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.

Thank you for sharing your work. Could you add the link to this work?
Thanks.
