it actually fails there. The pp.x code cannot (yet) perform the
second step, i.e. writing to file in the required format for plotting,
on more than one processor. It needs to be fixed

it is already done only if you are executing the first part, i.e.
extracting the required quantity from data files. You may 
however skip the first part and read the required quantity
from an intermediate file. This is useful in some circumstances.
