ANN: Paraffin 2.4

ANN: Paraffin 2.4

[Brad Moore]

Paraffin is a set of Ada 2005 generics that may be used to add
parallelism to iterative loops and recursive code.

Paraffin also includes a suit of useful parallel utilities that
utilize the Paraffin generics. These include generics for;
    1) generic to integrating a function in parallel
    2) generic to apply quicksort algorithm in parallel to an array
    3) generic to apply fast fourier transform to an array of data.
    4) generic Red-Black tree container that performs some operations
       in parallel.
    5) function to solve matrices using Gauss-Jordan Elimination

Paraffin 2.4 modifications include:

-  Added a reusable utility to solve a matrix of linear equations using
    Gauss-Jordan Elimination.
-  Added test_matrix test driver for parallel/sequential matrix solvers
-  Red-Black Tree containers fully implemented now.
      (Delete, and Contains calls work)
-  Split Red-Black Tree container into separate generics
    - Sequential
    - Work sharing
    - Work Seeking
    - Stack Safe Work Seeking
-  The Red Black Tree generic was previously intended mostly as a
    test driver for Paraffin Recursive generics. Now the generic has
    been completed to a state where it can be reused on its own as
    as generic container.
-  Changed use of Unchecked_Conversion for Recurse supprogram access
    to use 'Unrestricted_Access instead. This cleaned the code up
    considerably in this area. One issue to look into, is that
    'Unrestricted_Access is a non-standard attribute. It is supported
    by both GNAT and the ICC compiler however. It may not be supported
    by other Ada 2005 compilers. Unfortunately, Unchecked_Conversion in
    this case is not portable either, and may not even continue to work
    with the existing compilers, so it was thought that using
    'Unrestricted_Access was the best option for now. Will investigate
    to see if there is a possibility for a better solution, or providing
    a portable mechanism in a future version of Ada.

Thanks for providing the link, Yannick.
I had this nagging feeling that I forgot to mention something...
