TOTALVIEW® DEBUGGER PORTED TO SICORTEX LINUX CLUSTER COMPUTERS

Industry-Leading Multi-Core Debugger Will Accelerate Application Development Time on SiCortex High-Performance Systems

Dresden, Germany- June 26, 2007 - TotalView Technologies, the world's leading provider of scaleable debugging and analysis software solutions for the multi-core age, today announced that it has ported its award-winning TotalView® debugger to run on SiCortex’s cluster computer systems. TotalView licenses and support will be available directly from SiCortex.

SiCortex’s line of ultra-low power, high-performance Linux computers represent a major breakthrough in cluster computing, enabling the proliferation of multi-teraflop computing to a wider range of users. By implementing a complete cluster node on a chip, including six 64-bit processor cores, multiple memory controllers, a high-performance cluster interconnect and a PCI Express connection to storage and internetworking, SiCortex’s computer systems dramatically reduce energy and infrastructure needs while delivering superior performance. A complete SiCortex cluster node with DDR-2 memory consumes only 15 watts of power, an order of magnitude less than the 250 watts used in a conventional cluster computer.

TotalView Technologies’ TotalView debugger, the world’s most advanced debugger, is powerful and easy-to-use, dramatically reducing debugging time and enhancing developer productivity. Built to handle the complexities of the world’s most demanding applications, TotalView is capable of scaling from one to thousands of processes or threads with applications distributed over multiple machines or processors. TotalView supports multiple platforms, compilers and programming languages.

“Developer productivity is an important focus for us,” said Dr. John Mucci, CEO of SiCortex. “With its unparalleled simplicity and power, TotalView is a natural complement to the compilers and performance analysis tools available in the SiCortex development environment.”

“SiCortex’s innovative approach to cluster computing is an exciting development in the HPC market,” said Rich Collier, CEO of TotalView Technologies. “We are delighted to partner with them to bring our debugging capabilities to their systems, which we believe will help expand the market even further.”

TotalView Technologies and SiCortex will be exhibiting at this week’s International Supercomputing Conference in Dresden, Germany. SiCortex will be in booth D02-D06 and TotalView Technologies in booth D08-D10.
