QUESTION: Can I have multiple versions of HP-MPI installed and how can I
switch between them?
ANSWER
: You can install multiple HP-MPI’s and they can be installed
anywhere, as long as they are in the same place on each host you plan to
run on. You can switch between them by setting MPI_ROOT. See “General”
on page 295 for more information on MPI_ROOT.
QUESTION: How do I install in a non-standard location?
ANSWER: Two possibilities are:
% rpm --prefix=/wherever/you/want -ivh hpmpi-XXXXX.XXX.rpm
Or, you can basically "untar" an rpm using:
% rpm2cpio hpmpi-XXXXX.XXX.rpm|cpio -id
For Windows, see the Windows FAQ section.
QUESTION: How do I install a permanent license for HP-MPI?
ANSWER: You can install the permanent license on the server it was
generated for by running lmgrd -c <full path to license file>.
