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…
Characterizing Synchronization in Time Series using Information Measures Extracted from Symbolic Representations
Roberto Monetti, Wolfram Bunk, Ferdinand Jamitzky
We present a methodology to characterize synchronization in time series based on symbolic representations. A symbol is linked to a sequence of numbers through the rank-order of its…
Detecting non-linearities in data sets. Characterization of Fourier phase maps using the Weighted Scaling Indices
Roberto A. Monetti, Wolfram Bunk, Ferdinand Jamitzky +2
We present a methodology for detecting non-linearities in data sets based on the characterization of the structural features of the Fourier phase maps. A Fourier phase map is a 2D…
Reconnection rate for the steady-state Petschek model
Nikolai V. Erkaev, Vladimir S. Semenov, Ferdinand Jamitzky
Reconnection rate is found for the canonical simplest case of steady-state two-dimensional symmetric reconnection in an incompressible plasma by matching of outer Petschek solution…
A differential geometric approach to singular perturbations
F. Jamitzky
A differential geometric approach to singular perturbation theory is presented. It is shown that singular perturbation problems such as multiple-scale and boundary layer problems c…
