Qin Ling,

  Since the release of 0.4.2 in Oct 2005, the development on BLCR has 
been slow, but has not stopped.  There have been small changes 
(including bug fixes and support for newer kernels) since 0.4.2 which 
are available as "snapshot" releases at http://mantis.lbl.gov/blcr-dist/

  I am currently testing what will become 0.4.3, hopefully by the end of 
January, adding support for checkpointing entire process groups and/or 
sessions.  However, there are still bugs to be resolved before that release.

  As for "mpich support", the situation is slightly more complicated 
than that phrase implies.  The "support" goes in the MPI implementation, 
which must be modified to call BLCR to cooperate in checkpointing of 
communication.  LAM/MPI is *not* the only MPI implementation with 
support currently available.  The most recent release of MVAPICH (MPICH2 
ported to InfiniBand) has support as well.  The teams working on MPICH2 
and OpenMPI are both working on support - you should contact those 
groups if you want estimated availability dates.
