DMTCP (Distributed MultiThreaded Checkpointing) 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.News | See Also | Authors | Acknowledgement
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. See contrib/infiniband/README for more details.
We are currently looking for well qualified applicants who are interested in joining a Ph.D. program in order to do research on checkpointing and reversible debugging. Interested applicants should write to Gene Cooperman (firstname.lastname@example.org) at Northeastern University.
DMTCP is currently maintained by Kapil Arya, Gene Cooperman, Rohan Garg, Jianun Cao, and Artem Polyakov. The list of active developers continues to evolve.
