Release 2.0.4 (unreleased)

Bug fixes:

  • Fix detection of GCC compiler with some Cray versions.

Changes:

  • Remove some definitions for some ancient compilers and MPI libraries.

  • Add ple_locator_exchange_point_var_all function to handle exchanges with both located and unlocated points.

  • Extend ple_coupling_mpi_set features:

    • Add ple_coupling_mpi_set_compute_timestep function to compute a recommended time step for the current application based on provided flags and values of applications in a set.
    • Add PLE_COUPLING_TS_FOLLOWER and PLE_COUPLING_TS_FOLLOWER synchronization flag defintitions for additional time step update schemes.

  • Remove libtool from build system. This requires slightly more commplex rules in the Makefile.am's, but should avoid issues on some systems where lbitool's absolute refusal to ignore .la files even when they contain incorrect values could cause more problems than it solves.

  • Add key/value-based settings functions:

    • ple_locator_set_default_option
    • ple_locator_set_options

Release 2.0.3 (November 8, 2021)

Changes:

  • Add communication ordering to reduce serialization in parallel. Algorithm versioning ensures this is not used when combined with an older PLE library version.

Bug fixes:

  • Fix PLE locator variable exchange in asynchronous reverse mode.

  • Really fix PLE locator for local cases when points fall outside domain.

  • Avoid crash in ple_locator_shift_location for empty locator.

Release 2.0.2 (March 16, 2018)

Bug fixes:

  • Fix in ple_locator_extend_search for non-local cases.

Changes:

  • Use asyncronous locator variable exchange by default when number of communicating ranks is not too large (< 128).

  • Implement handling of point tags so as to ignore location on elements sharing tag (also requires matching features in ple_mesh_elements_locate_t function used.

Architectural changes

  • Add support for internationalization.

Release 2.0.1 (May 21, 2015)

Bug fixes:

  • Fix in PLE locator indexing for ple_locator_extend_search.

Changes:

  • Improve Cray support.

Release 2.0.0 (April 30, 2015)

Changes:

  • Upgrade PLE API so as to allow multiple searches. This replaces the use of functions to locate closest elements, as using successive searches with increasing tolerance requires no specific function and is expected to have more stable behavior.

Release 1.0.4 (August 18, 2014)

Bug fixes:

  • Fix asynchronous exchange for ple_locator_exchange_point_var.

Changes:

  • Add Clang compiler detection.

  • Updates in build scripts and MPI detection.

Release 1.0.3 (April 03, 2013)

Bug fixes:

  • Fix a test for "locate on closest" and another for empty realloc.

Release 1.0.2 (October 29, 2012)

Bug fixes:

  • Fix extra count (should be 3, not 4) in PLE flags exchange in ple_locator.c.

  • Fixes for mixed "locate on closest / do not locate on closest" cases.

Changes:

  • Avoid deprecated MPI datatypes to prepare for MPI 3.

  • Improve robustness of MPI detection tests.

Release 1.0.1 (June 26, 2012)

Bug fixes:

  • Fix link problem in PLE unit tests.

  • Fix MPI autodetection on FEDORA systems.

Changes:

  • Use same FLAGS as parent Code_Saturne build.

  • Remove support for IRIX and Tru64 Unix, as these systems are now obsolete.

Release 1.0.0 (July 28, 2011)

  • Initial release of the "Parallel Location end Exchange" library, based on the separation of the related functionality from the "Finite Volume Mesh" library.
