Hi,
just a quick question: is fftw3 already supported with newcore?
I have the impression that it is not detected properly.
system_info.py for the "old" scipy_distutils does some effort
to figure out about fftw3:
class fftw_info(system_info):
#variables to override
section = 'fftw'
dir_env_var = 'FFTW'
notfounderror = FFTWNotFoundError
ver_info = [ { 'name':'fftw3',
'libs':['fftw3'],
'includes':['fftw3.h'],
'macros':[('SCIPY_FFTW3_H',None)]},
{ 'name':'fftw2',
'libs':['rfftw', 'fftw'],
'includes':['fftw.h','rfftw.h'],
'macros':[('SCIPY_FFTW_H',None)]}]
which is not present in the newcore system_info
It would be nice if newscipy could support fftw3 as well,
as fftw3 performs by approx. a factor of 3 faster than fftw2
on the opteron!
BTW: did anyone of you ever compare the speed of the wrapped fftw
with the mflops as given by the
benchmarks on http://www.fftw.org/speed/ ?
Best,
Arnd
