Present and future synoptic all-sky surveys are set to increase the number of known gravitationally lensed quasars from ∼100 to a few thousands, in the next decade. This will improve our understanding of quasar accretion discs and supermassive black holes through the effect of gravitational microlensing. GERLUMPH aims at improving our theoretical understanding and tools of microlensing, by producing thousands of high quality microlensing magnification maps. GERLUMPH is using the GPU-Supercomputer for Theoretical Astrophysics Research (gSTAR) to generate Terabytes of map data.
