Editorial: Algorithmic requirements for HPC

Adaptivity is a key tool for HPC, the larger the problem becomes, the more important adaptive grid resolution becomes. This can be seen from the following example computed by Arne Nägel, Sebastian Reiter and Andreas Vogel. Take the skin permeation model from (Kreienbühl et al, this issue) and do a weak scaling of this problem with uniform refinement up to 65,536 cores (JuQueen) and compare with...

Algorithmic requirements for swarm intelligence in differently coupled collective systems

Swarm systems are based on intermediate connectivity between individuals and dynamic neighborhoods. In natural swarms self-organizing principles bring their agents to that favorable level of connectivity. They serve as interesting sources of inspiration for control algorithms in swarm robotics on the one hand, and in modular robotics on the other hand. In this paper we demonstrate and compare a...

Experiences and Requirements for Interoperability Between HTC and HPC-driven e-Science Infrastructure

Recently, more and more e-science projects require resources in more than one production e-science infrastructure, especially when using HTC and HPC concepts together in one scientific workflow. But the interoperability of these infrastructures is still not seamlessly provided today and we argue that this is due to the absence of a realistically implementable reference model in Grids. Therefore...
