The Future of the Parallelism and its Challenges

Research and education in Parallel computing technologies is more important than ever. Here I present a perspective on the past contributions, current status, and future direction of the parallelism technologies.

While machine power will grow impressively, increased parallelism, rather than clock rate, will be driving force in computing in the foreseeable future. This ongoing shift toward parallel architectural paradigms is one of the greatest challenges for the microprocessor and software industries. In 2005, Justin Ratter, chief technology officer of Intel Corporation, said ‘We are at the cusp of a transition to multicore, multithreaded architectures, and we still have not demonstrated the ease of programming the move will require…’
