The Muon (g-2) Experiment, E989 at Fermilab, will measure the muon anomalous magnetic moment a factor-of-four more precisely than was done in E821 Brookhaven National Laboratory AGS. result appears to be greater Standard-Model prediction by three standard deviations. When combined with expected improvement hadronic contributions, should able determine definitively whether or not is evidence for physics beyond Standard Model. After review of motivation and basic technique, which use storage...

As electric vehicle adoption increases, charging stations will face greater demand and have energy needs. This paper outlines a system for reserving charging, using reservation called an packet. The proposed packets are composed of the duration energy. Using packet reservations from EV users as part inputs, this developed management through optimization algorithm to achieve reduced total costs each vehicle. A case study is presented demonstrate effectiveness method in reducing costs, peak...

Finding a software engineering approach that allows for portability, rapid development, open collaboration, and performance high computing on GPUs CPUs is challenge. We implement portability scheme using the Numba compiler Python in Monte Carlo / Dynamic Code (MC/DC), new neutron transport application methods development. Using this scheme, we have built MC/DC as single source, language, can run pure Python, compiled CPU, or GPU solver. In mode, use paired with an asynchronous scheduler...

We discuss the current development of MC/DC (Monte Carlo Dynamic Code). is primarily designed to serve as an exploratory Python-based MC transport code. However, it seeks offer improved performance, massive scalability, and backend portability by leveraging Python code-generation libraries implementing innovative abstraction strategy compilation scheme. Here, we verify capabilities perform initial performance assessment. found that can run hundreds times faster than its pure mode about 2.5...

To find deterministic solutions to the transient $S_N$ neutron transport equation, iterative schemes are typically used treat scattering (and fission) source terms. We explore one-cell inversion iteration scheme do this on GPU and make comparisons a scheme. examine convergence behavior, through analysis of spectral radii, both iterations. further boost parallel efficiency, we derive higher-order discretization method, simple corner balance (in space) multiple time), add more work threads...

Monte Carlo Application Toolkit (MCATK) commonly uses surface tracking on a structured mesh to compute scalar fluxes. In this mode, higher fidelity requires more cells and isotopes thus computational overhead -- since every time particle changes cells, new cross-sections must be found for all materials in given cell even if no collision occurs that cell. We implement hybrid version of Woodcock (delta) imposed alleviate the number cross-section lookups. This algorithm computes an...

Resolvable designs with two blocks per replicate are studied from an optimality perspective. Because in practice the number of replicates is typically less than treatments, arguments can be based on dual information matrix and consequently given terms block concurrences. Equalizing concurrences for sizes often, but not always, best strategy. Sufficient conditions established various strong optimalities a detailed study E-optimality offered, including characterization E-optimal class. Optimal...
