Journal ArticleDOI
Size scaling of turbulent transport in magnetically confined plasmas.
TL;DR: The local transport coefficient exhibits a gradual transition from a Bohm-like scaling for device sizes corresponding to present-day experiments to a gyro-Bohm scaling for future larger devices.
Book ChapterDOI
Compressing the incompressible with ISABELA: in-situ reduction of spatio-temporal data
Sriram Lakshminarasimhan,Neil Shah,Stephane Ethier,Scott Klasky,Robert Latham,Robert Ross,Nagiza F. Samatova +6 more
TL;DR: This work proposes an effective method for In-situ Sort-And-B-spline Error-bounded Lossy Abatement (ISABELA) of scientific data that is widely regarded as effectively incompressible and significantly outperforms existing lossy compression methods, such as Wavelet compression.
Journal ArticleDOI
ISABELA for effective in situ compression of scientific data
Sriram Lakshminarasimhan,Sriram Lakshminarasimhan,Neil Shah,Stephane Ethier,Seung-Hoe Ku,Choong-Seock Chang,Scott Klasky,Robert Latham,Robert Ross,Nagiza F. Samatova,Nagiza F. Samatova +10 more
TL;DR: The random nature of real‐valued scientific datasets renders lossless compression routines ineffective, and these techniques also impose significant overhead during decompression, making them unsuitable for data analysis and visualization, which require repeated data access.
Journal ArticleDOI
Gyrokinetic particle-in-cell simulations of plasma microturbulence on advanced computing platforms
TL;DR: The gyrokinetic toroidal code (GTC) as discussed by the authors was developed at the Princeton Plasma Physics Laboratory to study the effects of low-frequency microturbulence in fusion plasmas.
Journal ArticleDOI
Wave-particle decorrelation and transport of anisotropic turbulence in collisionless plasmas.
TL;DR: Comprehensive analysis of the largest first-principles simulations to date shows that stochastic wave-particle decorrelation is the dominant mechanism responsible for electron heat transport driven by electron temperature gradient turbulence with extended radial streamers.
