A MECHANISM OF ADAPTIVELY SELECTING A SOLVER IN PMLP/PARSOL LIBRARY

V. A. Erzunov, A. A. Gorbunov
VANT. Ser.: Mat. Mod. Fiz. Proc 2009. Вып.1. С. 55-62.

The paper describes a mechanism of adaptively selecting a solver from PMLP/Parsol library and presents results of numerical experiments on parallel computations using MEDUZA technique intended for computational physics problems on irregular grids. The described mechanism allows automatically selecting an optimum solver for any phase of computations.
The adaptive mechanism of selecting solvers allows a significant gain in the program runtime.

Keywords: solver library, preconditioner, MEDUZA technique, solution of heat transfer equations.
