Bug fix (sorta) Description: When the stride and block size of a hyperslab selection are equal, the blocks that are selected are contiguous in the dataset. Prior to my hyperslab optimizations, this situation used to be detected and somewhat optimized to improve performance. I've added more code to optimize for this situation and integrated it with the new hyperslab optimization that weren't very efficient for that case as they should have been. Solution: Detect contiguous hyperslab selections (i.e. block size in a dimension is the same as the stride in that dimension) and store the optimized, contiguous version of that hyperslab. We also store the original, un- optimized version of the hyperslab to give back to the user if they query the hyperslab selection they just made. Platforms tested: FreeBSD 4.1 |

RELEASE |
This is hdf5-1.3.30 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.
