The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 1.8.7.
v1.8.7 is a bug fix release, primarily driven by discovery of a significant memory leak. All users are encouraged to upgrade to v1.8.7 when possible. Version 1.8.7 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 v1.8.7 as compared to v1.8.6: 1.8.7 ---- ** NOTE: v1.8.7 technically breaks ABI with prior versions ** in the 1.8 series because it repairs two incorrect API ** signatures. However, users will only need to recompile ** if they were using those functions - which they couldn't ** have been, because the signatures were wrong :-) - Plugged a memory leak that impacted blocking sends - Fixed incorrect declaration for MPI_T_pvar_get_index and added missing return code MPI_T_INVALID_NAME. - Fixed an uninitialized variable in PMI2 support - Added new vendor part id for Mellanox ConnectX4-LX - Fixed NBC_Copy for legitimate zero-size messages - Fixed MPI_Win_post and MPI_Win_start for zero-size messages - Protect the OOB ports from segfaulting when accessed by port scanners - Fixed several Fortran typos - Fixed configure detection of XRC support - Fixed support for highly heterogeneous systems to avoid memory corruption when printing out the bindings
