Overview
The task of a high performance computing system is to carry out its
calculations (mainly scientific applications) with maximum performance
and energy efficiency.

Up until now, this goal could only be achieved by exclusively
assigning an appropriate number of cores/nodes to parallel
applications. As a
consequence, applications had to be highly optimised in order to achieve
even only a fraction of a supercomputer's peak performance which
required huge efforts on the programmer side.

This problem is expected to become more serious on future Exa-Scale
systems with millions of compute cores. Many of today's highly scalable
applications will not be able to utilise an Exa-Scale system's extreme
parallelism due to node specific limitations like e.g. I/O bandwidth.
Therefore, to be able to efficiently use future supercomputers,
it will be necessary to simultaneously run more than one application
on a node.

To be able to efficiently perform co-scheduling, applications must
not slow down each other, i.e. candidates for co-scheduling could
e.g. be a memory-bound and a compute bound application.

Within this context, it might also be necessary to dynamically migrate
applications between nodes if e.g. a new application is scheduled
to the system.
In order to be able to monitor performance and energy
efficiency during operation, additional sensors are required. These
need to be correlated to running applications to deliver values for key
performance indicators.
