Abstract

Big data analytics can claim a large share of credit for tackling many grand challenges of our time, such as understanding the spread of pandemics, designing extremely large-scale integrated circuits, and discovering life-saving medicines, among many others.  In the High-Performance Data Analytics (HPDA) lab at Stevens, we develop High-Performance algorithms and systems to analyze big real-world data, understand the contextual and casual relationships within entities and events, and deliver actionable knowledge to stakeholders in an acceptable time envelope.  In this talk, I will share our experiences designing and developing high-performance systems for random walk and graph sampling on large dynamic graphs (featured at SC '20 and Eurosys '23).  Subsequently, I will present three ongoing and future projects: (i) training and online inference of temporal Graph Neural Networks (GNNs) at scale; (ii) using machine learning to accelerate microarchitecture simulations (featured at Sigmetrics '22 and SC '22) and (iii) offloading the Department of Energy (DoE) flagship direct solvers (i.e., SuperLU) on the FPGA clusters (featured at TPDS).
