[Pw_forum] NEC MathKeisan

[wlyim at puccini.che.pitt.edu]

Dear all,

I am trying to test PWscf on NEC machine, using MathKeisan library. But in
the make.sys, which was generated by "configure.old sxcross", it stated
that the fft library of Mathkeisan (version <= 1.4, zzfft3d) is buggy.

I searched the forum for a while but there is not updated information 
about this issue. Does anyone know whether this fft bug has been fixed? 
Otherwise I would use jmfft.

Many thanks in advance!

Best regards,
William
