Deploying Containerized QuantEx Quantum Simulation Software on HPC Systems
David Brayford, John Brennan, Momme Allalen +4
The simulation of quantum circuits using the tensor network method is very computationally demanding and requires significant High Performance Computing (HPC) resources to find an…
Optimizing the hybrid parallelization of BHAC
Salvatore Cielo, Oliver Porth, Luigi Iapichino +3
We present our experience with the modernization on the GR-MHD code BHAC, aimed at improving its novel hybrid (MPI+OpenMP) parallelization scheme. In doing so, we showcase the use…
Honing and proofing Astrophysical codes on the road to Exascale. Experiences from code modernization on many-core systems
Salvatore Cielo, Luigi Iapichino, Fabio Baruffa +2
The complexity of modern and upcoming computing architectures poses severe challenges for code developers and application specialists, and forces them to expose the highest possibl…
ECHO-3DHPC: Advance the performance of astrophysics simulations with code modernization
Matteo Bugli, Luigi Iapichino, Fabio Baruffa
We present recent developments in the parallelization scheme of ECHO-3DHPC, an efficient astrophysical code used in the modelling of relativistic plasmas. With the help of the Inte…
Performance Optimisation of Smoothed Particle Hydrodynamics Algorithms for Multi/Many-Core Architectures
Fabio Baruffa, Luigi Iapichino, Nicolay J. Hammer +1
We describe a strategy for code modernisation of Gadget, a widely used community code for computational astrophysics. The focus of this work is on node-level performance optimisati…
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…
