Data Types
type	gs_crystal::gs_crystal_t
	Gather-scatter communication using a crystal router. More...

Modules
module	gs_crystal
	Defines crystal router gather-scatter communication.

Functions/Subroutines
subroutine	gs_crystal::gs_crystal_init (this, send_pe, recv_pe)
	Initialise crystal router based communication method See gs_comm.f90 for details.
subroutine	gs_crystal::gs_crystal_init_vec (this)
	Allocate the fused vector working and send buffers, sized for GS_VEC_NC components. Deferred to the first fused exchange, see gs_comm_t. The routing plan is shared with the scalar exchange and is not rebuilt here, so this stays rank local.
subroutine	gs_crystal::gs_crystal_free (this)
	Deallocate crystal router based communication method.
subroutine	gs_crystal::gs_crystal_nbrecv (this, tag)
	Post the receives of the first routing stage.
subroutine	gs_crystal::gs_crystal_nbsend (this, u, n, tag, deps, strm)
	Pack the shared vector and post the send of the first routing stage.
subroutine	gs_crystal::gs_crystal_nbwait (this, u, n, op, strm)
	Drive the remaining routing stages and reduce what is delivered into the shared vector.
subroutine	gs_crystal::gs_crystal_nbrecv_vec (this, tag, nc)
	Post the receives of the first routing stage, fused nc-component.
subroutine	gs_crystal::gs_crystal_nbsend_vec (this, u, n, nc, tag, deps, strm)
	Pack the shared vector and post the send of the first routing stage, fused nc-component.
subroutine	gs_crystal::gs_crystal_nbwait_vec (this, u, n, nc, op, strm)
	Drive the remaining routing stages and reduce what is delivered into the shared vector, fused nc-component.
