I am trying to use the MPI_Register_datarep functionnality with 
mpich-3.2, but while executing, I have this error:

ERROR Returned by MPI: 67148823
ERROR_string Returned by MPI: An error occurred in a user-defined data 
conversion function, error stack:
MPI_REGISTER_DATAREP(108): Read and Write datarep conversions are 
currently not supported by MPI-IO
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

I have configured mpich-3.2 with: ./configure 
--prefix=/opt/mpich-3.2_ch3sock --with-device=ch3:sock

Is there anything I have to do to be able to use this functionality?
