This workshop brings together leading researchers and software designers at the forefront of the application of high-level directives to program accelerator-based architectures. Using directives improve productivity, and program portability with minimal changes to the applications while achieving good power-efficiency and performance. HPC researchers and programmers (including Energy, Climate, Oil & Gas, Computational Chemistry, and Machine Learning) wishing to tap into the performance benefits of commodity accelerators are starting to use directives to program accelerators including OpenACC, OpenMP and other similar programming interfaces vigorously to tap into commodity accelerators and speed up applications. The goal of this workshop is to bring together users, vendors, and tools providers to share their knowledge and experiences to program heterogeneous systems using directive-based programming interfaces such as OpenACC, OpenMP, etc to achieve good performance. This year's workshop will also emphasize in the future direction of accelerator programming using directives and how we can address better the user and tools-ecosystem needs. Although, this is a workshop for accelerator programming using directives, we welcome ideas used for other languages/APIs that may be used to interoperate with directives, used to translate the directives, or target the directives.
