2018年10月9日，南加利福尼亚大学Viktor K. Prasanna教授来中心访问，并作了题为“Accelerating Data Science at the Edge Using FPGAs ”的学术报告。

Abstract: Data Science has matured over the past few years with novel applications in diverse areas including health, energy, autonomous x, etc. Many of these are cyber physical social systems with strict requirements of latency, throughput and energy efficiency. With recent dramatic advances in FPGAs, these devices are being used along with multi-core and emerging memory technologies to realize advanced platforms to accelerate variety of complex applications. This talk will review our work in the Data Science Lab at USC (dslab.usc.edu) and the promise of reconfigurable computing (fpga.usc.edu) leading up to current trends in accelerators for data science. We will illustrate FPGA-based parallel architectures and algorithms for a variety of data analytics kernels in streaming graph processing and machine learning for “edge” processing. While demonstrating algorithm-architecture co-design methodology to realize high performance accelerators for graphs and ML, we demonstrate the role of modeling and algorithmic optimizations to develop highly efficient IP cores. For graph embedding, we develop a novel computationally efficient technique using graph sampling and demonstrate scalable performance. For CNN inferencing, we develop parallel frequency domain convolution algorithms and data layouts to realize high throughput and energy efficient designs using FPGAs. We conclude by identifying opportunities and challenges in exploiting emerging heterogeneous architectures composed of multi-core processors, FPGAs, GPUs and coherent memory.
