\begin{objectif}
This task deals with the COACH HPC feature that consists in accelerating an existing
application running on a PC by migrating critical parts into a SoC implemented on an
FPGA plugged to the PC PCI/X bus (figures~\ref{coach-flow} and \ref{archi-hpc}).
It consists in:
\begin{itemize}
\item Specifying and implementing the communication schemes between the software
  part running on the PC and the FPGA-SoC.
\item Providing a performance analysis tool helping user in the HPC partitioning
  (figure~\ref{archi-hpc}).
\item Providing support for configuration of the FPGA in order to set up the HPC environment.
\end{itemize}
The low level hardware transmission support will be the PCI/X bus which allows high bit-rate
transfers. The reasons of this choice are that both \altera and \xilinx provide PCI/X IP for
their FPGA and that GPU HPC softwares use also it.
%This will allow us at least to be inspired by GPU communication schemes and may be to reuse
%parts of the GPU softwares.

        This deliverable groups all the software components to implement the
        HPC communication API (\NOVERShpcCommApi).
        \Supmc will develop the Linux part (a C library and a LINUX module),
        \Stima will develop the FPGA-SoC part (a DNA driver),
        \Sbull will check this implementation on its demonstrator (\NOVERSbullAppSpecification).

\subtask{HPC environment set up}
% It also includes appropriate SoC-FPGA OS drivers and a modification of the profiling library.
     \begin{livrable}
     \itemL{18}{36}{x}{\Stima}{Support for HPC \ganttlf environment set up}{0:3:3}
      Modification of the CSG software to set-up the HPC environment.
      The objective is to run easily HPC application and the main features are:
