This is a nice overview of parallel computing with Beowulf:
"Andrew Blais introduces the concept of Beouwulf clusters, which extensively reduce the time to process software by using multiple CPUs executing program fragments in parallel under Linux or NT. He describes various implementations, the relative performance of the clusters, and the technology needed to make them effective."
Will face recognition be the Patriot missile of the domestic fight against terrorism--a technology that initially draws raves but ultimately doesn't work as well as billed?
Facial recognition involves using computers to scan a picture--like those from security cameras at an airport--and then searching through a database of other pictures for matches.
