To run single-threaded test, execute the following command:
$ bench -opatient -s [i|o][r|c][f|b]<size>
Where,
i/o means in-place or out-of-place. Out of place is the default.
r/c means real or complex transform. Complex is the default.
f/b means forward or backward transform. Forward is the default.
<size> is an arbitrary multidimensional sequence of integers separated by the character ‘x’.
To run multi-threaded test, execute the following command:
$ bench -opatient -onthreads=N -s [i|o][r|c][f|b]<size>
Where, N is number of threads.
