Airborne Laser
The Boeing-led Airborne Laser team exposes the Airborne Laser's conformal window during a test flight. Such an exposure is necessary for the weapon system to complete its mission of shooting down a ballistic missile during the boost phase of flight.
Beowulf (computing)
(Redirected from Beowulf cluster)
The Borg, a 52-node Beowulf cluster used by the McGill University pulsar group to search for pulsations from binary pulsars.

Beowulf is a design for high-performance parallel computing clusters on inexpensive personal computer hardware. Originally developed by Donald Becker at NASA, Beowulf systems are now deployed worldwide, chiefly in support of scientific computing.
A Beowulf cluster is a group of usually identical PC computers running a FOSS Unix-like operating system, such as Linux or BSD. They are networked into a small TCP/IP LAN, and have libraries and programs installed which allow processing to be shared among them.
There is no particular piece of software that defines a cluster as a Beowulf. Commonly used parallel processing libraries include MPI (Message Passing Interface) and PVM (Parallel Virtual Machine). Both of these permit the programmer to divide a task among a group of networked computers, and recollect the results of processing.
The name comes from the legend of Beowulf.
