Parallel applications can read files with metadata cache images, but since this is a collective operation, a deadlock is possible if one or more processes do not participate. Three tests fail with OpenMPI 3.0.0/GCC-7.2.0-2.29: testphdf5 (ecdsetw, selnone, cchunk1, cchunk3, cchunk4, and actualio) t_shapesame (sscontig2) t_pflush1/fails on exit The first two tests fail attempting collective writes. Known problems in previous releases can be found in the HISTORY*.txt files in the HDF5 source. Please report any new problems found to help@hdfgroup.org.
