IBM starts work on computer to rival the human brain
By Mark Henderson, Science Correspondent
The first supercomputers to approach and even surpass the processing power of the human brain are to be built by IBM, under a £184 million contract announced by the US Government yesterday.
ASCI Purple and Blue Gene/L will be the fastest and most powerful machines built, with a combined capacity equal to the 500 best of todays computers.
ASCI Purple, which will be built first and used to simulate nuclear tests, will be able to complete 100 thousand billion calculations per second a speed known as 100 teraflops that some scientists say is comparable to the human brain.
Blue Gene/L, which has a broader range of functions and will be used by US Department of Energys three main laboratories, will be more powerful still, with a maximum speed of 360 teraflops.
The computers, which will be built by 2004, will lack the consciousness, intellect and capacity for thought of a brain, but will be equivalent in calculating speed and power. They have memories of at least two petabytes equal to a billion books. Mike Nelson, IBMs director of internet technology and strategy, said: It is hard to quantify the power of a brain, but when you look at the raw processing power of these machines, youre looking at figures in the same ballpark.

Just think, in 10 years your PowerBook will be able to do 360 teraflops. Just think of the gaming possiblities...
