COVID-19 Update: SC21 Planning for an In-person Event

SC21 is planning for an In-person Event. Our workshop has been rescheduled to Sunday, November 14 from 10am – 6:30pm CDT. The event details of our workshop is still under discussion, especially whether in-person or virtual format. For more details on the SC21 event please also consult the Coronavirus & SC21.

About the Workshop

Architectures are evolving rapidly as we speak. In today’s systems, a single compute node is often equipped with multiple accelerators. Exploiting the maximum available parallelism out of such systems necessitates refactoring applications and using a programming approach that can make effective use of accelerators. Historically, the favored portable approaches, and the sole focus of our earlier workshops, were OpenMP offloading and OpenACC. Today, we understand there are other options and have extended the workshop to include the use of standard Fortran/C++, Sycl, DPC++, HIP, Kokkos, and Raja among several others that can provide scalable as well as portable solutions without compromising on performance.

This workshop will highlight the improvements over the state-of-art through accepted papers and prompt discussion through keynotes and panels. The workshop aims to showcase all aspects of accelerator programming for heterogeneous systems such as innovative high-level language or library approaches, lessons learned while using directives or other portable approaches to migrate scientific legacy code to modern systems, and compilation and runtime scheduling techniques.

In the past seven years of this workshop, WACCPD has been one of the major forums at SC to bring together programming model users, developers, and the tools community to share knowledge and experiences to tackle emerging complex parallel computing systems.
