Open MPI 1.2 Released

The Open MPI community announced yesterday the availability of Open MPI 1.2, which includes a number of bug fixes, feature enhancements, and performance improvements over 1.1.x versions of the library. Congratulations to the community, including Sun's MPI engineering team, for reaching this significant milestone!

Among the improvements cited by the community are:

  • Much improved MPI collective algorithms
  • General performance improvements throughout the entire code base
  • Much improved run-time support, particularly when dealing with error scenarios
  • Support for MPI-matching networks such as Myrinet MX and QLogic InfiniPath
  • New support for Sun platforms: Solaris, Sun Studio compilers, N1GE / Grid Engine resource managers, uDAPL networks
  • Tested with a variety of compilers on several platforms, including: GNU, Intel, Portland, Pathscale, Sun Studio
  • Improved support for heterogeneous execution environments to accommodate differences in CPU architectures and adapter capabilities

See the full announcement for a more complete list of changes.

Sun's supported MPI library for Solaris, based on Open MPI 1.2, is currently available via Sun's Early Access Program. The official release will be available soon.
