The SciDAC partnership Optimizing superconductor transport properties through large-scale simulation (OSCon) was established in September 2012. The main objective of this project is to develop and apply novel methods for optimizing superconductors for energy applications using large-scale computational algorithms and tools. The resulting numerical tools will pave the way for a systematic method to design superconductors with high critical currents. he overall project is carried out in collaboration with SciDAC Institutes using large-scale computation and leveraging DOE’s leadership-class computing facilities.
