Restart capability and remote executions make gnu parallel the tool if choice for HPC. For example, you might very well use gnu parallel to run 1000s of cpu-hours of numerical simulation using patterns such as these ones, https://docs.computecanada.ca/mediawiki/index.php?title=GNU_Parallel https://docs.computecanada.ca/mediawiki/index.php?title=GNU_... Using xargs for this kind of work is euhm... not a good idea.
