Title:  Exploring the Tradeoffs Between Performance and Power for Parallel Applications


The demand for computational power continues to drive the deployment of ever-growing parallel systems. Production parallel systems with hundreds of thousands of components are being designed and deployed. Future parallel systems are expected to have millions of processors and hundreds of millions of cores, with power requirements. The complexity of these systems is increasing, with hierarchically configured manycore processors and accelerators, together with a deep and complex memory hierarchy. As a result of the complexity, applications face an enormous challenge in exploiting the necessary parameters for efficient execution. While reducing execution time is still the major objective for high-performance computing, future systems and applications will have additional power requirements that represent a multidimensional tuning challenge. To embrace these key challenges, we must understand the complicated tradeoffs among runtime and power, and in some cases resilience strategies. This talk will present our methods and analyses to explore these tradeoffs for parallel applications.


Valerie Taylor is the Director of the Mathematics and Computer Science Division at Argonne National Laboratory. Prior to joining Argonne, she was the Senior Associate Dean of Academic Affairs in the College of Engineering and a Regents Professor and the Royce E. Wisenbaker Professor in the Department of Computer Science and Engineering at Texas A&M University. In 2003, she joined Texas A&M University as the Department Head of CSE, where she remained in that position until 2011. Prior to joining Texas A&M, Valerie Taylor was a member of the faculty in the EECS Department at Northwestern University for eleven years. Her research is in the area of high-performance computing, with a focus on performance analysis and modeling of parallel, scientific applications. She is also the CEO and President of the Center for Minorities and People with Disabilities in IT (CMD-IT). Valerie Taylor is an IEEE Fellow and an ACM Fellow.
