The Production-ready, Exascale-enabled Krylov Solvers for Exascale Computing (PEEKS) project will explore the redesign of solvers and extend the DOE’s Extreme-scale Algorithms and Solver Resilience (EASIR) project. Many large-scale scientific applications rely heavily on preconditioned iterative solvers for large linear systems. For these solvers to efficiently exploit extreme-scale hardware, both the solver algorithms and the implementations must be redesigned to address challenges like extreme concurrency, complex memory hierarchies, costly data movement, and heterogeneous node architectures.
The PEEKS effort aims to tackle these challenges and advance the capabilities of the ECP software stack by making the new scalable algorithms accessible within the Trilinos software ecosystem. Targeting exascale-enabled Krylov solvers, incomplete factorization routines, and parallel preconditioning techniques will ensure successful delivery of scalable Krylov solvers in robust, production-quality software that can be relied on by ECP applications.
