[Pw_forum] ZGEMM or MATMUL for MPI environment

[Ilya Ryabinkin]

Colleagues:
I'm wondering what should I use to get the matrix product evc*S, where
   evc  = evc(npw, nbnd)
is a collection of MOs and
   S = S(nbnd, nbnd)
if my code is executed on several MPI nodes?

I see that for for nproc >1

npw is actually npw/nproc, which brings a question what is happening
in the MATMUL(evc, S)
