I compile a  WIEN2k code with  mpich2 with: ./configure --with-pm = hydra  (gforker)
 but when I run the parallel version I had the following error message:
LAPW0 END
Fatal error in MPI_Comm_size: Invalid communicator, error stack:
MPI_Comm_size(111): MPI_Comm_size(comm=0x5b, size=0x8d9d6c) failed
MPI_Comm_size(69).: Invalid communicator
cat: No match.
