Anant identified five significant areas where innovation had to occur for multicore processors to really take off. He addressed each of these areas. Here we discuss the interconnect bottleneck issues in further depth. SM: So you are doing some set of pre-routing on a switch. AA: Exactly. Now that you have a switch on each
Here we delve into a discussion of the differences between multiprocessor and multicore architectures. Multicore is when you put multiple processors on a single chip. But you still need to overcome bus bottlenecks. SM: So multicore does not use the traditional packaging? AA: Not really. In multiprocessors, for example, at Alewife we built a machine
