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…
Extreme Scale-out SuperMUC Phase 2 - lessons learned
Nicolay Hammer, Ferdinand Jamitzky, Helmut Satzger +36
In spring 2015, the Leibniz Supercomputing Centre (Leibniz-Rechenzentrum, LRZ), installed their new Peta-Scale System SuperMUC Phase2. Selected users were invited for a 28 day extr…
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…
Modeling and analyzing performance for highly optimized propagation steps of the lattice Boltzmann method on sparse lattices
M. Wittmann, T. Zeiser, G. Hager +1
Computational fluid dynamics (CFD) requires a vast amount of compute cycles on contemporary large-scale parallel computers. Hence, performance optimization is a pivotal activity in…
Asynchronous MPI for the Masses
Markus Wittmann, Georg Hager, Thomas Zeiser +1
We present a simple library which equips MPI implementations with truly asynchronous non-blocking point-to-point operations, and which is independent of the underlying communicatio…
Domain decomposition and locality optimization for large-scale lattice Boltzmann simulations
Markus Wittmann, Thomas Zeiser, Georg Hager +1
We present a simple, parallel and distributed algorithm for setting up and partitioning a sparse representation of a regular discretized simulation domain. This method is scalable…
