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?

Copy sahcuda.exe to \KWSN Knabench 1.43\Science_apps\ and run Knabench-1.43.cmd
