Sun Studio Express 11/08 + Shanghai server module = new SPEComp World Record
Sun's newest blade, Sun Blade X6440, server module powered by the latest Quad-Core AMD Opteron processors code-named "Shanghai" posted the best x86 16-thread result on the prominent HPC SPECompM2001 benchmark with the newly released Sun Studio Express 11/08 compilers on OpenSolaris 2008.05. SPEComp is often used as a barometer of performance for shared memory compute-intensive scientific applications, so this is a great announcement during the ongoing Supercomputing 2008.conference.
The Blade server module was announced as part of Sun's Technology Demos highlighting a new Open Petascale computing environment called the Sun Constellation.

Sun Blade X6440 (4 x AMD Opteron 8384 chips, 16 cores, 4 cores/chip, 16 threads) SPECompM2001 - 35,896.

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
