Global gyrokinetic simulations of ASDEX Upgrade up to the transport time-scale with GENE-Tango
A. Di Siena, A. Banon Navarro, T. Luda +12
An accurate description of turbulence up to the transport time scale is essential for predicting core plasma profiles and enabling reliable calculations for designing advanced scen…
Stability Analysis of Inline ZFP Compression for Floating-Point Data in Iterative Methods
Alyson Fox, James Diffenderfer, Jeffrey Hittinger +2
Currently, the dominating constraint in many high performance computing applications is data capacity and bandwidth, in both inter-node communications and even more-so in on-node d…
Error Analysis of ZFP Compression for Floating-Point Data
James Diffenderfer, Alyson Fox, Jeffrey Hittinger +2
Compression of floating-point data will play an important role in high-performance computing as data bandwidth and storage become dominant costs. Lossy compression of floating-poin…
Bringing global gyrokinetic turbulence simulations to the transport timescale using a multiscale approach
Jeffrey B. Parker, Lynda L. LoDestro, Daniel Told +5
The vast separation dividing the characteristic times of energy confinement and turbulence in the core of toroidal plasmas makes first-principles prediction on long timescales extr…
High-order Discretization of a Gyrokinetic Vlasov Model in Edge Plasma Geometry
Milo R. Dorr, Phillip Colella, Mikhail A. Dorf +3
We present a high-order spatial discretization of a continuum gyrokinetic Vlasov model in axisymmetric tokamak edge plasma geometries. Such models describe the phase space advectio…
Kinetic Simulation of Collisional Magnetized Plasmas with Semi-Implicit Time Integration
Debojyoti Ghosh, Mikhail A. Dorf, Milo R. Dorr +1
Plasmas with varying collisionalities occur in many applications, such as tokamak edge regions, where the flows are characterized by significant variations in density and temperatu…
