WATSONArtificially intelligent computer systemCapable of answering questions posed in natural

languageDeveloped in IBM's DeepQA projectWatson was named after IBM's Thomas J. Watson.

Hardwareworkload optimized, integrating massively

parallel POWER7 processors and being built on IBM's DeepQA technology

composed of a cluster of ninety IBM Power 750 servers, each of which uses a 3.5 GHz POWER7 eight core processor, with four threads per core

In total, the system has 2,880 POWER7 processor cores and is able to store 16 terabytes of RAM

HardwareWatson can process 500 gigabytes, the

equivalent of a million books, per secondWatson's hardware cost at about $3 million

and with 80 TeraFLOPsthe content was stored in Watson's RAM for

the operation because data stored on hard drives are too slow to access

former winners Brad Rutterand Ken JenningsWatson received the first prize of $1 million

Watson – answering

Current ImplementationWatson software system's first commercial

application would be for utilization management decisions

Lung cancer treatment at Memorial Sloan–Kettering Cancer Center in conjunction with health insurance company WellPoint

IBM Watson’s business chief Manoj Saxena says that 90% of nurses in the field who use Watson now follow its guidance

Future ImplementationRensselaer Polytechnic Institute will receive

a successor version of Watsonat the Institute's technology park – for

researchers and students
