The issue was exposed by a new test in the parallel + HDF5 test suite, but had existed before that. We believe the problem lies with + certain MPI implementations and/or filesystems. + + We have provided a pure MPI test program, as well as a standalone HDF5 + program, that can be used to determine if this is an issue on your system. + They should be run across multiple nodes with a varying number of processes. + These programs can be found at: + http://www.hdfgroup.org/ftp/HDF5/examples/known_problems/ + * Parallel mode in AIX will fail some of the testcheck_version.sh tests where it treats "exit(134) the same as if process 0 had received an abort signal. This is fixed and will be available in the next release. AKC - 2009/11/3 |
