Function Documentation

◆ get_mem_perf_info()

MemPerfInfos sham::details::get_mem_perf_info ( )

Retrieve the memory performance information.

Returns: A MemPerfInfos object containing the memory performance data.

Definition at line 123 of file internal_alloc.cpp.

Here is the call graph for this function:

◆ internal_alloc()

template<USMKindTarget target>

void * sham::details::internal_alloc	(	size_t	sz,
		const std::shared_ptr< DeviceScheduler > &	dev_sched,
		std::optional< size_t >	alignment
	)

Allocate a USM pointer with at least the given size in bytes.

Parameters

sz	The minimum size of the USM pointer in bytes.
dev_sched	The SYCL queue used to allocate the USM pointer.
alignment	The alignment of the USM pointer (optional).

Returns: A pointer to the allocated USM memory.

Definition at line 178 of file internal_alloc.cpp.

◆ internal_free()

template<USMKindTarget target>

void sham::details::internal_free	(	void *	usm_ptr,
		size_t	sz,
		const std::shared_ptr< DeviceScheduler > &	dev_sched
	)

Free a USM pointer.

Parameters

usm_ptr	The pointer to free.
sz	The size of the USM pointer in bytes.
dev_sched	The SYCL queue used to free the USM pointer.

Definition at line 147 of file internal_alloc.cpp.

◆ log_mem_perf_info()

std::string sham::details::log_mem_perf_info ( const std::shared_ptr< DeviceScheduler > & dev_sched )

Definition at line 131 of file internal_alloc.cpp.

◆ reset_mem_info_max()

void sham::details::reset_mem_info_max ( )

Reset the memory information for the maximum allocated bytes.
