NB Kapil, would you be kind to clarify the relation/comparison?
i.e. like :
$> apt-cache show dmtcp
Maintainer: Kapil Arya <email@example.com>
Depends: libmtcp1, libc6 (>= 2.9), libgcc1 (>= 1:4.1.1), libstdc++6 (>= 4.2.1)
Description-en: Checkpoint/Restart functionality for Linux processes
DMTCP (Distributed MultiThreaded Checkpointing) is a tool to transparently
checkpointing the state of an arbitrary group of programs including
multi-threaded and distributed computations. It operates directly on the user
binary executable, with no Linux kernel modules or other kernel mods.
Among the applications supported by DMTCP are OpenMPI, MATLAB, Python, Perl,
and many programming languages and shell scripting languages. DMTCP also
supports GNU screen sessions, including vim/cscope and emacs. With the use of
TightVNC, it can also checkpoint and restart X-Window applications, as long
as they do not use extensions (e.g.: no OpenGL, no video).
