What does "mpi_bcast(1, ...)" mean ?

[mnakao@ccs_tsukuba_ac_jp]

I'm trying to run CESM 1.1.1 on the K computer by using Fujitsu compiler.But, I encounter the issue of mpi_bcast.For example, in (CESMROOT)/models/utils/pio/piodarray.F90,---
call mpi_bcast(1, 1, mpi_integer, ios%compmaster, ios%intercomm, ierr)call mpi_bcast(MPI_REAL4, 1, mpi_integer, ios%compmaster, ios%intercomm, ierr)---In Fujitsu compiler, the first argument of mpi_bcast() must be a valiable.Defined vaule is not used, but Intel MPI compiler or mvapich is OK. To start with, what does "mpi_bcast(1, ...)" mean ?I do not think that these lines have meanings.May I make these lines comment out ? Thanks,

This broadcast is sent from tasks in this part of the code but recieved by tasks in pio_msg_callbacks.F90 (variable fillv at around line 238).This part of the code is not currently used in cesm, you can safely comment it out, I will update to use a variable instead of a constant in the next tag.

Dear jedwards, I understand that. Thanks a lot.

I've taken care of this in the latest PIO tag 1.7.0.   It should now satisfy the requirements of mpi.mod.
