                      CALL  FOR  PAPERS

      3rd Workshop on Co-Scheduling of HPC Applications
                        (COSH 2018)

              Manchester, UK, January 23, 2018
                  together with HiPEAC 2018



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 exascale systems with millions of compute cores. Many of
today's highly scalable applications will not be able to utilise an
exascale 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.

Thus, submitted papers should cover one or more items from the
following research areas:
* novel scheduling strategies using co-scheduling
* co-scheduling towards energy efficiency
* case studies involving co-scheduling
* application characterisation for co-scheduling
* using performance sensors to guide co-scheduling
* resource re-assignment / task migration enabling co-scheduling
* throughput studies for supercomputers using co-scheduling
