[svn-r4891] Purpose:
Code speedup Description: Chunking I/O routines are reading in an entire chunk when performing I/O on the chunk, even if the chunk will be too large to cache. Solution: If the chunk is too large to cache, uncompressed and has been allocated space in the file, or if we are using the MPI-I/O VFD, perform the I/O directly to the chunk, instead of reading the chunk into memory, updating it and immediately writing the entire chunk back out. Platforms tested: FreeBSD 4.5 (sleipnir) (using serial access) and IRIX64 6.5 (modi4) (using parallel access with MPI-I/O)
