UPC++ Tutorial at SC20
Paul Hargrove
I am pleased to announce that the Pagoda project will present a half-day UPC++ Tutorial at the virtual SC20 conference in November. The virtual format of SC this year means the tutorials are presented on an earlier, non-conflicting day (initial broadcast on Tues Nov 10th at 2:30pm EST) and are less than half as expensive to attend relative to previous years. The tutorial will include interactive hands-on exercises along with an introduction to the UPC++ library. Speakers notably include Professor Katherine Yelick, a highly distinguished lecturer and internationally recognized and decorated researcher.
Details for the tutorial are available at this SC20 page, and registration is here: SC20 Registration

This is a reminder that there will be a UPC++ tutorial at SC20, in two weeks from today.
Links are in the original email, and the abstract appears below.
We’re also pleased to announce the presentation will include a late-breaking case study from a COVID-19 lung simulation written in UPC++.

When:
Tues Nov 10th at 2:30pm EST - note, the week before technical program!
(Rebroadcast at 2:30pm Japan Standard Time)

Abstract:
UPC++ is a C++ library supporting Partitioned Global Address Space (PGAS) programming. The UPC++ API offers low-overhead one-sided Remote Memory Access (RMA) and Remote Procedure Calls (RPC), along with future/promise-based asynchrony to express dependencies between asynchronous computations and data movement. UPC++ supports simple, regular data structures as well as more elaborate distributed structures where communication is fine-grained, irregular, or both. UPC++'s support for aggressive asynchrony enables the application to overlap communication to reduce communication wait times, and the GASNet communication layer provides efficient low-overhead RMA/RPC on HPC networks.This tutorial introduces basic concepts and advanced optimization techniques of UPC++. We discuss the UPC++ memory and execution models and examine basic algorithm implementations. Participants gain hands-on experience incorporating UPC++ features into several application examples. We also examine three irregular applications (COVID-19 lung simulation, metagenomic assembler and multifrontal sparse solver) and describe how they leverage UPC++ features to optimize communication performance.
