The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 1.2.9. This release is mainly a bug fix release over the v1.2.8 release. This is the last planned release from the 1.2 series.
We strongly recommend that all users upgrade to the 1.3 series if possible. Version 1.2.9 can be downloaded from the main Open MPI web site or any of its mirrors (mirrors will be updating shortly). Here is a list of changes in v1.2.9 as compared to v1.2.8: - Fix a segfault when using one-sided communications on some forms of derived datatypes. Thanks to Dorian Krause for reporting the bug. See #1715. - Fix an alignment problem affecting one-sided communications on some architectures (e.g., SPARC64). See #1738. - Fix compilation on Solaris when thread support is enabled in Open MPI (e.g., when using --with-threads). See #1736. - Correctly take into account the MTU that an OpenFabrics device port is using. See #1722 and https://bugs.openfabrics.org/show_bug.cgi?id=1369. - Fix two datatype engine bugs. See #1677.
