@nprofile1q... You should write a book, "Using GPUs to massively speed up your C/C++ code" - targeted for C/C++ programmers.
I'd pre-order it for sure.
Chapter 1 - GPUs for idiots and/or programmers too busy and/or lazy - minimal code to speed up your hello world app by calculating PI to 100 digits. Before/after comparison.
I wonder if you could use a GPU to speed up a database, like for searching or joining tables, creating/comparing search hashes and the like...
