Detailed Description

----------------------------------------------------------------------------------------------—

Warning: These APIs provide access to special features of HCC compiler and are not available through the CUDA path.

launches kernel f with launch parameters and shared memory on stream with arguments passed to kernelparams or extra

Parameters

	[in[	f Kernel to launch.
[in]	gridDimX	X grid dimension specified in work-items
[in]	gridDimY	Y grid dimension specified in work-items
[in]	gridDimZ	Z grid dimension specified in work-items
[in]	blockDimX	X block dimensions specified in work-items
[in]	blockDimY	Y grid dimension specified in work-items
[in]	blockDimZ	Z grid dimension specified in work-items
[in]	sharedMemBytes	Amount of dynamic shared memory to allocate for this kernel. The kernel can access this with HIP_DYNAMIC_SHARED.
[in]	stream	Stream where the kernel should be dispatched. May be 0, in which case th default stream is used with associated synchronization rules.
[in]	kernelParams
[in]	extra	Pointer to kernel arguments. These are passed directly to the kernel and must be in the memory layout and alignment expected by the kernel.
[in]	startEvent	If non-null, specified event will be updated to track the start time of the kernel launch. The event must be created before calling this API.
[in]	stopEvent	If non-null, specified event will be updated to track the stop time of the kernel launch. The event must be created before calling this API.

Returns: hipSuccess, hipInvalidDevice, hipErrorNotInitialized, hipErrorInvalidValue

Warning: kernellParams argument is not yet implemented in HIP. Please use extra instead. Please refer to hip_porting_driver_api.md for sample usage.

HIP/ROCm actually updates the start event when the associated kernel completes.

hipError_t hipHccGetAccelerator	(	int	deviceId,
		hc::accelerator *	acc
	)

Return hc::accelerator associated with the specified deviceId.

hipError_t hipHccGetAcceleratorView	(	hipStream_t	stream,
		hc::accelerator_view **	av
	)

Return hc::accelerator_view associated with the specified stream.

If stream is 0, the accelerator_view for the default stream is returned.
