[Q-e-developers] More on scalability of QE/CP on FERMI

[Carlo Cavazzoni]

Dear All,

please find attached a graph displaying the scalability of QE (cp code) 
on BGQ,
using the bands group parallelization (-nbgrp command line parameter).
It seems to me quite impressive, I suggest you to use it to communicate 
the performance of the code,
whenever it is possible.

best
carlo
