Subject: Sayantan :Weekly Report #2

1. Implemented a function to find the optimum local work group size in
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.

1. More experimentation and optimization.
