12. Java > Concurrency

Concurrency

People talk a lot about the end of Moore’s Law, in that systems are getting wider but not necessarily faster. Do you agree?

James: Yeah. Moore’s Law was all about gate count, and it’s pretty easy to see how gate count has got a pretty good chance of growth in following Moore’s Law for a lot of years. But how that translates to clock rate, it’s almost been an accident that it’s been able to be interpreted as clock rate for so long.

Does the need for better concurrency change the implementation or also the design?

James: Oh, it changes the design of things tremendously, although there is a certain amount of variability as you go from problem domain to problem domain.
