Hello, A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee. Applicant's name: Ivan Sadovskyy Applicant's institution: ANL Applicant's division: MSD Project Name: perc Project title: Optimizing superconductor transport properties through large-scale simulation Associated funding: SciDAC Other Systems: Cooley @ ALCF, 100000 node-hours Science: 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. So far the quest for optimal superconductors with respect to largest critical current was only conducted via the Edisonian process of laborious experimental trial and error. The overall project is carried out in collaboration with SciDAC Institutes using large-scale computation and leveraging DOE’s leadership-class computing facilities. Project description: -- Solution of the Ginzburg-Landau equations in unstructured mesh. Usage of link variables in finite-element method to simulate large external magnetic field C++/Python -- Analysis of the vortex dynamics in two-component media (typically superconducting and non-superconducting components) near percolation threshold Python We plan to test a scalability of the unstructured FE code with link variables, which requires ~30000 core-hours. The previous implementation of the code in structured grid shows a great performance on GPU-based clusters, see http://arxiv.org/abs/1409.8340 for details. We plan to make a statistical analysis of vortex dynamics in two-component media, which requires ~20000 core-hours Expected number of project members: 2-3 Industry partnership: AMSC, SuperPower Project URL: http://oscon-scidac.org/ Requested allocation: 50000 Q1: 0 Q2: 0 Q3: 0 Q4: 50000 Justification: Storage requirements: 1 TB should be more then enough The requester has used undetermined amount hours of their initial startup project.
