Research topic: Scaling of an Arnoldi-Lanzos time propagation code for the description of molecular strong fi eld phenomena

Research abstract:
When looking at the effects induced by a laser on molecular
dynamics, a) structure, b) time propagation and c) post-analysis codes are required. The code which performs time propagation can often be the computational bottleneck. The current project aims to work on an existing Arnoldi-Lanzos time propagation code to ensure that it can scale for large to very large problems by using heterogeneous parallelisation techniques such as GPGPU, OpenMP and MPI.
