Scientific Simulations on Thousands of GPUs with Performance Portability
Abstract:
"Developing your application for GPUs destroys portability to other platforms." We'll debunk this and other myths as we describe how we have solved the performance-portability challenge, allowing two separate scientific applications (which simulate complex fluids and fundamental particle physics, respectively) to effectively utilize machines such as the world's largest GPU-accelerated supercomputer, Titan at Oak Ridge, while remaining completely portable to multi-core or many-core CPU-based systems when GPUs are unavailable. The key ingredient is a new simplistic abstraction layer called targetDP, which targets data parallel hardware in a platform-agnostic but performance-portable manner.
