BILLERICA, Massachusetts, June 04, 2008 - CSP Inc. (NASDAQ: CSPI) MultiComputer Division, a leading supplier of rugged embedded clusters, announced that it has shipped production grade 3000 SERIES VXS blades and 10-Gigabit VXS switch modules to one of its largest FastCluster customers. The 3000 SERIES provides the computational power and clustering technology required for their Anti-Submarine Warfare (ASW) platforms.

"CSPI’s past performance delivering high quality products on schedule and our ability to accommodate long-term DOD supply and support requirements were significant factors in the selection process," said William E. Bent Jr., VP, and General Manager for the CSP Inc. MultiComputer Division.

CSPI is supplying the 3000 SERIES for evaluation and integration into their advanced ASW platforms where size, weight, and power are critical factors. Delivering exceptional performance, low power consumption, and low latency, the 3000 SERIES blades operate in a standard VXS backplane with the companion Myri-10G VXS Switch Module. This implementation integrates the latest AltiVec™ enabled Freescale 8641D dual-core PowerPC processor and Myricom’s 10-Gigabit clustering interconnect offering a five-fold bi-section bandwidth improvement over the previous generation while preserving the customer’s application software investment.

"The FastCluster Open Architecture provides a performance enhancing technology upgrade to our customer’s program, while reducing development cost," said Bernard Pelon Director of Product Research. "Beyond performance improvements, MPI message passing enables transparent migration from single-core to multi-core for application developers while leveraging the latest e600 superscalar RISC core of the MPC8641D and Myri-10G serial interconnect on VXS".

The 3000 SERIES Open Software stack supports Linux 2.6 SMP, VxWorks AMP, and VxWorks SMP modes of operation. MPI over Myri-10G provides a robust set of features including OS-bypass, overlapping I/O and computation, source-based routing, route dispersion, and cut-through switching to further reduce latencies and improve bi-section bandwidth. The 3000 SERIES software development environment includes support for Wind River's Workbench open device software development suite, and optimized signal processing libraries (VSIPL, ISSPL) for AltiVec.
