Schematic overview of the software design with the separation of the front-end and back-end functionalities. PynPoint offers a simple front end which can be used to define a sequence of pipeline modules. Management of the data and the computational resources (i.e., multiprocessing and memory usage) is handled by the back-end of PynPoint. Reading, processing, and writing modules are attached to the pipeline and sequentially executed while results are stored in the central database. The architecture allows the user to easily rerun pipeline modules and evaluate the results at various stages of the data reduction.
