One of the hard realities is that the hardware continues to evolve very rapidly with diverse memory subsystems or cores with different ISAs or accelerators of varied types. The HPC community is in constant need for sophisticated software tools and techniques to port legacy code to these emerging platforms. Maintaining a single code base yet achieving performance portable solution continues to pose a daunting task. Directive-based programming models such as OpenACC, OpenMP tackle this issue by offering scientists a high-level approach to accelerate scientific applications and develop performance portable solutions. This enables accelerators to be first-class citizens for HPC!

To address the rapid pace of hardware evolution, developers continue to explore and add richer features to the various (parallel) programming standards. Domain scientists continue to explore the programming and tools space while preparing themselves for future Exascale systems.

This workshop aims to solicit papers that explore innovative language features – their implementations, compilation & runtime scheduling techniques, performance optimization strategies, autotuning tools exploring the optimization space and so on.

WACCPD has been one of the major forums for bringing together the users, developers and tools community to share their knowledge and experiences of using directives and similar approaches to program emerging complex systems.
