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:
singularity checkpoint start {container} {name}
singularity checkpoint exec {name} {program and options}
or singularity checkpoint run {name} {run options}
.
singularity checkpoint make {name}
.singularity checkpoint stop {name}
.More information is available on the wiki.
