Integrating Power and Cooling into Parallel Performance Analysis

Abstract

We present a new, integrated approach to parallel performance analysis that integrates traditional application-oriented performance data with measurements of the physical runtime environment. We have developed the needed infrastructure for combined evaluation of system, application, and machine room performance in the high end environment. We illustrate the utility of our approach, with data from our study of the power and cooling impact of the choice of physical location for an application within the machine room. We demonstrate the integration of measured performance data from the application, system, and physical room environment, and discuss the challenges encountered.
