Anderson Acceleration in the KINSOL Nonlinear Solver Package
July 26, 2023
Carol S. Woodward and David J. Gardner Anderson acceleration (AA) has emerged as an alternative to Newton’s method for solving systems of nonlinear, algebraic equations. This talk will discuss the implementation of Anderson acceleration within the KINSOL nonlinear solver package contained in SUNDIALS. As part of SUNDIALS, this implementation is equipped with optoinal support on several high performance computing platforms, including distributed memory, threaded, GPU-based, and hybrid distributed memory-GPU systems. An overview of the implementation, how to use it, and examples of its use will be included.
