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 MPI (various implementations), OpenMP, MATLAB, Python, Perl, R, 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. The OpenGL library for 3D graphics is supported through a special plugin.
DMTCP supports the commonly used OFED API for InfiniBand, as well as its integration with various implementations of MPI, and resource managers (e.g., SLURM).

Directory layout:
- src : DMTCP source code.
- src/plugin : source for DMTCP internal plugins.
- jalib : small pkg used by DMTCP for assertions, warnings, tracing code, etc.
- 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'
- test/plugin : Simple examples for learning DMTCP plugins
- 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 add-ons. 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
