Highlights

Comparison of Mantid’s “LoadEventNexus” wall-clock times for Mantid v5.0 release and our proposed strategy on Mantid’s latest implementation. Results are shown for “hot” cached files (accessed several times) showing universal improvements across different ORNL SNS/HFIR instrument generated raw NeXus files (CG2 is GP-SANS, CG3 is BIO-SANS, NOM is NOMAD).

Simulating a Neighborhood of Homes to Test the Performance of Load Management Software

An example of a code being run from the provided User Interface (UI). The program loads a model from a file (either on the user’s desktop or from the web server) in the top left, parses it to find the variables in mid-left, then the user launches the job and gets back the results in the bottom left. In the top right is a list of output files for viewing or downloading.

The UI for the Energy Storage System Test Bed. A list of completed use case simulations is displayed in a grid. A graph of the energy storage system's status over the course of running the use case is displayed, though all values are constant as the system does not yet have real hardware to run on. Other views allow for viewing the current queue of use cases and scheduling new use cases.
