Revaluating FPGAs for 64-bit Floating-Point Calculations

May 14, 2008 | We now have generally available 2.5 GHz quad-core Opterons and Virtex-5 LX330, SX95T and recently announced SX240T FPGAs. In addition to this, Xilinx is releasing a new version of their floating-point cores that reduces the amount of logic and DSP slices needed for building floating-point function units. Taken together it is time to revisit Opteron floating-point performance versus FPGA performance.

Compilers and More: Accelerating High Performance

May 07, 2008 | Accelerators have been receiving a lot of attention lately from high performance computing users. PGI's Michael Wolfe thinks they should be getting even more. According to him, accelerators represent a more natural platform for HPC parallelism than either the current crop of general-purpose multicore chips or the ones on the drawing board. The trick is how to program them.

Intel and Cray Bring Collaboration Back to Supercomputing

Apr 28, 2008 | Intel and Cray have announced a partnership to begin collaboration on the design of a new supercomputer, which could be available in approximately three years. Under the partnership agreement, engineers from each company will work together directly, with the goal of generating a scalable architecture that will take unique advantage of next-generation Intel Xeon processors. Addison Snell, vice president and general manager of Tabor Research, explains how the two companies stand to benefit from the agreement.

Compilers and More: The Dangers of COTS Supercomputing

Apr 04, 2008 | Jack Dongarra (Univ. Tennessee and ORNL) says that the HPC ecosystem is out of balance; we've invested heavily in hardware development, and now we need to invest more heavily in software tools and methods to use the hardware. Rob Pennington (NCSA), said that the tools will appear when there are enough of these systems out there that the vendors can make money at it. PGI's Michael Wolfe disagrees with both these statements.
