integer(kind(hipsuccess)) function	hipmodulelaunchkernel_ (f, gridDimX, gridDimY, gridDimZ, blockDimX, blockDimY, blockDimZ, sharedMemBytes, stream, kernelParams, extra)

Detailed Description

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 as multiple of blockDimX.
[in]	gridDimY	Y grid dimension specified as multiple of blockDimY.
[in]	gridDimZ	Z grid dimension specified as multiple of blockDimZ.
[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 HIP-Clang compiler provides support for extern shared declarations.
[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.

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.
