Known issues:

1. When --use-event-timer option is used on some AMD GPUs, platform returns zero time on event.
   As a result, inf is displayed sometimes

2. Not yet tested on mac. There might be some minor compilation issues

TODO:

1. Integer compute tests are implemented. Currently there is some problem in compiling kernels
    on intel platform. So this test has been disabled

2. Need to implement local memory bandwidth test
