- RELEASE INFORMATION FOR PARALLEL HDF5
- -------------------------------------
+Operating systems listed below with compiler information and MPI library, if

+ Platform Information Comment
+ -------- ---------- --------
+
+ AIX 4.3.2 (IBM SP)
-* The comm and info arguments of H5Cset_mpi are not used. All parallel
- I/O are done via MPI_COMM_WORLD. Access_mode for H5Cset_mpi can be
- H5ACC_INDEPENDENT only.
+ FreeBSD 3.2 gcc 2.8.1
-* This release of parallel HDF5 has been tested on IBM SP2 and SGI
- Origin 2000 systems. It uses the ROMIO version of MPIO interface
- for parallel I/O supports.

-* Some to-do items for future releases
- support for Intel Teraflop platform.
- support for unlimited dimension datasets.
- support for file access via a communicator besides MPI_COMM_WORLD.
- support for collective access to datasets.
- support for independent create/open of datasets.
