In this paper, we describe a compilation system that automates much of the process of performance tuning that is currently done manually by application programmers interested in high performance. Due to the growing complexity of accurate performance prediction, our system incorporates empirical techniques to execute variants of code segments with(More)
Summary form only given. We describe initial experiences with semiautomated performance tuning of a linear solver in LS-DYNA, a large, widely-used engineering application. Through a collection of tools supporting empirical optimization, we alleviate the burden of performance tuning for mapping today's complex software to increasingly complex hardware(More)
This paper describes initial experiences with semi-automated performance tuning of a sparse linear solver in LS-DYNA, a large, widely used engineering application. Through a collection of tools supporting empirical optimization, we alleviate the burden of performance tuning for mapping today’s sophisticated engineering software to increasingly complex(More)
Mobile WiMAX is a rapidly growing broadband wireless access technology based on IEEE 802.16e-2005 air-interface standards. It provides high-speed internet service anytime, anywhere, from anyone and any device with seamless mobility and the service is located between mobile phone and wireless LAN. For special activities purpose, we have developed Mobile(More)
In this paper, we describe a compilation system that automates much of the process of performance tuning that is currently done manually by application programmers interested in high performance. Our approach combines compiler models and heuristics with guided empirical search to take advantage of their complementary strengths. The models and heuristics(More)
