Implemented a function to find the optimum local work group size in opencl-mscash2. 2. The following are not an accomplishment in strict sense but more of a kind of experiment and the results should be helpful in future: a. rotate() function caused huge performance drop on 7970 on bull. I replaced the rotate function with a macro resulting in nearly 50% performance improvement. With this change the opencl-mscash2 produces around 72-73K real/s. b. other cards(4890,570) I tested don't have such issues with rotate(). c. Vectorization of the code caused small(2-3%) performance drop on 7970 and 570. Priorities: 1. More experimentation and optimization. Content of type "text/html" skipped
