It at least shouldn't fail like that; set_atomicity doesn't return an error (which the test is prepared for on a filesystem like pvfs2). I assume doing nothing, but appearing to, can lead to corrupt data, and I'm surprised that isn't being seen already. HDF5 requires atomicity -- at least to pass its tests -- so presumably anyone like us who needs it should use something mpich-based with recent or old romio, and that sounds like most general HPC systems. Am I missing something? With the current romio everything I tried worked, but we don't get that option with openmpi.
