In the past decade, high-end computing (HEC) architectures have become an important tool in all aspects of scientific discovery. Having ushered in an era where HEC-enabled simulation is considered a third pillar of science along with theory and experiment, HEC architectures have quickly become a credible direction of focused and long-term research. Rapid advances are taking place in different aspects of HEC architectures in an effort to improve performance. Multi- and many-core systems (e.g., Intel, AMD), accelerators (e.g., GPGPUs), high-speed network architectures (e.g., InfiniBand), and integrated computing platforms (Blue Gene, Cray) have been introduced along this effort. Recently, reconfigurable architectures (e.g., FPGAs) have shown dramatic gains in performance and energy for some types of high-performance applications. The growing convergence of HEC and data-driven AI computing is also bringing efficient Application Specific Integrated Circuit (ASIC) architectures into the HEC world.

These advances in the fundamental architecture of HEC architectures mean little, however, without appropriate software components that enable high-performance applications to take advantage of these architectures. System software plays a crucial role in exposing the raw performance of the underlying hardware in an efficient manner. Equally important are productive, expressive, portable, and high-performance Parallel Programming models that enable scientists to express parallel algorithms so that they can execute efficiently on various HEC architectures.

The goal of this workshop is to bring together researchers and practitioners in parallel programming models and systems software for high-end computing architectures. Please join us in a discussion of new ideas, experiences, and the latest trends in these areas at the workshop.

Accepted papers will be published by the ACM International Conference Proceedings Series (ICPS), in conjunction with those of other ICPP workshops, in a volume entitled 50th International Conference on Parallel Processing Workshops (ICPP 2021 Workshops). This volume will be available for download via the ACM Digital Library.
