Call for Papers:

Directive-based programming models offer scientific applications a path on to HPCplatforms without undue loss of portability or programmer productivity. Using directives, application developers can port their codes to the accelerators incrementally while minimizing code changes. Challenges remain because the directives models need to support a rapidly evolving array of hardware with diverse memory subsystems, which may or may not be unified. The programming model will need to adapt to such developments, make improvements to raise its performance portability that will make accelerators as first-class citizens for HPC. Such improvements are being continuously discussed within the standard committees such as OpenMP and OpenACC. This workshop aims to capture the assessment of the improved feature set, their implementations and experiences with their deployment in HPC applications. The workshop aims at bringing together the user and tools community to share their knowledge and experiences of using directives to program accelerators.

Keynote Speaker:

Barbara Chapman, a Professor in the Department of Computer Science and Director of the Center for Advanced Computing and Data Systems (CACDS), University of Houston, Houston, TX, USA has been engaged in research on parallel programming languages and compiler technology for more than 15 years. Her research group has developed OpenUH, a state-of-the art open source compiler that is used to explore language, compiler and runtime techniques, with a special focus on multithreaded programming. Dr. Chapman has been involved with the evolution of the OpenMP directive-based programming standard since 2001. She also is a participant in the OpenSHMEM and OpenACC programming standards efforts. Her on-going research continues to advance these efforts. It also explores new approaches to optimize partitioned global address space programs, strategies for runtime code optimizations, compiler-tools interactions and high-level programming models for embedded systems.

Prof. Chapman completed her Ph.D. on software support for distributed memory programming at Queen’s University of Belfast, Northern Ireland, U.K.

Panel Session:

A panel session will be dedicated to discussion of current open problems, applications' requirements, drawbacks and future evolutions of high-level directive approaches for current and emerging architectures. A roadmap for accelerator directives will also be discussed.
