Does anyone know the floating-point operations per second for the RS/6000 used in "Deep Blue" vs. Kasparov 1997? I can't find it anywhere and would like to know so I have something for comparison. Another interesting article at: http://www.news.com/News/Item/0,4,19117,00.html This tells of plans to have a 100 teraflop machine in service by 2004. Peter
