I have been trying to run some computations on our cluster (peloton2) that involve resuming from a checkpoint and have been seeing some bizarre behavior where chunks assigned to different mpi processes appear to be swapped. I’ve attached a visualization file from immediately after the computation resumes. I am not sure yet whether the processor chunks are actually swapped in the solution or just in the visualization output. I write my visualization files in hdf5, which I know is less common among aspect useres but I have found that these files are much easier to manipulate and postprocess using matlab and python. Is this a known issue, and do you have any ideas about how to go about debugging the problem?
I am using aspect 2.2.0-pre (8ff16a9f5)
deal.ii 9.2.0-pre (78d1660594)
