testing, etc.). The only real issue is to ensure that you set your PATH (and possibly LD_LIBRARY_PATH) correctly to point to the one that you want. If you use the --enable-mpirun-prefix-by-default configure option, then you don't need to worry about paths on the remote nodes. > I have > openmpi 1.3.2 working fine with gfortran but I cannot build openmpi > 1.4.1 with Absoft - I get this message from libtool: > > /bin/sh ../../../libtool --mode=compile /Applications/Absoft11.0/bin/ > f90 -I../../../ompi/include -I../../../ompi/include -p. -I. -I../../../ > ompi/mpi/f90 -lU77 -c -o mpi.lo mpi.f90 > libtool: compile: /Applications/Absoft11.0/bin/f90 -I../../../ompi/ > include -I../../../ompi/include -p. -I. -I../../../ompi/mpi/f90 -lU77 - > c mpi.f90 -o .libs/mpi.o > Can't find the absoft directory. > Please set the ABSOFT environment variable and try again. > make[4]: *** [mpi.lo] Error 1 > > Note that ABSOFT is properly set as in fact shown above on the first > line.

We just had another user on the list have a problem compiling because they were doing "sudo make all" instead of just "make all". I'm not sure what exactly happened, but "sudo make all" apparently had some weird side effects whereas "make all" did not. FWIW: Most users compile Open MPI as a non-privlidged user and then only use sudo to "make install". -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
