13This task pools the features dedicated to HPC system design. It is described on
14figures~\ref{coach-flow} and \ref{archi-hpc}. It consists in
15\begin{itemize}
16\item Providing a software tool that helps the HPC designer to find a good partition of the initial application
17    (figure~\ref{archi-hpc}).
18\item specification of the communication schemes between the software part running on the PC and the
19FPGA-SoC.
20\item Implementing the communication scheme at all levels: partition help, software
21implementation both on the PC and in the operating system of the FPGA-SoC, hardware.
22%\item Providing support for dynamic partial reconfiguration of \xilinx FPGA in order
23%to optimize FPGA ressource usage.
24\end{itemize}
25
26The low level hardware transmission support will be the PCI/X bus which allows high bit-rate
27transfers. The reasons of this choice are that both \altera and \xilinx provide PCI/X IP for
28their FPGA and that GPU HPC softwares use also it.
29%This will allow us at least to be inspired by GPU communication schemes and may be to reuse
30%parts of the GPU softwares.

35  \subtask{Implementation of API between PC and FPGA-SoC}
36    This \ST deals with the COACH HPC feature that consists in accelerating an existing
37    application running on a PC by migrating critical parts into a SoC implemented on an
38    FPGA plugged to the PC PCI/X bus.
39    The main steps and components of this \ST are:
40    \begin{itemize}
41      \item The definition of the communication middleware as a software API (Application
42        Programing Interface) between the application part running on the PC and the
43        application part running on the FPGA-SoC.
44      \item A software for helping the end-user to partition applications (figure~\ref{archi-hpc}).
45        This software is a library implementing the communication API with features to profile
46        the partitioned application.
47      \item The implementation of the communication API on the both sides (PC part and FPGA-SoC).
