Re: [ptp-user] mpich viability?
|
Hi Justin,
MPICH2 is supported for application launching/monitoring in PTP 1.1.
It's just debugging that is not supported. Also, there are a couple
of caveats. The MPICH2 proxy uses undocumented interfaces in the
mpd's, so you need to use the exact version of MPICH2 described on
the installation page. Support for other versions will probably
require changes to the proxy. Also, MPICH support has not been very
thoroughly tested, so I expect there will be bugs.
I'm hoping there will be better MPICH support in PTP 2.0, but it will
probably require someone to step up and do the work.
Regards,
Greg

Hello,
I've been tasked with testing your tools on some Cray systems, but
we are
currently using MPICH as our primary MPI library. OpenMPI has
support for
Catamount, but I will not be testing on that particular platform.
So I'm at a
dilemma.
I was curious if MPICH support was viable for your current system?
This would
include all tools that require OpenMPI at the moment
I've found a note or two referencing OpenMPI's runtime model. And I
understand
that you make significant use of that, but I was still wondering if
MPICH
support was being planned on / worked on. I'd be interested in
looking into
any beta stuff as well if it exists.
I haven't found any solid information on this in the archive or
searching so I
was hoping you could provide me with some information, if any.
Thanks,
Justin
