space averaging in 1 dimension using MPI
Hello MPI experts,
Actually, I'm trying to find horizontal average of a velocity field "u(i,j,:)". My code is paralleled using MPI and the domain is decomposed in y and z directions (ipocess in y and jprocess in z). I tried many diffrent ways to calculate this averge but I failed. If the domain wasn't decomposed, I could simply do it in the following:
but do this averaging for a decomposed domain is troublesome for me. I'll be grateful if any one could give me some hints.
