Symmetric buffer for one direction of OpenSHMEM communication. More...

Collaboration diagram for gs_shmem::gs_shmem_buf_t:

Public Member Functions
procedure, pass(this)	init (this, pe_order, dof_stack)
	Allocate symmetric memory and per-neighbor bookkeeping for one direction of communication.
procedure, pass(this)	free (this)
	Release symmetric memory and bookkeeping.

Public Attributes
integer, dimension(:), allocatable	ndofs
	Number of dofs per neighbor.
integer, dimension(:), allocatable	offset
	Local offset in this buffer for each neighbor.
integer, dimension(:), allocatable	remote_offset
	For send_buf: offset in the remote PE's recv buffer where our data should land. Unused for recv_buf.
integer	total = 0
	Total number of dofs in this buffer on this PE.
integer	max_total = 0
	Maximum total across all PEs (size of the symmetric allocation)
type(c_ptr)	buf_ptr = C_NULL_PTR
	Raw pointer to the symmetric buffer returned by shmem_malloc.
