Change Log for libSplash

Release 1.2.4

Date: 2015-01-25

This release fixes a bug with parallel NULL reads.

Bug Fixes

  • Fix Null-Access Parallel Read Hang #148
  • Fix compile error on Red Hat #147

Release 1.2.3

Date: 2014-10-14

This release contains a minor fix for listing entries and groups.

Misc

  • Remove / from datasets when listing entries #143

Bug Fixes

  • Fix bug when querying DCGroup entries #142

Release 1.2.2

Date: 2014-06-21

That release was necessary since we forgot to bump the version number in <splash/version.hpp> with the last release.

Release 1.2.1

Date: 2014-06-20

This release contains a minor improvement in the data format. The internal format was increased to version 2.1 (which is backwards compatible to all 2.x formated files).

Misc

  • parallel simple data test re-enabled #130
  • data sets: use fixed size (non-extensible) by default, use H5F_UNLIMTED only in append mode #135
  • update install notes #134

Release 1.2.0

Date: 2014-04-30

New Features

  • splash2xdmf python script to create XDMF descriptions for libSplash files with domain information
  • allow to read/write attributes at groups

Interface Changes

  • major interface change: simplified interfaces as most read/write routines now use a Selection class for describe the source layout
  • local domain offsets are now exclusive, i.e. do not include the global domain offset
  • changed file format version to 2.0
  • add a finalize() call to ParallelDataCollector to free MPI resources

Bug Fixes

  • fix automatic chunking algorithm
  • only use HDF5 hyperslaps if necessary for improved performance
  • fix bug in getMaxID and getEntryIDs for ParallelDataCollector

Release 1.1.1

Date: 2014-02-20

Bug Fixes

  • Updated user manual for parallel I/O.
  • New tests and examples.

Interface Changes

  • Header files moved to splash subfolder (include/splash/splash.h).

Bug Fixes

  • Create duplicate of user-provided MPI communicator.
  • Allow empty write/read calls (no data).
  • Improved HDF5 detection in cmake file.
  • Fix usage of MPI data types.

Misc:

  • Compiling with OpenMPI now requires version 1.5.1 or higher
