 Dear all,

   There is a problem with PWscf code running in parallel (serial version works fine) on Itanium2 cluster, compiled with Intel8.1 compilers, mpich-gm:

1 - MPI_ALLREDUCE : Datatype is MPI_TYPE_NULL
2 - MPI_ALLREDUCE : Datatype is MPI_TYPE_NULL
3 - MPI_ALLREDUCE : Datatype is MPI_TYPE_NULL
0 - MPI_ALLREDUCE : Datatype is MPI_TYPE_NULL
[0]  Aborting program !

[1]  Aborting program !
[1] Aborting program!
[2]  Aborting program !
[2] Aborting program!
[3]  Aborting program !
[3] Aborting program!

 It should be certanly a problem of MPICH, but system admins does not believe in that, because other MPI programs work fine. So, did anybody see the same problem or know how to fix it?

  Thanks in advance,
     Sergey
