Speaker: Yun (Eric) Liang, Peking University, China
Talk Title: Enabling Effective Performance Optimization Techniques for Heterogeneous System
Abstract: Heterogeneous systems that couple CPUs with accelerators such as Graphics Processing Units (GPUs) and Field Programmable Gate Arrays (FPGAs) have become ubiquitous in the computing world due to their tremendous computing power. However, performance tuning for GPUs and FPGAs is not trivial. In this talk, I will first present the performance modeling and optimization for FPGAs. I will introduce an accurate performance model for OpenCL workloads on FPGAs and how we accelerate deep learning applications on FPGAs. For the second half of the talk, I will present on-chip storage and machine learning optimization techniques for GPUs. The proposed techniques leverage on compile-time and run-time techniques to improve the cache performance, register utilization, pipeline utilization and overall performance.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Victor Preciado, University of Pennsylvania
Talk Title: From Local Network Structure to Global Graph Spectrum
Series: Fall 2017 Joint CSC@USC/CommNetS-MHI Seminar Series
Abstract: Using methods from algebraic graph theory and convex optimization we study the relationship between local structural features of a network and global spectral properties. In particular, we derive expressions for the so-called spectral moments of a graph in terms of local structural measurements, such as subgraph densities. Furthermore, we propose a series of semidefinite programs to compute bounds on the spectral radius, and other spectral properties, from a truncated sequence of spectral moments. Using our tools, we illustrate how important spectral properties of real-world networks are strongly constrained by local structural features.
Biography: Victor M. Preciado received his Ph.D. degree in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 2008. He is currently the Raj and Neera Singh Assistant Professor of Electrical and Systems Engineering at the University of Pennsylvania. He is a member of the Networked & Social Systems Engineering (NETS) program, the Warren Center for Network & Data Sciences, and the Applied Math and Computational Science (AMCS) program. He is a recipient of the 2017 National Science Foundation Faculty Early Career Development (CAREER) Award. His main research interests lie at the intersection of Big Data and Network Science; in particular, in using innovative mathematical and computational approaches to capture the essence of complex, high-dimensional dynamical systems. Relevant applications of this line of research can be found in the context of socio-technical networks, brain dynamical networks, healthcare operations, biological systems, and critical technological infrastructure.
