High Performance Computing Seminar Series:The Exascale Computing Project: Accelerating Science-Driven HPC
The U.S. is increasingly dependent on high performance computing (HPC) to address key challenges in scientific discovery, energy assurance, economic competitiveness, and national security. As part of the National Strategic Computing initiative, the Department of Energy Exascale Computing Project (ECP) was established to accelerate delivery of a capable exascale computing system that integrates hardware and software capability to deliver approximately 50 times more performance than today's 20-petaflops machines on mission critical applications. Scientific applications ready and able to address challenge problems of U.S. interest are the driving force behind the ECP, hence the ECP is responsible for ensuring exascale application readiness and delivering scalable science and engineering performance. In this talk, I will summarize the objectives and current status of the ECP and discuss some of the key challenges facing HPC applications as they prepare for exascale systems, including performance portability, software co-design and the need for a well-supported software ecosystem with common interfaces.
