DMTCP for Singularity

In a world ravaged by compute tasks that just can't stop...

This plugin is a simple solution that integrates the long-running DMTCP project into Singularity, a containerization platform optimized for security and performance of HPC tasks.

This is just a simple plugin that may be installed in Singularity versions < 3.5 (will need a little reworking for newer versions). A description of how to work with plugins is discussed in the plugin's directory, but it is designed to be installed with the install.sh script, provided a Singularity build directory for generating the plugin files as an arg. A simple set of commands are then available:

1. Start a Singularity with singularity checkpoint start {container} {name}
   • This is designed to mirror instance starting.
2. Start the desired program with singularity checkpoint exec {name} {program and options} or singularity checkpoint run {name} {run options}.
   • Again, attempting to mirror the included commands.
3. To run a checkpoint, singularity checkpoint make {name}.
4. To run a checkpoint then stop the program and container instance, run singularity checkpoint stop {name}.
