Hi guys,
This is my first foray into the world of OpenMPI (MPICH 1, 2 and LAM so far),
and I'm keen to test checkpointing using the BLCR kernel modules. I get the
BLCR components to build just fine (v0.8.1), but the OpenMPI build fails with:
% ./configure --with-blcr=/opt/blcr --with-blcr-lib
M C writes:

I think that the missing configure option might be the problem as
well. The BLCR configure logic checks to see if you have enabled
checkpoint/restart in Open MPI. If you haven't then it fails out of
configure (probably should print a better error message - I'll put
that on my todo list).
Hi Josh,
Yep, adding that "--with-ft=cr" flag did the trick. Thanks.
Cheers,

Is there a good reason why --with-blcr doesn't imply it?

Not really. Though it is most likely difficult to make it happen given
the configure logic in Open MPI

One thing to note in the mean time is that building with BLCR failed for
me with the PGI compiler with a link-time message about a bad file
format. I assume it's a libtool
