主讲人简介：

Cho-Li Wang is currently a Professor in the Department of Computer Science at The University of Hong Kong. Prof. Wang’s research is broadly in the areas of parallel architecture, operating systems, and software systems for Cloud and Big Data computing. He is/was on the editorial boards of scholarly journals, including IEEE Transactions on Cloud Computing (2013-) and IEEE Transactions on Computers (2006-2010). He has served as the programme chair for numerous conferences such as IEEE Cluster’03, CCGrid'09, ICPADS’09, Cluster’12, and IC2E’16; and the General Chair for IPDPS’12. He is the primary investigator of China's 863 project "Hong Kong Grid Point'' (2006-2011). He is also a member of China’s Supercomputing and Innovation Alliance.

内容提要：

The rise of graphics processing units (GPUs) in the data centers, in self-driving vehicles, and in mobile AR navigation systems is one of the latest technology trends. Compared with the CPU architecture, GPUs bring orders of magnitude more computing power with a significantly smaller hardware and energy footprint. Although current techniques (e.g., CUDA and OpenCL) can automatically parallelize and offload sizable workload onto the GPU, there are still a family of computation patterns that cannot be parallelized or executed efficiently on GPUs. In this talk, we will first discuss the emerging trends in GPU hardware architectures (e.g., the new AI chips), then introduce a new compiler and runtime platform, called Japonica, which helps in unfettering the power of the GPU with minimal programming effort.  We will show how Japonica accelerated OpenCL code execution on Nvidia/AMD GPUs, and Snapdragon mobile phone.  Our solutions could bring big opportunities to harness the power of GPUs for real-time analytics, deep learning, and artificial intelligence.
