From Domain-Specific Accelerators to Spatial Architecture Exploration
Title: From Domain-Specific Accelerators to Spatial Architecture Exploration
Speaker: Dr. Jongeun Lee
Date and Time: Thursday, July 30, 10:30am
Location: ISEB 1310
Abstract:
Emerging scientific and machine learning workloads increasingly benefit from domain-specific hardware accelerators, yet designing efficient architectures for these applications requires both effective implementations and scalable methods for architectural exploration. In this talk, I will present our recent research on accelerator design and architecture exploration for spatial computing systems.
I will first introduce AccelOrb, an FPGA accelerator for Orb v2, a graph neural network-based machine learning force field (MLFF) used in molecular dynamics simulations. By analyzing the application’s computational bottlenecks and memory requirements, we develop a memoryaware streaming architecture that substantially improves performance while operating within the resource constraints of a modern FPGA.
Building on the lessons learned from accelerator implementation, I will then discuss FlowSpec, a flexible framework for modeling and simulating coarse-grained spatial architectures. Rather than targeting a single accelerator design, FlowSpec provides a scalable interface between application mapping and architectural simulation, enabling rapid exploration of diverse compute organizations and communication networks.
Together, these efforts highlight a research direction that bridges application-driven accelerator design with the systematic exploration of future spatial architectures.
