Sun ClusterTools 8.1 released


Sun ClusterTools 8.1 is Sun's high-performance MPI library and parallel job launcher based on Open MPI 1.3 . It is fully supported by Sun and includes all features introduced in CT 8.0 earlier this year (the first release to support Linux as well as Solaris), plus with 8.1 we have introduced additional MPI application profiling and Dtrace provider support, as well as key bugfixes.
Some of the significant features are:
  • Support for Linux (RHEL 4&5, SLES 9&10), Solaris 10, OpenSolaris
  • Support for Sun Studio compilers on Solaris and Linux, plus the GNU/gcc toolchain on Linux
  • MPI profiling support with Sun Studio Analyzer (see SSX 11.2008), plus support for VampirTrace and MPI PERUSE
  • Infiniband multi-rail support
  • Mellanox ConnectX Infiniband support
  • DTrace provider support on Solaris
  • Enhanced performance and scalability, including processor affinity support
  • Support for InfiniBand, GbE, 10GbE, and Myrinet interconnects
  • Plug-ins for Sun Grid Engine (SGE) and Portable Batch System (PBS)
  • Full MPI-2 standard compliance, including MPI I/O and one sided communication
