DMTCP is a tool to transparently checkpoint the state of multiple simultaneous applications, including multi-threaded and distributed applications. It operates directly on the user binary executable, without any Linux kernel modules or other kernel modifications.
Among the applications supported by DMTCP are Open MPI, 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). See the QUICK-START file for further details.
DMTCP supports the OFED API for InfiniBand on an experimental basis. For older versions of OFED, the DMTCP 2.1 release should be adequate. For newer versions of OFED, please use DMTCP 2.2.
To install DMTCP, see the file: INSTALL.

Directory layout:
- src : DMTCP source code.
- bin : DMTCP binaries (
dmtcp_launch,dmtcp_restart,dmtcp_coordinator, etc.) - lib : DMTCP internal libraries, including internal plugins that are not exposed to the end user.
- test : Used by 'make check'
- plugin : (top-level directory of optional plugins; they must be
invoked by a command line flag of
dmtcp_launch) - doc : Random documentation on aspects of the DMTCP design Note especially: doc/plugin-tutorial.pdf
- include : Contains dmtcp.h ; useful for third-party plugins
- contrib : Contributed plugins and other addons. The more popular ones will eventually be migrated to the top-level plugin directory as they become mature; Contrib plugins are not built by default
- util : random utilities useful mostly for experts
