Watson’s decisive win over two of Jeopardy’s top champions on national television earlier this year could turn out to be the most effective infomercial in the history of IT. Capitalizing on that accomplishment, IBM is working hard to highlight the supercomputing technology at every opportunity, including this week’s rollout of new and improved Power7-based servers.
New crop of Chinese supercomputers will feature homegrown chips.
In contrast to the previous decade, CPU clock rates are scaling slower over time due to the power constraints. However, the number of transistors per silicon area continue to increase roughly at the rate of Moore’s Law. Therefore, CPUs are being designed and built with an increasing number of cores, with each core executing one or more threads of instructions. This puts a new kind of pressure on the memory subsystem.
