    The normal case will evenutally be for our checkpoint/retart software to
    be integrated into the batch system on a machine (like PBS,
    LoadLeveller, etc.), so you'd use a utility like 'qstat' to get your
    job's ID, and then you could checkpoint/restart it with that ID.
    We are adding such support to the Scalable Software Systems system
    project's software:
    And we hope at some point to see OpenPBS support too (and support from
    commercial vendors).
