-P flag appears to be broken in example README command

[jharlow-intel]

Summary:

It seems as though the -P flag and it's other synonyms break the fft_bench.py script for a particular command given in the README
python fft_bench.py -P -r -t 1 -d float32 -o 5 100000000

Output:

(fft-bench) harlowjo@harlowjo-mobl:~/repositories/IntelPython/fft_benchmark$ python fft_bench.py -P -r -t 1 -d float32 -o 5 100000000

TypeError: rfft() got an unexpected keyword argument 'overwrite_x'

Steps to reproduce:

I followed the README instructions nearly identically

1. conda create -n fft-bench -c intel numpy scipy
2. conda activate fft-bench
3. python fft_bench.py -P -r -t 1 -d float32 -o 5 100000000

I noticed I can run the same command without -P and it works.
Running it with --overwrite-x and --in-place caused the same error as above.

Please let me know if I did something wrong with my setup or if you need more info

The rfft does not provide in-place operation mode. Please do not use -P when compute FFT of real-value floating-point type datasets.
