More Free HPC Developer Tools for Solaris and Linux

The Sun Studio team just released the latest version of our HPC developer tools with so many enhancements and additions it's hard to know where to start this blog entry. I suppose with the basics: As usual, all of the software is free. And available for both Solaris and Linux, specifically Solaris, OpenSolaris, RHEL, SuSE, and Ubuntu. Frankly, Sun would like to be your preferred provider for high-performance Fortran, C, and C++ compilers and tools. Given the performance and capabilities we deliver for HPC with Sun Studio, that seems a pretty reasonable goal to me. We think the price has been set correctly to achieve that as well. :-)

I have to admit to being confused by the naming convention for this release, but it goes something like this. The release is an EA (Early Access) version of Sun Studio 12 Update 1 -- the first major update to Sun Studio 12 since it was released in the summer of 2007. Since Sun Studio's latest and greatest bits are released every three months as part of the Express program, this release can also be called Sun Studio Express 3/09. Different names, same bits. Don't worry about it -- just focus on the fact that they make great compilers and tools. :-)

Regardless of what they call it, the release can be downloaded here. Take it for a spin and let the developers know what you think on the forum or file a request for enhancement (RFE) or a bug report here.

For the full list of new features, go here. For my personal list of favorite new features, read on.

  • Full OpenMP 3.0 compiler and tools support. For those not familiar, OpenMP is the industry standard for directives-based threaded application parallelization. Or, the answer to the question, "So how do I use all the cores and threads in my spiffy new multicore processor?"
  • ScaLAPACK 1.8 is now included in the Sun Performance Library! It works with Sun's MPI (Sun HPC ClusterTools), which is based on Open MPI 1.3. The Perflib team has also made significant performance enhancements to BLAS, LAPACK, and the FFT routines, including support for the latest Intel and AMD processors. Nice.
  • MPI performance analysis integrated into the Sun Performance Analyzer. Analyzer has been for years a kick-butt performance tool for single-process applications. It has now been extended to help MPI programmers deal with message-passing related performance problems.
  • Continued, aggressive attention paid to optimizing for the latest SPARC, Intel, and AMD processors. C, C++, and Fortran performance will all benefit from these changes.
  • A new standalone GUI debugger. Go ahead, graduate from printf() and try a real debugger. It won't bite.

As I mentioned above, full details on these new features and many, many more are all documented on this wiki page. And, again, the bits are here.
