Performance Evaluation and Analysis Consortium End Station

To maximize the utility of Leadership Class systems, such as the Cray X1E, Cray XT3, and IBM BlueGene/L (BG/L), the performance community (performance tool developers, system and appliation performance evaluators, and performance optimization engineers) must understand how to use each system most efficiently. To further understanding of these high-end systems, this proposal is focusing on four primary goals: (1) update and extend performance evaluation of all systems using suites of both standard and custom micro, kernel, and application benchmarks; (2) continue to port performance tools to the BG/L, X1E, and XT3, making these available to high-end computing users, and further develop the tools so as to take into account the scale and unique features of the Leadership Class systems; (3) validate the effectiveness of performance prediction technologies, modifying them as necessary to improve their utility for predicting resource requirements for production runs on the Leadership Class systems; (4) analyze and help optimize current or candidate Leadership Class application codes.
