Hi Chris, At this moment, CRIU can only checkpoint serial applications. It is an ongoing project so this may change in the future, but I am pretty confident that will remain like this in the short and middle terms. However, we are also working with the developers of DMTCP (http://dmtcp.sourceforge.net/) on the Slurm driver. It is almost finished, and a beta version is already being tested :) DMTCP can checkpoint parallel applications (I have tried MVAPICH, not sure if OpenMPI right now) and GPUs are in their roadmap too, so may be useful for you.
Anyway, I'll do a presentation on all this on the oncoming Slurm User Meeting, so in a few weeks a will hopefully produce a PDF with a full comparison among all them in terms of performance, requirements and integration with Slurm.
