I have a small hostfile with the following two lines.
I get the following output from a small program when I set my
environment for openmpi-1.6.
tyr small_prog 106 mpiexec -hostfile hosts.openmpi_fulda -np 2 universe
number of processes: 2 universe size: 4
When I do the same for the last tarball of openmpi-1.9 I get the
following output so that "universe size" doesn't show the number of
available processors any longer.
tyr small_prog 108 mpiexec -hostfile hosts.openmpi_fulda -np 2 universe
number of processes: 2 universe size: 2
Have you changed the implementation so that this is intended? Thank you
very much for any answer in advance.
