LAM is pretty much in support mode these days; there is no one
actively working on it. We've all moved on and are working on Open
MPI these days (www.open-mpi.org).
Open MPI v1.3 was just released with BLCR support -- would it be
possible for you to try that?
There are a few bug fixes coming in 1.3.1, but Josh (the main
checkpoint/restart author in Open MPI) tells me that it's still quite
usable in 1.3.0.
