[gpaw-users] kpt parallel use

[Torsten Hahn]

Dear Users,

can someone point me to an basic example on how to deal correct with kpt / spin parallelization in GPAW? 

As i understand, from an calculator calc = GPAW(...)

i get the 

calc.wfs.kpt_u list.

if i iterate over that list

result = np.zeros(len(kpt_u), dtype='d')

for kpt in kpt_u:
    # do something to calculate result using kpt, e.g.
    result = kpt.C_nM ...
    

Do i have to "collect" (<- i do not know if this is the correct syntax) result on the master? As i understand if i do it like above the array result is scattered over the nodes?

Best regards,
Torsten.
