How to work at Jülich in a nutshell

Working at Jülich might seem an easy task for the inexperienced student. However, it is one of the most difficult challenges that one can face. It is impossible to keep track of how many students have tried, innocent as they

Making Quarks phli further

Simulations of Lattice Quantum Chromodynamics (the theory of quarks and gluons) are used to study properties of strongly interacting matter and can, e.g., be used to calculate properties of the quark-gluon plasma, a phase of matter that existed a few milliseconds after the Big Bang (at temperatures larger than a trillion degrees Celsius). Such simulations take up a large fraction of the available supercomputing resources worldwide.

A Fast Multipole Toolbox for GPU cluster

Modern multi- and many-core hardware architectures provide a huge amount of floating point operations (FLOPs). To harvest these FLOPs efficiently a lot of parallelism in the examined algorithm needs to be uncovered and exploited. Performance boosts are well hidden in low-level hardware features of the CPUs or GPUs. The great diversity and short life cycle of todays HPC hardware does not allow for hand-written, well-optimized assembly kernels anymore. This begs the question if we can utilize the hidden performance from high-level languages with greater abstraction possibilities like C++.
