Detailed Description

Function Documentation

◆ named_barrier_init()

template<uint8_t NbarCount>

__ESIMD_API void sycl::_V1::ext::intel::experimental::esimd::named_barrier_init ( )

Initialize number of named barriers for a kernel Available only on PVC.

Template Parameters

NbarCount - number of named barriers

Definition at line 372 of file memory.hpp.

◆ named_barrier_signal()

__ESIMD_API void sycl::_V1::ext::intel::experimental::esimd::named_barrier_signal	(	uint8_t	barrier_id,
		uint8_t	producer_consumer_mode,
		uint32_t	num_producers,
		uint32_t	num_consumers
	)

Perform signal operation for the given named barrier Available only on PVC.

Parameters

barrier_id	- named barrier id
producer_consumer_mode	- 2-bit flag to indicate if it's producer mode (0x1) or consumer mode (0x2). User must ensure the input value is set correctly and higher order bits are cleared.
num_producers	- number of producers
num_consumers	- number of consumers

Definition at line 388 of file memory.hpp.
