Object            : Bench program to verify functionalities and 
                    performances of some new Fortran 95 
                    constructions.

Installation: get "benchs_F95.tar" file from our IDRIS Web server at URL : 
------------ 
    http://www.idris.fr/data/publications/F95/test_F95_french.html
    Execute the command: tar -xvf benchs_F95.tar which builds a new 
    directory "benchs_F95" under which you'll find Fortran 95 sources 
    with several modules and the main program "benchs_F95.f90". 
    You'll also find a Makefile and a REAME file.

Type: monoprocessor code
----

Portability: these tests only use standard Fortran 95 functions
-----------  (90 standard insufficient) and optionally the blas function
             DGEMM.

Compilation/link: make [machine-type]
----------------
    The Makefile in this directory can be used to build both in sequence 
    if your system is one of the supported machines and no modifications 
    are necessary to the makefiles.  To build executable NEdit
    from this directory, issue the command: "make <machine-type>"; where
    <machine-type> is one of suffixes of a Makefile in the "benchs_F95"
    directory.
    For example, to build the IBM aix version, type: make sgi

    If everything works properly, this will produce an executable called 
    benchs_F95.

    Note : the makefiles consist of two parts, a machine dependent part 
    and a machine independent part.  The machine dependent makefiles
    can be found in the "Makefile.machine-type" files, and contain 
    machine specific information. They invoke a common machine 
    independent part called "makefile.common". 
 
    To know the list of available "machine-types", use the make command
    without any argument. For example type: make
    which returns:  Please specify one of these targets:
                    aix        cross_nec  default    nec ...

     - If your "machine-type" is not part of it, try "default" or add
       your own file "Makefile.your_type_mach" adapting one of the
       existing specific files.

     - "cross-nec" can be used to do a NEC-SX-5 cross-compilation on a
       SGI front machine.
                
Compilation time: less than one minute on IDRIS present machines
----------------

Execution time: less than one minute on IDRIS present machines
--------------

Execution: ./benchs_F95 > benchs_F95.out 2>&1
---------
            Note : due to memory interactive limitations, it is sometimes
            necessary to execute it in batch mode.
          
Adaptation: 
----------
  (1) to modify the memory size, you can change the default value (1000) 
      of the symbolic constant "ordre" in "mod_matrice.f90" (the program 
      allocates an (ordre x ordre) real bi-dimensionned array).

  (2) if you do not want to compare the MATMUL intrinsic Fortran subroutine
      to the blas DGEMM function, set the blas variable to ".false." in
      "mod_matrice.f90"
