Most of my previous messages in this thread were related to having to
run multiple distributions to cater for the needs of specific
application software which would not run or would not be supported if
run on a distribution other than the one specified by the ISV.
The question of interconnect which limits running of specific software
is a similar, but different question. I also had to deal with software
that uses f.e. GlobalArrays/ARMCI for which only GM but not MX is
supported on Myrinet cards.

Yes, this is already in use here for some time.

Different libraries is partly covered already when talking about
different distributions. Different compilers... hmm, I don't want to
start on this subject, I've already written enough in this thread :-)
But can f.e. someone shed some light as to why PathScale compilers are
not supported on Debian or Ubuntu (LTS) ?
