Code Optimization.
Description:
The optimized routines for copying regular hyperslabs in memory have been
using the same matrix routines to copy their hyperslab pieces as the
routines for irregularly shaped hyperslabs. This ends up imposing lots of
extra overhead on the optimized routine, since it basically "knows" all the
matrix information it needs.
Solution:
Keep track of the [small] amount of matrix information necessary to perform
the regular hyperslab copies in the optimized routines themselves instead of
using the matrix routines. This improves the performance for the benchmark
I'm running from ~18 seconds to ~12 seconds and should apply to parallel
I/O situations also.
Platforms tested:
Solaris 2.6 (i.e. baldric)

This is hdf5-1.3.31 currently under development
Please refer to the INSTALL file for installation instructions.
------------------------------------------------------------------------------
This release is almost fully functional for the entire API defined in the
documentation, see the RELEASE file in this directory for information
specific to this release of the library. The INSTALL file contains
instructions on compiling and installing the library. The INSTALL_parallel
file contains instructions on installing the parallel version of the
library.
Documentation for this release is in the html directory. Start with the
"index.html" in that dictectory.
Four mailing lists are currently set up for use with the HDF5
library.
hdf5 - For general discussion of the HDF5 library with
other users.
hdf5dev - For discussion of the HDF5 library development
with developers and other interested parties.
hdf5announce - For announcements of HDF5 related developments,
not a discussion list.
hdf5cvs - For checkin notices of code development on the library,
not a discussion list.
To subscribe to a list, send mail to "majordomo@ncsa.uiuc.edu",
with "subscribe <list>" in the _body_, not the Subject, of the message.
E.g., subscribe hdf5
Messages to be sent to the list should be sent to "<list>@ncsa.uiuc.edu".
Nearly daily code snapshots are now being provided at the following URL:
ftp://hdf.ncsa.uiuc.edu/pub/outgoing/hdf5/snapshots
Please read the readme file in that directory before working with a library
snapshot.
The HDF5 website is located at http://hdf.ncsa.uiuc.edu/HDF5/
Bugs should be reported to hdfhelp@ncsa.uiuc.edu.
