Description
A new generation of instruments has resulted in increased complexity at all levels of the data chain. Furthermore, the experiments on these instruments, and the desire to compare the results to more detailed models, leads to a very large and diverse computational environment. Yet our goal is to facilitate the use of such facilities to expedite the users’ knowledge production. This contribution will provide several examples, from neutron beam lines at Oak Ridge National Laboratory, of how specialized computing functionality is being applied in various areas of data processing. Aspects that are working well and those where there are challenges will be discussed. Some of the topics to be presented will be integrating ever complex “laboratory on a beamline” concepts, utilizing computing platforms from the user’s tablet or PC to national scale supercomputing facilities, and working with specialized analysis codes. These analysis codes will include ab initio methods among others. Several necessary tradeoffs will be discussed. Specifically, web based vs. local machine interfaces and nimble, configurable vs. rigid, established workflows.
