24 Module Documentation 4.7 Execution Control Functions • cudaError_t cudaConfigureCall (dim3 gridDim, dim3 blockDim, size_t sharedMem, cudaStream_t stream) Configure a device-launch. • cudaError_t cudaFuncGetAttributes (struct cudaFuncAttributes ∗attr, const char ∗func) Find out attributes for a given function. • cudaError_t cudaLaunch (const char ∗entry) Launches a device function. • cudaError_t cudaSetDoubleForDevice (double ∗d) Converts a double argument to be executed on a device. • cudaError_t cudaSetDoubleForHost (double ∗d) Converts a double argument after execution on a device. • cudaError_t cudaSetupArgument (const void ∗arg, size_t size, size_t offset) Configure a device launch. 4.7.1 Detailed Description This section describes the execution control functions of the CUDA runtime application programming interface. 4.7.2 Function Documentation 4.7.2.1 cudaError_t cudaConfigureCall (dim3 gridDim, dim3 blockDim, size_t sharedMem, cudaStream_t stream) Specifies the grid and block dimensions for the device call to be executed similar to the execution configuration syntax. cudaConfigureCall() is stack based. Each call pushes data on top of an execution stack. This data contains the dimension for the grid and thread blocks, together with any arguments for the call. Parameters: gridDim - Grid dimensions blockDim - Block dimensions sharedMem - Shared memory stream - Stream identifier Returns: Note: cudaSuccess, cudaErrorInvalidConfiguration Note that this function may also return error codes from previous, asynchronous launches.

The parameter specified by func must be declared as a __global__ function. The fetched attributes are placed in attr. If the specified function does not exist, then cudaErrorInvalidDeviceFunction is returned. Parameters: attr - Return pointer to function’s attributes func - Function to get attributes of Returns: Note: See also: cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidDeviceFunction Note that this function may also return error codes from previous, asynchronous launches. cudaConfigureCall, cudaFuncGetAttributes (C++ API), cudaLaunch (C API), cudaSetDoubleForDevice, cudaSet- DoubleForHost, cudaSetupArgument (C API) 4.7.2.3 cudaError_t cudaLaunch (const char ∗ entry) Launches the function entry on the device. The parameter entry must be a character string naming a function that executes on the device. The parameter specified by entry must be declared as a __global__ function. cudaLaunch() must be preceded by a call to cudaConfigureCall() since it pops the data that was pushed by cudaConfigureCall() from the execution stack. Parameters: entry - Device char string naming device function to execute Returns: Note: cudaSuccess, cudaErrorInvalidDeviceFunction, cudaErrorInvalidConfiguration, cudaErrorLaunchFailure, cudaErrorPriorLaunchFailure, cudaErrorLaunchTimeout, cudaErrorLaunchOutOfResources See also: Note that this function may also return error codes from previous, asynchronous launches. cudaConfigureCall, cudaFuncGetAttributes (C API), cudaLaunch (C++ API), cudaSetDoubleForDevice, cudaSet- DoubleForHost, cudaSetupArgument (C API) Generated for NVIDIA CUDA Library by Doxygen
