Most of the loops that could be replaced by
do concurrent
have been.On my laptop, here are the timings I gets:
Legacy code:
bench01_zfft
: 3.19 secondsbench02_zfft
: 4.10 secondsbench03_dfft
: 1.80 secondsDo-concurrent code:
bench01_zfft
: 2.26 seconds (1.4x speedup)bench02_zfft
: 2.90 seconds (1.4x speedup)bench03_dfft
: 1.50 seconds (1.2x speedup)Both codes are compiled with
gfortran 13.3
. The speed-ups are obviously to be taken with a grain of salt. We would need to do a proper performances analysis with sequences of varying lengths. Still, it's pretty nice I believe.ping @perazz @zoziha

intent_specs
one and should be merge after the latter.
