In the source for the shared-memory version of MPICH (the ch_shmem device), 
the following comment is made:

/* The environment variable MPI_GLOBMEMSIZE may be used to select memsize */

It looks like this can be used to set the amount of shared memory that is
allocated for message buffers.  Is this correct?  What are the units?  Bytes?

Thanks in advance,
Greg
