[OMPI users] Limitation of MPI_BCAST

[William Au]

Hi,

I am using openmpi 1.6 and when I tried to send a large array through MPI_BCAST
in fortran. The number of count is larger than 3 billions. Although I compiled 
openmpi and
my code with the option to declare my fortran integer as 64 bit long in linux. 
I found out
that fortran pbcast_f.c will cast my *count to integer to call the c code 
MPI_Bcast

  *ierr = OMPI_INT_2_FINT(MPI_Bcast(OMPI_F2C_BOTTOM(buffer),
                                            OMPI_FINT_2_INT(*count),

So my question is, is it possible to bcast more than MAX_INT count of data_type 
in
openmpi?

Thanks.

Regards,

William
