cs_halo_hip_pack_send_buffer()

void cs_halo_hip_pack_send_buffer	(	const cs_halo_t *	halo,
		hipStream_t	stream,
		cs_halo_type_t	sync_mode,
		cs_datatype_t	data_type,
		cs_lnum_t	stride,
		const void *	val,
		void *	send_buffer
	)

Pack cs_real_t halo data to send into dense buffer, using HIP.

A local state and/or buffer may be provided, or the default (global) state and buffer will be used. If provided explicitely, the buffer must be of sufficient size.

Parameters

[in]	halo	pointer to halo structure
[in]	stream	associated HIP stream
[in]	sync_mode	synchronization mode (standard or extended)
[in]	data_type	data type
[in]	stride	number of (interlaced) values by entity
[in]	var	pointer to value array (device)
[out]	send_buffer	pointer to send buffer, NULL for global buffer
