With only a few seconds cpu time, the job is just in the starting phase (allocating memory, reading files, distributing data) and thus cpu-load is very low.

A few seconds later, this should reach about 100 % for each lapw1_mpi.

If we sum up the %CPU we obtain 100%, so the jobs are all at one node,
sure.
What does this mean? Maybe, machines file?
Or parallel_options in n2 wien-root?
