The Lightweight Communication Interface (LCI) is an experimental communication library aiming for better asynchronous multithreaded communication support, both in terms of performance and programmability. It is also a research tool helping us understand how to design communication libraries to better fit the needs of dynamic programming systems/applications. It features a simple, incrementally refinable interface unifying all common point-to-point communication primitives and an atomic-based runtime for maximum threading efficiency. It has been integrated into established asynchronous many-task systems such as HPX and shown significant performance improvement on microbenchmarks/real-world applications. This talk will present an overview of its interface and software design and showcase its performance.
Bio: Jiakun Yan is a fifth-year Ph.D. student at UIUC, advised by Prof. Marc Snir. His research involves exploring better communication library designs for highly dynamic/irregular programming systems and applications. He is the main contributor to the Lightweight Communication Interface (LCI) Project and the HPX LCI parcelport.
