< | The software [http://dmtcp.sourceforge.net/ DMTCP] (Distributed Multithreaded CheckPointing) permits checkpointing of programs without having to recompile them. The initial execution is done with the program <tt>dmtcp_launch</tt> and specifying the checkpoint intervals. The restart can then be carried out by running the script <tt>dmtcp_restart_script.sh</tt>. By default, this script and the checkpoint files are written in the directory where the program was started. You can modify the location of these checkpoint files with the option <tt>--ckptdir <checkpoint directory></tt>. You can run <tt>dmtcp_launch --help</tt> to see all the options for DMTCP. Note that for the moment DMTCP does not work with software parallelized using MPI. | ||
