[Seminar] Specializing the Computing System for Graph Algorithms

Tuesday, December 6, 2022

11:00 am - 12:00 pm


Xuhao Chen, Ph.D.
Research Scientist

PGH 232


Numerous applications in social networks, e-commerce, biomedicine and security, are driven by graph algorithms. The graph data is massive and sparse, which poses great challenges in computing system design. In thistalk, I will describe experiences creating abstractions, system design principles, optimization techniques and automation methodologies for graph computing, across different layers of the system stack, including both software and hardware. As I will demonstrate, despite the complex computational and data access behaviors in graph algorithms, cross-layer system specialization can effectively unlock the potential of graph computing.
