Are you interested in solving large linear or nonlinear systems using advanced iterative techniques on parallel computing clusters? If yes, PETSc toolkit can help.
PETSc has a wide range of solvers, including conjugate gradient, GMRES, Newton Krylov methods, and others implemented for parallel computing. In this hands-on workshop, you will learn by writing a PETSc code to solve a linear system resulting from a Poisson equation.
