Hello.
Is there any way to automatically checkpoint/restart an application in
OpenMPI? This is, checkpointing the application without using the command
ompi-checkpoint, perhaps via a function call in the application's code itself.
The same with the restart after a failure.

Hi Amjad, list
HPL has some quirks to install, as I just found out.
It can be done, though.
I had used a precompiled version of HPL on my Rocks cluster before,
but that version is no longer being distributed, unfortunately.
Go to the HPL "setup" directory,
and run the script "make_generic".
This
Yes, it should - at least, for the more common environments (e.g., ssh).

Afraid there really isn't anything in the 1.2.x series - we set
several MPI-specific envars beginning with 1.3.0, but not in the older
releases.
The problem with using something like OMPI_MCA_ns_nds_vpid is that we
are free to change/eliminate it at any time - in fact, you won't find
that
How do I determine my rank in a shell script under OpenMPI 1.2?
The only thing I've found that looks promising is the environment
variable OMPI_MCA_ns_nds_vpid, and earlier discussion on this list said
that was for "internal use only".
I'm on Debian Lenny, which just relased with openmpi 1.2.7~rc2
I'm afraid this is a more extensive rewrite than I had hoped - the revisions
are most unlikely to make it for 1.3.2. Looks like it will be 1.3.3 at the
earliest.

Hi Ankush,
You can get some example MPI programs from http://www.pdc.kth.se/training/Tutor/MPI/Templates/index-frame.html
.
You can compare the performance of these in a MPI (single processor,
multiple processors) setting and non-MPI (serial) setting to show how
it can help their research.

Hi Ankush
Please read the FAQ I sent you in the previous message.
That is the answer to your repeated question.
OpenMPI (and all MPIs that I know of) requires passwordless connections.
Your program fails because you didn't setup that.
If it worked with a single compute node,
that was most likely
Me too, sorry, it definately seems like a bug. Somewere in the code probably
undefined variable.
I just never tested this code with such "bizzare" command line :)

If you configured OpenMPI with --prefix=/some/dir they are
in /some/dir/lib and /some/dir/include,
whereas the executables (mpicc, mpiexec, etc) are in /some/dir/bin.
Otherwise OpenMPI defa
Thanks,
I am not in a hurry but it would be nice if I could benefit from this
feature in the next release.

Honestly haven't had time to look at it yet - hopefully in the next
couple of days...
Sorry for delay
