Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Misun Min Project Name: Electromagnetics Division: MCS Project title: Computational Electromagnetics Associated funding: DOE AMR program and LDRD strategic Other Systems: BG/P (Intrepid) Science: This project is to develop NekCEM as an efficient computational tool equipped with advanced scalable numerical algorithms for understanding the fundamental optical properties and predicting optimal designs of next-generation electromagnetic devices, many of which have not been solved due to the limitations of current computational resources and the unavailability of a high-fidelity, high-efficiency code to run on these advanced resources. This project will enable scientists in the relevant computational electromagnetic communities to advance new scientific discoveries through highly efficient and accurate modeling with significant reduction of both the cost and the risk involved in conventional trial-and-error procedures. Project description: This project focuses on developing a massively parallel, open-source, high-fidelity electromagnetic code NekCEM. Numerical schemes are based on high-order approximations in space and time. Spectral-element discretizations are used based on hexahedral element meshes. Recent progress with communication kernel update in NekCEM demonstrate strong scaling with 60% efficiency on 131K cores at Argonne BG/P, even with small number of grid points per core (224 points per core), compared to a base case of 16K cores with 68,250 points per core. Using NekCEM, we will undertake simulation-based investigations for the following two application problems. (1) For the future International Linear Collider (ILC) linac cryomodule for generating high-quality light beams, extensive simulations will be performed to predict beam loss for ultra-short bunch beams, typically less than 0.03 mm in length, and many-meter beam propagations. These billion dollar collider systems are to be built in the 2018-2020 timeframe. Better design in the 2015 timeframe will lead to more effective colliders at lower cost. (2) For subwavelength nanosensors to detect unique signatures of chemical and biological structures of molecules, simulations will focus on optimizing the geometric parameters of metallic, thin-film, nanohole systems for single-molecule detections using surface-enhanced Raman scattering techniques. These will lead to fast and inexpensive detectors for medical tests. Our development will include a new implementation of applications in nano solar cell simulations. Currently, NekCEM project has four main developers (Misun Min, Jin Xu, Mike Fairchild,Jing Fu, Taehun Lee, Kalu Uga).
