You can download KWSN Knabench 1.43 Benchmark Package from the download section of this site. Then follow the advice in readme.

I tested the latest version. The results is  different from the optimised CPU application.

During the test, there is a vast display of the FFT time, it makes the PC not very responsive. Is it intended? The GPU speed is very slow, is it due to the display?
