High-performance implementation of Chebyshev filter diagonalization for interior eigenvalue computations
Andreas Pieper, Moritz Kreutzer, Andreas Alvermann +5
We study Chebyshev filter diagonalization as a tool for the computation of many interior eigenvalues of very large sparse symmetric matrices. In this technique the subspace project…
GHOST: Building blocks for high performance sparse linear algebra on heterogeneous systems
Moritz Kreutzer, Jonas Thies, Melven Röhrig-Zöllner +7
While many of the architectural details of future exascale-class high performance computer systems are still a matter of intense research, there appears to be a general consensus t…
Building a fault tolerant application using the GASPI communication layer
Faisal Shahzad, Moritz Kreutzer, Thomas Zeiser +4
It is commonly agreed that highly parallel software on Exascale computers will suffer from many more runtime failures due to the decreasing trend in the mean time to failures (MTTF…
Electron confinement in graphene with gate-defined quantum dots
Holger Fehske, Georg Hager, Andreas Pieper
We theoretically analyse the possibility to electrostatically confine electrons in circular quantum dot arrays, impressed on contacted graphene nanoribbons by top gates. Utilising…
