Most applications running on supercomputers achieve only a fraction of a system's peak
performance. It has been demonstrated that the co-scheduling of applications can improve …

The continuous growth of supercomputers is accompanied by increased complexity of the
intra‐node level and the interconnection topology. Consequently, the whole software stack …

Virtualization has become an indispensable tool in data centers and cloud environments to
flexibly assign virtual machines (VMs) to resources. Virtualization also becomes more and …

It is predicted that the number of cores per node will rapidly increase with the upcoming era
of exascale supercomputers. As a result, multiple applications will have to share one node …

Abstract Only few High-Performance Computing (HPC) applications exploit the whole
