Dear QE users,
                         I am trying to see how the runtime scales with
number of processors. I did the same calculation using one node with eight
processors on one cluster and 8 nodes with total 56 processors on other
cluster but the time does not seem to scale linearly with the number of
processors. Can anybody give me an idea how does the time scale with number
of processors.
Thanks a lot in advance.
