ABSTRACT:
This tutorial presents a practical approach to the performance modeling of large-scale scientific applications on high performance systems. The defining characteristic involves the description of a proven modeling approach, of full-blown scientific codes, that has been validated on systems containing 100,000’s of processors. We show how models are constructed and demonstrate how they are used to predict, explain, diagnose, and engineer application performance in existing or future codes and/or systems. Notably, our approach does not require the use of specific tools but rather is applicable across commonly used environments. Moreover, since our performance models are parametric in terms of machine and application characteristics, they imbue the user with the ability to “experiment ahead” with different system configurations or algorithms/coding strategies. Both will be demonstrated in studies emphasizing the application of these modeling techniques including: verifying system performance, comparison of large-scale systems, and examination of possible future systems.
