Reliable Decentralized Solvers in Unreliable Computing Environments
Alyson Fox | 22-ERD-045
Executive Summary
We will develop resilient, asynchronous, decentralized algorithms for linear system and eigenvalue problems by generalizing previously-inapplicable resilience-enhancement techniques to enrich conjugate gradient-based numerical solvers. By enabling decentralized systems to continue functioning despite hardware malfunctions and cyber intrusions, we can enhance our nation's ability to create scalable algorithms for exascale computing, as well as reliable infrastructure and communication systems.
