A comparative evaluation of three volume rendering libraries for the visualization of sheared thermal convection
Jean M. Favre, Alexander Blass
Oceans play a big role in the nature of our planet, about of our earth is covered by water. Strong currents are transporting warm water around the world making life possi…
From Piz Daint to the Stars: Simulation of Stellar Mergers using High-Level Abstractions
Gregor Daiß, Parsa Amini, John Biddiscombe +7
We study the simulation of stellar mergers, which requires complex simulations with high computational demands. We have developed Octo-Tiger, a finite volume grid-based hydrodynami…
Red-blue pebbling revisited: near optimal parallel matrix-matrix multiplication
Grzegorz Kwasniewski, Marko Kabić, Maciej Besta +3
We propose COSMA: a parallel matrix-matrix multiplication algorithm that is near communication-optimal for all combinations of matrix dimensions, processor counts, and memory sizes…
Gyrokinetic Simulations on Many- and Multi-core Architectures with the Global Electromagnetic Particle-In-Cell Code ORB5
Noé Ohana, Claudio Gheller, Emmanuel Lanti +3
Gyrokinetic codes in plasma physics need outstanding computational resources to solve increasingly complex problems, requiring the effective exploitation of cutting-edge HPC archit…
ORB5: a global electromagnetic gyrokinetic code using the PIC approach in toroidal geometry
E. Lanti, N. Ohana, N. Tronko +20
This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code…
DCA++: A software framework to solve correlated electron problems with modern quantum cluster methods
Urs R. Hähner, Gonzalo Alvarez, Thomas A. Maier +4
We present the first open release of the DCA++ project, a high-performance research software framework to solve quantum many-body problems with cutting edge quantum cluster algorit…
