Where will all the threads come from?

Abstract

Today, multicore microprocessors are at the heart of systems ranging from laptops to supercomputers. The shift to multicore architectures has transformed the problem of improving program performance from a micro-architecture problem to a software problem, shifting the focus from instruction-level parallelism to thread-level parallelism. As the density of transistors on chips increases, technology roadmaps call for increasing the number of cores. A key challenge facing the community is how we will keep increasing numbers of cores busy with productive work. Of great interest are answers to the question, "Where will all the threads come from"
