A New Lens on Multi-GPU Communication: API-Level Memory Models for Portable Optimization
Johnathan Alsop, Bradford Beckmann, Brandon Potter +5
As network communication increasingly becomes a performance bottleneck for ML and HPC workloads, it is more important than ever to optimize multi-GPU data transfers. Recently, low-…
Multithreaded Fine-Grained Asynchronous BSP for Integer Sorting with LCI and OpenMP
Minyu Cheng, Jiakun Yan, Marc Snir
The bulk synchronous parallel (BSP) model struggles with irregular workloads due to rigid global communication. While fine-grained asynchronous BSP (FA-BSP) improves overlap, exist…
Examining MPI and its Extensions for Asynchronous Multithreaded Communication
Jiakun Yan, Marc Snir, Yanfei Guo
The increasing complexity of HPC architectures and the growing adoption of irregular scientific algorithms demand efficient support for asynchronous, multithreaded communication. T…
LCI: a Lightweight Communication Interface for Efficient Asynchronous Multithreaded Communication
Jiakun Yan, Marc Snir
The evolution of architectures, programming models, and algorithms is driving communication towards greater asynchrony and concurrency, usually in multithreaded environments. We pr…
Contemplating a Lightweight Communication Interface for Asynchronous Many-Task Systems
Jiakun Yan, Marc Snir
Asynchronous Many-Task Systems (AMTs) exhibit different communication patterns from traditional High-Performance Computing (HPC) applications, characterized by asynchrony, concurre…
Understanding the Communication Needs of Asynchronous Many-Task Systems -- A Case Study of HPX+LCI
