Function Documentation

◆ __hipPopCallConfiguration()

hipError_t __hipPopCallConfiguration ( dim3 gridDim,
dim3 blockDim,
size_t *  sharedMem,
hipStream_t stream 
)

Pop configuration of a kernel launch.

Parameters
[out]gridDimgrid dimension specified as multiple of blockDim.
[out]blockDimblock dimensions specified in work-items
[out]sharedMemAmount of dynamic shared memory to allocate for this kernel. The HIP-Clang compiler provides support for extern shared declarations.
[out]streamStream where the kernel should be dispatched. May be 0, in which case the default stream is used with associated synchronization rules.

Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.

Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.

Returns
hipSuccess, hipInvalidDevice, hipErrorNotInitialized, hipErrorInvalidValue

◆ __hipPushCallConfiguration()

hipError_t __hipPushCallConfiguration ( dim3  gridDim,
dim3  blockDim,
size_t sharedMem   __dparm0,
hipStream_t stream   __dparm
)

Push configuration of a kernel launch.

Parameters
[in]gridDimgrid dimension specified as multiple of blockDim.
[in]blockDimblock dimensions specified in work-items
[in]sharedMemAmount of dynamic shared memory to allocate for this kernel. The HIP-Clang compiler provides support for extern shared declarations.
[in]streamStream where the kernel should be dispatched. May be 0, in which case the default stream is used with associated synchronization rules.

Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.

Returns
hipSuccess, hipInvalidDevice, hipErrorNotInitialized, hipErrorInvalidValue

◆ hipConfigureCall()

hipError_t hipConfigureCall ( dim3  gridDim,
dim3  blockDim,
size_t sharedMem   __dparm0,
hipStream_t stream   __dparm
)

Configure a kernel launch.

Parameters
[in]gridDimgrid dimension specified as multiple of blockDim.
[in]blockDimblock dimensions specified in work-items
[in]sharedMemAmount of dynamic shared memory to allocate for this kernel. The HIP-Clang compiler provides support for extern shared declarations.
[in]streamStream where the kernel should be dispatched. May be 0, in which case the default stream is used with associated synchronization rules.

Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.

Returns
hipSuccess, hipInvalidDevice, hipErrorNotInitialized, hipErrorInvalidValue

◆ hipDrvMemcpy2DUnaligned()

hipError_t hipDrvMemcpy2DUnaligned ( const hip_Memcpy2D pCopy)

Copies memory for 2D arrays.

Parameters
pCopy- Parameters for the memory copy
Returns
hipSuccess, hipErrorInvalidValue

◆ hipExtLaunchKernel()

hipError_t hipExtLaunchKernel ( const void *  function_address,
dim3  numBlocks,
dim3  dimBlocks,
void **  args,
size_t  sharedMemBytes,
hipStream_t  stream,
hipEvent_t  startEvent,
hipEvent_t  stopEvent,
int  flags 
)

Launches kernel from the pointer address, with arguments and shared memory on stream.

Parameters
[in]function_addresspointer to the Kernel to launch.
[in]numBlocksnumber of blocks.
[in]dimBlocksdimension of a block.
[in]argspointer to kernel arguments.
[in]sharedMemBytesAmount of dynamic shared memory to allocate for this kernel. HIP-Clang compiler provides support for extern shared declarations.
[in]streamStream where the kernel should be dispatched.
[in]startEventIf 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]stopEventIf 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. May be 0, in which case the default stream is used with associated synchronization rules.
[in]flags.The value of hipExtAnyOrderLaunch, signifies if kernel can be launched in any order.
Returns
hipSuccess, hipInvalidDevice, hipErrorNotInitialized, hipErrorInvalidValue.

◆ hipLaunchByPtr()

hipError_t hipLaunchByPtr ( const void *  func)

Launch a kernel.

Parameters
[in]funcKernel to launch.

Returns
hipSuccess, hipInvalidDevice, hipErrorNotInitialized, hipErrorInvalidValue
Parameters
[in]argPointer the argument in host memory.
[in]sizeSize of the argument.
[in]offsetOffset of the argument on the argument stack.
