Parallelization Of The GMRES Method

Sammanfattning: In this thesis a GMRES method is constructed and tested. The method is implemented in a C++ program with the MPI protocol to make it parallel. The parallel parts of this program are discussed in detail, especially the communication and the partitioning of the data between the processes. In the tests that were conducted we come to three important conclusions: the method works as expected, a substantial improvement is observed when more processes are introduced, and the method seems to be stable for very large systems.
