Deep Blue Junior
IBM Deep Blue Junior (DBjr.) is a portable version of IBM's advanced chess
technology, Deep Blue. Deep Blue is the system which successfully played
against Chess Grand Master Garry Kasparov in early 1996. Since DBjr. is a
traveling version of Deep Blue, it is not nearly as strong as Deep Blue.
However, it is still a very powerful opponent. There are several fundamental
technology differences between Deep Blue and DBjr. Deep Blue uses
parallelized software running on a 32-node RS/6000 SP* supercomputer. It has 16
specialized chess accelerator chips running on each node (a total of 512 accelerator
chips) which boost its powerful performance. DBjr. is based on a single-node
RS/6000 workstation, and uses a total of 16 chess accelerator chips. DB jr. also runs
in a non-parallelized (serial) mode, meaning it does not divide the processing
work up between processors; all of the calculations are done on a single
processor. Using its 512 chips, Deep Blue examines and evaluates chess
positions at a high rate of speed -- at an average of 200 million chess
positions per second. DBjr., with 16 of the same silicon chess accelerator
chips, is capable of examining an average of 10 million chess positions per
second. This configuration means that Deep Blue is ten times faster than
DBjr.
Even in this scaled-down form, DBjr. performs at the level of a Grandmaster
player and has played very successfully against many formidable opponents.
Using many of the same technology innovations of Deep Blue, and developed
by the same IBM Research team, DBjr. has tested to be far superior than most other
chess computers, with the exception of Deep Blue.
