Webcodes are lacking a modern software interface for coupling internally to other codes and no parallelized versions of these codes exist. This is not least due to the fact that these codes share a development history of up to 40 years. Without such an interface the only way to share data between two codes is writing and reading files. Due to the http://malb.io/discrete-subgroup/slides/2016-05-04-burr.pdf
