Interface provided:

1. comm_ivglrsum
2. comm_ibcastn

Function Documentation

comm_ibcastn()

subroutine comm_ibcastn	(	integer, dimension(nl)	buf,
		integer	nl,
		integer	sid
	)

Broadcast integer array from specified process.

This routine is simillar to lbcast and bcast from comm_mpi.f

Parameters

[in,out]	buf	array to be broadcased
[in]	nl	buffer length
[in]	sid	broadcasting process id

		integer	nl
	)

Global MPI scan for integer array.

This routine is simillar to igl_running_sum and i8gl_running_sum from comm_mpi.f

Parameters
