[Pw_forum] K-point parallelization

[Sergey Lisenkov]

 Dear PWscf authors,

  I am wondering does k-point parallelization work very well on any platform? I have noticed that on our cluster (IBM Blade PPC970 - power4+) PW code works slowly with k-point parallelization in respect to without k-point parallelization. Does it depend on the platform? 

  Thanks,
    Sergey
