Overview of the DANSE architecture

Paul Kienzle, Przemek Klosowski

The DANSE project is a cooperative effort to build next generation neutron scattering software. The goal is to provide an extensible framework to integrate new and existing analysis software. To achieve this we are designing a dataflow architecture with computational components that can be distributed across different nodes of a network. End users and instrument scientists will be able to define new components and combine existing components in new ways as their data analysis needs change. The component cores can be implemented in almost any language, but a small Python wrapper must be provided for communication with the framework. DANSE subprojects are designing components for use in SANS, reflectometry, diffractometry, inelastic scattering, and engineering diffraction, and providing a user interface suitable for researchers who are not experts in the field of neutron scattering. We will describe the DANSE framework in detail with examples from reflectometry.
