Critically Missing Pieces in Heterogeneous Exascale Computing
SESSION: Critically Missing Pieces in Heterogeneous Exascale Computing
EVENT TYPE: Birds of a Feather
TIME: 5:30PM - 7:00PM
SESSION LEADER(S):Satoshi Matsuoka, Pavan Balaji
ABSTRACT: As we look forward to the exascale era, heterogeneous parallel machines are expected to play a massive role in architecting the largest systems in the world. While there is significant interest in these architectures, much of this interest is an artifact of the hype associated with them. For heterogeneous parallel machines to truly be a successful High Performance Computing platform, it is important that we look beyond this hype and learn what these architectures provide and what is critically missing in understanding the role these architectures would play in future systems. Some of these missing pieces include: (1) sound data and memory management techniques for accelerators, (2) resilience issues, (3) programming issues (languages, environments, compilers), (4) runtime support for multi-GPU and systems with clusters of accelerators, (5) tools (debugging, performance), (6) large-scale benchmarks and (7) auto-tuning techniques, amongst many others.
This birds-of-a-feather session would bring together researchers working on and interested in these aspects, that would require fundamental research from the community to address in the exascale time-frame. The organizers have invited several researchers working in these areas to describe their point-of-view and set the stage for an active discussion allowing the community to understand the complexity of these issues, and join together to address them. Invited presenters include: Wen-mei Hwu, Wu-chun Feng, Jeff Vetter, John Shalf and P. Sadayappan.
