[Pw_forum] stability of fftw3 in qe-3.1

[Sergey Lisenkov]

 Dear developers,

  I tried to run a simple calculation of SrRuO3 using pwscf 3.1 version linked 
with fftw-3.1.1 library on intel xeon em64t cluster. Code crashed before the 
first scf iteration (I see that integrated charge is a very huge value). But 
when I used the same pwscf version but linked with fftw2 library, calculation 
is going smoothly. It seems that it is fftw issue. Is it safe way to use fftw3 
library ?

  Thanks,
    Sergey
