What is the Exascale Computing Project? • As part of the National Strategic Computing initiative, 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 petaflop machines. • ECP’s work encompasses – applications, – system software, – hardware technologies and architectures, and – workforce development to meet the scientific and national security mission needs of DOE. 2 Exascale Computing Project
Four key challenges that must be addressed to achieve exascale • Parallelism • Memory and Storage • Reliability • Energy Consumption 3 Exascale Computing Project
What is a capable exascale computing system? A capable exascale computing system requires an entire computational ecosystem that: This ecosystem • Delivers 50× the performance of today’s 20 PF will be developed using systems, supporting applications that deliver high- a co-design approach to deliver new software, fidelity solutions in less time and address problems applications, platforms, and of greater complexity computational science capabilities at heretofore unseen • Operates in a power envelope of 20–30 MW scale • Is sufficiently resilient (average fault rate: ≤1/week) • Includes a software stack that supports a broad spectrum of applications and workloads 4 Exascale Computing Project
