This document will describe the work done under the PRACE-4IP extension. This
task is dedicated to provide useful information on application *performance and
energy usage* on next generation systems on the path towards exacsale. It will
be caried out running the accelerated UEABS on PCP systems to obtain energy metrics
on *OpenPower+GPU, Xeon Phi and FPGA*.
PCP systems availables
----------------------
This section describes the systems where codes owners have been granted access.
The table :ref:`table-pcp-systems` sums up systems and availability:

.. note:: More detailed information can be found for :ref:`e4_gpu`, :ref:`atos_knl`
and :ref:`maxeler_fpga` systems. It includes, hardware description,
registration procedures, and energy hardware and tool information.
Two sets of codes will be run. One will focus on giving metrics on multiple machines
for UEABS codes while the other will focus on porting specific kernels to the KNL
machine sampling energy impact on various parameters.
The table :ref:`table-code-definition` shows all codes available with UEABS
(regular and accelerated). It states for each codes, tageted architechures and BCOs.
Note that due to tight deadlines, efforts to port codes to new architechures will
have to be minimal.
