This research team is dedicated to furthering understanding and development of leadership-class compute systems Blue Gene/Q and XK7. Their work is focused on five goals: (1) develop new programming models and runtime systems for emerging and future-generation leadership computing platforms that exploit thread-level parallelism and potential architectural heterogeneity; (2) update and extend performance evaluation of all systems using suites of standard and custom micro, kernel, and application benchmarks; (3) continue to port performance tools and performance middleware to the BG/Q and XK7, make them available to high-end computing users, and further develop the tools and middleware to support the scale and unique modes of parallelism of each system; (4) validate and modify performance prediction technologies to improve utility for production runs on each system; and (5) analyze and help optimize current or prospective application codes and potentially develop new parallel algorithms.
