Nonlocal effects in negative triangularity TCV plasmas
G. Merlo, Z. Huang, C. Marini +7
Global gradient driven GENE gyrokinetic simulations are used to investigate TCV plasmas with negative triangularity. Considering a limited L-mode plasma, corresponding to an experi…
Nonlinear symmetry breaking in electron temperature gradient driven turbulence
Salomon Janhunen, Gabriele Merlo, Frank Jenko +3
Nonlinear symmetry breaking may occur in systems with two or more states whose linear dynamics displays certain symmetries, one of which is preferred nonlinearly. We have identifie…
FanStore: Enabling Efficient and Scalable I/O for Distributed Deep Learning
Zhao Zhang, Lei Huang, Uri Manor +5
Emerging Deep Learning (DL) applications introduce heavy I/O workloads on computer clusters. The inherent long lasting, repeated, and random file access pattern can easily saturate…
Gyrokinetic GENE simulations of DIII-D near-edge L-mode plasmas
T. F. Neiser, F. Jenko, T. A. Carter +7
We present gyrokinetic simulations with the GENE code addressing the near-edge region of an L-mode plasma in the DIII-D tokamak. At radial position , simulations with the i…
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…
Cross-code gyrokinetic verification and benchmark on the linear collisionless dynamics of the geodesic acoustic mode
A. Biancalani, A. Bottino, C. Ehrlacher +10
The linear properties of the geodesic acoustic modes (GAM) in tokamaks are investigated by means of the comparison of analytical theory and gyrokinetic numerical simulations. The d…
