high performance computing on graphics processing units: hgpu.org

This article presents the results of a research in applying modern Graphics Processing Units in the field of telecommunications. The most recent Wireless Local Area Network protocol, 802.11n, was studied, as it introduces a significant increase of computational complexity. Taking into consideration the concept of Software Defined Radio, the implementation of PHY algorithms was devised on a modern programmable 128-core GPU. It was shown that a significant performance increase could be obtained through applying this novel approach. Our experiments had shown more than 8x performance boost. The article also discusses the approach of utilizing a GPU as a networking device. The author shows how a GPU could be effectively used as a Digital Signal Processing unit of a real communication device.
