Recorder: Comprehensive Parallel I/O Tracing and Analysis
Chen Wang, Izzet Yildirim, Hariharan Devarajan +2
This paper presents Recorder, a parallel I/O tracing tool designed to capture comprehensive I/O information on HPC applications. Recorder traces I/O calls across various I/O layers…
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…
Understanding the Communication Needs of Asynchronous Many-Task Systems -- A Case Study of HPX+LCI
Jiakun Yan, Hartmut Kaiser, Marc Snir
Asynchronous Many-Task (AMT) systems offer a potential solution for efficiently programming complicated scientific applications on extreme-scale heterogeneous architectures. Howeve…
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…
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…
