Parallel Programming Workshop

Abstract
The aim of these workshops is to give people who already have some programming experience an introduction into the numerics of linear solvers and the basics of parallel programming. The focus is on iterative solvers, the programming models MPI and OpenMP, domain decomposition, load balancing and parallel numerics. Language support is given for Fortran, C and C++.
Message Passing with MPI is the major programming model on large distributed-memory systems in high-performance computing. OpenMP is dedicated to shared memory systems.
Hands-on sessions will allow users to immediately test linear solver programming and to understand what the basic constructs of MPI and OpenMP are meant to do.
