Dear QE developers, could anyone explain to me in a few words a difference between inter_pool_comm and intra_pool_comm variables. I am not really familiar with MPI, but I need to sum some variable over k-points. Should I use mp_sum(variable_name,inter_pool_comm) or mp_sum(variable_name,intra_pool_comm)?
Does mp_sum take into account k-point weights? (As I understood from the source this routine is used for summation over k-points?) Thank you in advance. -- Best regards, Dmitry Korotin Ph. D. Student, Institute of Metal Physics S. Kovalevskaya, 18 620041 Ekaterinburg GSP-170 Russia
