MoSGrid (Molecular Simulation Grid) is a user-friendly and highly efficient science gateway which contains three domains for the different methodologies used in chemistry: quantum chemistry, molecular dynamics, and docking. Workflows are implemented by using the WS-PGRADE technology. By adding an abstraction layer, we are able to develop meta-metaworkflows for quantum chemical applications and a combination between quantum chemical and molecular dynamics applications. This approach allows researchers to easily and more quickly create highly complex workflows allowing them to shorten the time-to-result considerably.
