Modify the cache code (H5C) to support automatic cache resizing to adapt to the work load at run time. Description: Different applications require different sized caches to maintain an acceptable hit rate. This set of changes attempts to provide the ability to adjust to circumstances automatically. Solution: Added highly configurable code to allow the user to either set a fixed cache size, or allow the cache to grow and shrink according to conditions. If enabled, cache size increases are triggered when the hit rate drops below a user specified threshold in a user specified interval. Cache size reductions (if enabled) are triggered when either the hit rate exceeds some user specified threshold over a user specified interval, when the cache contains "enough" entries that haven't been accessed for a user specified interval, or some mix of the above. See the header comments on the H5C_auto_size_ctl_t structure in H5Cprivate.h for further details. At present, the cache resize configuration options are not accessible via the user API. Must add this. Platforms tested: h5committested, hepingi (serial), and copper (parallel) Misc. update: |

HDF5 version 1.7.45 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.
