Question for current maintainers: ./README: new release?

Also:

* Moving out eompi & eoserial modules (issue #2).

* Correction of the errors when executing "make doc" command.

* Adding a solution for the conflicting headers problem (see the two CMake Cache
 Values: PROJECT_TAG & PROJECT_HRS_INSTALL_SUBPATH) (issue #1)

* Header inclusions:
        ** src: changing absolute paths into relative paths ('#include <...>' -> '#include "..."')
        ** test, tutorial: changing relative paths into absolute paths ('#include "..."' -> '#include <...>')

* Moving out some scripts from EDO -> to the root

* Add a new script for compilation and installation (see build_gcc_linux_install)

* Compilation with uBLAS library or EDO module: now ok

* Minor modifications on README & INSTALL files

* Comment eompi failed tests with no end

README

To launch a set of experiments with t-mpi-distrib-exp:

  1. Compile it:

    mpic++ -o distrib-exp t-mpi-distrib-exp.cpp -I../../src/ -I../../src/mpi/ -DWITH_MPI -L ../../../build/eo/lib/ -leoutils -leo -leompi -leoserial

  2. Generate the experiments, thanks to the script gen-xp.py This script will guide you and ask you for all experiments. The prefix is used in the results filenames. You may want to modify the name of the experiments file (default value: "experiments.json") or the pattern of the results files. However, you have to ensure that the pattern is an one-to-one function of the parameters, otherwise some results could be lost.

  3. Launch the t-mpi-distrib-exp program with mpirun: For 4 cores (= 1 master + 3 workers) mpirun -np 4 ./t-mpi-distrib-exp --use-experiment-file=1 --experiment-file=/home/eodev/eo/test/mpi/experiments.json

For 16 cores (= 1 master + 15 workers) mpirun -np 5 ./t-mpi-distrib-exp --use-experiment-file=1 --experiment-file=/home/eodev/eo/test/mpi/experiments.json

  1. The program will generate the results of the experiments, as txt files. There is one result file for each run of each experiment.
