gs_device_shmem Module Reference

Defines GPU aware MPI gather-scatter communication.

Data Types
type	gs_device_shmem_buf_t
	Buffers for non-blocking communication and packing/unpacking. More...
type	gs_device_shmem_t
	Gather-scatter communication using device SHMEM. The arrays are indexed per PE like send_pe and @ recv_pe. More...
