CHELMSFORD, Mass., 6 April 2007. Mercury Computer Systems Inc. has released a binary distribution of its parallel acceleration system (PAS) middleware to high-performance embedded computing software initiative (HPEC-SI) members for use on a Georgia Tech Research Institute (GTRI) 64-node Linux cluster.

This development lab system is based on commercial-off-the-shelf (COTS) x86 computers. Members of the HPEC-SI working group are now evaluating PAS as middleware which allows straightforward migration of parallel vector signal image processing library++ (Parallel VSIPL++) implementations between benign environment workstations, parallel Linux clusters, and ruggedized, deployable multicomputer platforms.

PAS is Mercury's optimized middleware for data movement among compute nodes in scalable, high-performance embedded computing applications. The HPEC-SI distribution makes PAS available for non-Mercury hardware platforms for the first time.

The release implements PAS over standard TCP/IP to facilitate the easy migration of the PAS application programming interface (API) to a variety of target environments.

PAS is supported on all Mercury multicomputer system platforms and has been implemented to run on a variety of fabrics including RapidIO, InfiniBand, and Ethernet.

"Parallel VSIPL++ is a major step toward meeting the grand challenge of software development -- 'write-once, run-anywhere'. It is a breakthrough for C++ embedded developers, allowing them to code portable mathematical expressions," Eran Strod, director of product marketing for the defense business at Mercury, says.

Mercury plans to make a click-through license of the PAS Linux-x86 TCP/IP reference distribution available on its Web site.
