According to,the values specified in global_work_size must be evenly divisible by the corresponding values specified in local_work_size.However,I set local_work_size=256 and global_work_size=384 in my program.It debug with no error.

I am using AMD APP SDK 3.0.My questions as follows:

1. How does the driver deal with it when global_work_size can not be evenly divisible by loacl_work_size?

2. Will it cause any problem about performance degradation?
