Member Function Documentation

end_timeline_event()

void sham::gpu_core_timeline_profilier::acc::end_timeline_event ( const local_access_t &  acc ) const

inline

Finish a timeline event.

This function must be called at the end of the kernel to register the resulting events.

Parameters

[in]

acc

The local accessor for the current work-group.

Definition at line 251 of file gpu_core_timeline.hpp.

Here is the call graph for this function:

init_timeline_event()

void sham::gpu_core_timeline_profilier::acc::init_timeline_event ( sycl::nd_item< 1 >  item, const local_access_t &  acc  ) const

inline

Initialize a timeline event.

This function must be called at the beginning of the kernel to register a new timeline event. The function will only be executed by one thread of the work-group, and will be synchronized with the other threads of the work-group.

This function will allocate a new timeline event if there is still space available in the buffer. If the buffer is full, the function will do nothing.

The function will also set the start time of the timeline event to the current device clock.

Parameters

[in]	item	The sycl::nd_item representing the current work-group.
[in]	acc	The local accessor for the current work-group.

Definition at line 189 of file gpu_core_timeline.hpp.

Here is the call graph for this function:

start_timeline_event()

void sham::gpu_core_timeline_profilier::acc::start_timeline_event ( const local_access_t &  acc ) const

inline

Start a timeline event.

This function must be called at the start of the kernel to register to get the start time of the worker thread.

Parameters

[in]

acc

The local accessor for the current work-group.
