What exactly are you asking? You want to write a program, by all means, write one, and if you would like feedback on it, folks will be happy to offer commentary.
If you want to know "how" to go about writing your own program, well, just pop open a text editor or an IDE, and start writing.

Maybe if you expand upon the question, people can offer some better suggestions, more along the lines of what you want.

Hi -

Writing a "hello world" in C is a good thing - any good textbook will get you started.

Writing parallel applications for an MPI cluster is a very different thing. You might want to consider this book:

The Art of Concurrency, Clay Beshears

You can also find many tutorials on-line.

PS:
On a smaller scale, there are a number of interesting efforts to write parallel programs for GPUs. Besides MPI (large scale), you might also be interested in CUDA (micro-scale):

Sorry, still no idea what you're asking...your posts are almost impossible to understand.

As other have said...if you want to write a program, open an editor, and start writing.
