Funding Information:
Simulations and code development discussed in this article were performed on the Blue Waters machine at NCSA under support from NSF PRAC awards 1440025, 1515792, and 1713200, as well as a subcontract from the Blue Waters project at NCSA. Partial support for the code development also came from contracts from the Los Alamos and Sandia National Laboratories. The scientific research described here was supported by the NSF through CDS&E grant AST-1413548 and through subcontracts from NSF’s JINA-CEE center (PHY-1430152). Simulations were also carried out on Canada’s Westgrid resources and research supported by an NSERC Discovery grant. Srend development was partly supported by NASA under award number NNX15AQ02A.
