Understanding throughput-oriented architectures

November 24th, 2010

Abstract:

For workloads with abundant parallelism, GPUs deliver higher peak computational throughput than latency-oriented CPUs. Key insights of this article: Throughput-oriented processors tackle problems where parallelism is abundant, yielding design decisions different from more traditional latency oriented processors. Due to their design, programming throughput-oriented processors requires much more emphasis on parallelism and scalability than programming sequential processors. GPUs are the leading exemplars of modern throughput-oriented architecture, providing a ubiquitous commodity platform for exploring throughput-oriented programming.
