The New Science of Visual Analytics
When Jim Thomas set out to find new ways to deal with the mountains of information our society generates, he didn't just create a new organization, he created a new science. In this article we'll take a look at how the National Visualization and Analytics Center is transforming the problem of finding needles in haystacks into an opportunity for a more secure future.

Revaluating FPGAs for 64-bit Floating-Point Calculations
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.

NASA and SGI Join Petascale Fray
SGI's entry into the multi-petaflops sweepstakes began last week with its announcement of the Space Act Agreement. The agreement outlines a multi-year partnership between SGI, Intel and NASA, with the goal of deploying petascale supercomputing capabilities for the NASA Advanced Supercomputing facility at the Ames Research Center.

On the Edge
If you read just one HPCwire article this week, be sure to catch John West's profile of the National Visualization and Analytics Center. The center is developing visual analytic tools for the U.S. Department of Homeland Security. The work is particularly interesting because it fits into the category of "Edge HPC," Tabor Research's term for HPC that lies outside the traditional science and engineering realm.
