Partnership brings HPC capability and 10GbE Interoperability to Embedded Cluster Computing

BILLERICA, Massachusetts, October 24, 2005 - CSP Inc. (NASDAQ: CSPI) MultiComputer Division, a leading supplier of rugged embedded clusters, announced today its selection of Myricom, Inc.'s Myri-10G technologies to power its next generation of systems. In close partnership with Myricom, CSPI will integrate the Myri-10G chipset, Myrinet Express (MX) and MPI/MX open software stack into its rugged embedded Linux FastCluster. Combining CSPI's experience in high performance embedded computing with Myricom's new 10-Gigabit Ethernet clustering technology offers an advanced Open Architecture for DOD programs requiring scalable platforms in harsh environments.

"Through our long-term strategic relationship with Myricom we are able to offer our FastCluster customers a dramatic tenfold improvement in backplane interconnect performance as well as broader interoperability with other 10-Gigabit Ethernet systems," stated Alexander R. Lupinetti, Chairman, President, and Chief Executive Officer of CSP, Inc.

The selection of the Myri-10G solution extends a ten-year working relationship between CSPI and Myricom that includes pioneering DARPA's vision for HPEC deployable open platforms based upon MPI (Message Passing Interface). The new Myri-10G technology will find its way into FastCluster blades that will start reaching the market by the second half of 2006.

"CSPI's deployment of our previous generation Myrinet-2000 interconnect in major DOD programs has been very successful both in system performance and in smooth development cycles," says Dr. Chuck Seitz, Myricom founder and CEO. "With the selection of Myri-10G for its next generation of high-density rugged clusters, we look forward to helping CSPI deliver new levels of performance in extremely demanding computational and physical environments."

The Myri-10G chipset and MX software leverage Myricom's experience as the leading global provider of high-performance cluster-interconnect technology. Myri-10G features a low power, high density, 16-port crossbar switch and a high-performance PCI Express (8 lanes) network processor, both with XAUI (IEEE 802.3ae) 10-Gigabit data rate physical layer interfaces to the switched fabric.

"Our FastCluster systems will benefit not only from the increased performance delivered by Myri-10G but from its robust set of features including OS-bypass, overlapping I/O and computation, source-based routing, route dispersion, cut-through switching, and the MX/Linux open-architecture advantage," said Bernard Pelon, Director of Product Research.

More advanced 2nd Generation FastCluster systems will be introduced later enabling dense and scalable embedded platforms with 100's to 1,000's of Multi-Core processing nodes delivering multi-teraflop capability in harsh environments where cooling, weight, power and size are critical.
