Retooling Algorithms
Charles Leiserson and his team are experts at designing parallel algorithms—including one for a chess-playing program that outperformed IBM’s Deep Blue.
From ACM News
The Next Operating System
Operating systems for multicore chips will need more information about their own performance—and more resources for addressing whatever problems arise.
