Description

Large multidimensional neutron scattering datasets are routinely collected at neutron scattering facilities. Compared to other imaging tasks, the unique characteristics of neutron scattering data including binning along non-orthogonal axes and the need to distinguish between points with zero intensity and ones without detector coverage. Meeting user expectations to interactively visualize and manipulate multi-gigabyte datasets from at the beamline and their home institution at full resolution is a challenging task requiring special considerations. In this talk, I’ll discuss work we are undertaking to facilitate access to remote HPC resources capable of volume rendering with interactive frame rates. I’ll also talk about changes to data structures in the Mantid VSI that improve performance & reduce memory consumption. Examples of these improvements will be shown using data taken on various ORNL neutron scattering instruments. This research used resources at the High Flux Isotope Reactor and Spallation Neutron Source, a DOE Office of Science User Facility operated by the Oak Ridge National Laboratory.
