DEADLINE EXTENDED: November 22, 2017

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
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.

Main topics:
Exa-Scale architectures, supercomputers, scheduling, performance
sensors, energy efficiency, task migration

Workshop papers must not exceed 6 single-spaced, double-column pages in
ACM style (including figures and references).
