Big News for HPC Developers: More Free Stuff

'Tis the Season. Supercomputing season, that is. Every November the HPC community--users, researchers, and vendors--attend the world's biggest conference on HPC: Supercomputing. This year SC08 is being held in Austin Texas, to which I'll be flying in a few short hours.

As part of the seasonal rituals vendors often announce new products, showcase new technologies and generally strut their stuff at the show and even before the show in some cases. Sun is no exception as you will see if you visit our booth at the show and if you take note of two announcements we made today that should be seen as a Big Deal to HPC developers. The first concerns MPI and the second our Sun Studio developer tools.

The first announcement extends Sun's support of Open MPI to Linux with the release of ClusterTools 8.1. This is huge news for anyone looking for a pre-built and extensively tested version of Open MPI for RHEL 4 or 5, SLES 9 or 10, OpenSolaris, or Solaris 10. Support contracts are available for a fee if you need one, but you can download the CT 8.1 bits here for free and use them to your heart's content, no strings attached.

Here are some of the major features supported in ClusterTools 8.1:

  • 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

The second event was the release of Sun Studio Express 11/08, which among other enhancements adds complete support for the new OpenMP 3.0 specification, including tasking. If you are questing for ways to extract parallelism from your code to take advantage of multicore processors, you should be looking seriously at OpenMP. And you should do it with the Sun Studio suite, our free compilers and tools which really kick butt on OpenMP performance. You can download everything--the compilers, the debugger, the performance analyzer (including new MPI performance analysis support) and other tools for free from here. Solaris 10, OpenSolaris, and Linux (RHEL 5/SuSE 10/Ubuntu 8.04/CentOS 5.1) are all supported. That includes an extremely high-quality (and free) Fortran compiler among other goodies. (Is it sad that us HPC types still get a little giddy about Fortran? What can I say...)

The full list of capabilities in this Express release are too numerous to list here, so check out this feature list or visit the wiki.
