You are right; HDF5 mandates calling H5Awrite from all processes:
http://www.hdfgroup.org/HDF5/doc/RM/CollectiveCalls.html
“Because raw data for an attribute is cached locally, all processes
must participate in order to guarantee that future H5Aread calls
return correct results on all processes.”
I will prepare a test case as well, to better understand this issue.
