Description
In this demonstration, we will go through the distributed simulation of a general linear PDE by exploiting the tools made available by the PSBLAS/AMG4PSBLAS environment. We will start by discussing the issue of data distribution among the processors and the ones relative to the construction of the associated linear system. Then, we will show how to set-up and build the preconditioner in the AMG4PSBLAS library for solving such a system. After these two stepping stones have been achieved, we will briefly discuss the portability of the solution step to a hybrid parallel setting involving the usage of GPU and how the library is interfaced to face also non-linear problems by means of Newton-type algorithms.
