This module contains subroutines to initialize MPI buffers between cpu myrank and its neighbor cpus.

Public Member Functions
subroutine, public	init_mpi_buffers ()
	This subroutine searches for common GLL nodes between cpu myrank and its neighbor cpus. Send and receive buffers are filled only with unique GLLs (i.e., no duplicated GLL are present in MPI buffers). More...

Private Member Functions
subroutine, private	create_gll_buffer_recv (gll_coord_send, gll_coord_recv, ngll, gll_recv, gll_send, max_size)
	This subroutine creates GLLs buffers received by cpu myrank from other cpus. Identical GLLs between connected cpus are found by computing minimal distance among GLLs. Two GLLs from different cpus with the smallest minimal distance are supposed to be identical. More...

subroutine, private	remove_duplicate (x1, n, x3, m)
	This subroutine removes duplicated GLLs between cpu myrank and its connected cpus. More...
