[Wien] MPI problem for LAPW2

[Duy Le]

Dear Wien2kers,

I managed successfully k-parallel. I have now to deal with a very big system
that definitely needs fully mpi wien2k. The compilation was successful.
I can run mpi with lapw0, lapw1, and lapw2. However, lapw2 can run without
problem with certain number of PROCESSORS PER MPI JOB (in both cases: fully
mpi and/or hybrid k-parallel+mpi). Those certain numbers are 3 and 7. If I
try to run with other numbers of PROCESSORS PER MPI JOB, it gives me an
message like below. This problem doesn't occur with lapw0 and lapw1. If any
of you could give me some suggestion of fixing this problem, it would be
appreciated.
