Code Improvement
Description:
Split the metadata accumulator code into two parts: one for allowing writes
of the accumulator buffer during reads (when the buffer is dirty and needs
to be flushed to disk in order to hold the new metadata being read in) and
another for only allowing writes of the buffer during writes.
This allows the MPI-I/O VFL driver to use the metadata accumulator (but
only during writes) and benefit from the reduced number of metadata I/O
operations that it brings.
Platforms tested:
IRIX64 6.5 (modi4) w/parallel
HDF5 version 1.5.30 currently under development
Please refer to the release_docs/INSTALL file for installation instructions.
------------------------------------------------------------------------------
This release is almost fully functional for the entire API defined in the
documentation, see the RELEASE.txt 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. The INSTALL* files can be found in the release_docs/ directory.
Documentation for this release is in the html directory. Start with the
"index.html" in that directory.
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.
