For my student job at the university I was given the task to vectorize a given program that simulated diffraction. It was required to run best on CPUs and should run using OpenCL. I had some of that running on it, also, but without OpenCL. The only problem was that each thread required quite large amounts of memory when you were simulating longer time durations, so it was not well suited for that card.

Later on I implemented a generator for surprising strings and tried multiple things to optimize my code on that. After two months or so I dismounted the machine and never used the card again, since.

Aside from minor things I never used the card nearly to its potential. So when I saw this thread, I liked the idea of reviving the card.
