Solaris HPC users can now get a free download of the latest Sun HPC ClusterTools 7.1. Sun HPC ClusterTools 7.1 is an update release based on Open MPI 1.2.4. Included in Sun HPC ClusterTools 7.1 is new Intel 32- and 64-bit support, improved parallel debugger support, PBS Pro validation, improved memory usage for communication, and other bug fixes by the Open MPI community since Open MPI 1.2 was first released.
…We are thinking about releasing a special HPC distro of Solaris that would come pre-configured with HPC ClusterTools, Sun Grid Engine, and Sun Studio. If you are interested, let me know via a comment.
