Special Issue: Exploring the frontiers of computing science and technology: efficiently utilizing multicore and many-core processors

摘要

Multicore (e.g., Intel Westmere and IBM Power7) and many-core (e.g., NVIDIA Tesla and AMD FireStream graphics processing units (GPUs)) microprocessors are enabling more compute-intensive and data-intensive computation in desktop computers, clusters, and leadership supercomputers. However, efficient utilization of these microprocessors is still a very challenging issue. Their differing architectures require significantly different programming paradigms when adapting real-world applications. The actual porting costs are actively debated, as well as the relative performance between GPUs and CPUs.
