Benefits from using mixed precision computations in the ELPA-AEO and ESSEX-II eigensolver projects
Andreas Alvermann, Achim Basermann, Hans-Joachim Bungartz +30
We first briefly report on the status and recent achievements of the ELPA-AEO (Eigenvalue Solvers for Petaflop Applications - Algorithmic Extensions and Optimizations) and ESSEX II…
Chebyshev Filter Diagonalization on Modern Manycore Processors and GPGPUs
Moritz Kreutzer, Georg Hager, Dominik Ernst +3
Chebyshev filter diagonalization is well established in quantum chemistry and quantum physics to compute bulks of eigenvalues of large sparse matrices. Choosing a block vector impl…
CRAFT: A library for easier application-level Checkpoint/Restart and Automatic Fault Tolerance
Faisal Shahzad, Jonas Thies, Moritz Kreutzer +3
In order to efficiently use the future generations of supercomputers, fault tolerance and power consumption are two of the prime challenges anticipated by the High Performance Comp…
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…
