“Energy Efficient High Performance Computing: Theoretical Foundation and Enabling Technology” with Rong Ge, Marquette University

Abstract:

Highly efficient scalable computing systems are crucial to scientific discovery and technology innovation. However, the scalability of HPC systems is increasingly constrained by the power requirement and the necessity to limit the power density of components and server rooms. Comprising millions of components, today’s HPC systems already consume megawatts of power; to meet an insatiate demand for performance from mission-critical applications, future systems will consist of even more components and consume more power. To resolve the conflicting needs of scaling performance and limiting power, we need to develop theoretical foundation and enabling technology for efficient and scalable computing on emerging and future computer systems. In this talk, I will introduce an experimental system approach to energy efficient high performance computing. With this approach, we first identify the performance and power inefficiency of applications on real HPC systems through prototyping, profiling and benchmarking. We then derive analytical models based on system abstraction and experimental data to describe the impact of hardware/software parameters on performance, power, and energy efficiency. Guided by experimental findings and model projections, we design algorithms, middleware, and system software to interact with hardware for better efficiency, scalability, and reliability. I will discuss several models and tools developed with this approach, including power-aware speedup, performance and energy aware cooperative hybrid computing, and cross-layer power-bounded HPC scheduling, and summarize relevant results and their implications on emerging HPC architecture, algorithm and system design.

Bio:

Dr. Rong Ge is an Assistant Professor and Director of High Performance Computing Laboratory in the Department of Mathematics, Statistics and Computer Science at Marquette University. She graduated Tsinghua University with a B.S. and M.S. in fluid mechanics, and received her Ph.D. degree in computer science from Virginia Tech. Her research interest includes parallel and distributed systems, energy-efficient computing, high performance computing, data intensive computing, and performance analysis and modeling. Dr. Ge is among the earlier researchers who have studied and promoted energy efficient HPC and developed theories, models, and system software to improve the energy efficiency for compute- and data-intensive computing. She is a recipient of the NSF CAREER Award in 2015. Dr. Ge has served on the technical program committee for multiple conferences including SC, IPDPS, ICPP, HPDC, and CCGrid, regularly reviewed manuscripts for TPDS, TC, TCC, JPDC, Parallel Computing, and IEEE Computer, and been actively involved with workgroups such as Green 500, Energy Efficient HPC Working Group, and SPEC Power.
