Functions

__host__ ​cudaError_t cudaConfigureCall ( dim3 gridDim, dim3 blockDim, size_t sharedMem = 0, cudaStream_t stream = 0 )

Configure a device-launch.

Parameters

gridDim

- Grid dimensions

blockDim

- Block dimensions

sharedMem

- Shared memory

stream

- Stream identifier

Returns

cudaSuccess, cudaErrorInvalidConfiguration

Deprecated

This function is deprecated as of CUDA 7.0

Description

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.

Note:

• This function uses standard default stream semantics.

• Note that this function may also return error codes from previous, asynchronous launches.

__host__ ​cudaError_t cudaLaunch ( const void* func )

Launches a device function.

Parameters

func

- Device function symbol

Returns

cudaSuccess, cudaErrorInvalidDeviceFunction, cudaErrorInvalidConfiguration, cudaErrorLaunchFailure, cudaErrorLaunchTimeout, cudaErrorLaunchOutOfResources, cudaErrorSharedObjectInitFailed, cudaErrorInvalidPtx, cudaErrorNoKernelImageForDevice, cudaErrorJitCompilerNotFound

Deprecated

This function is deprecated as of CUDA 7.0

Description

Launches the function func on the device. The parameter func must be a device function symbol. The parameter specified by func must be declared as a __global__ function. For templated functions, pass the function symbol as follows: func_name<template_arg_0,...,template_arg_N> cudaLaunch() must be preceded by a call to cudaConfigureCall() since it pops the data that was pushed by cudaConfigureCall() from the execution stack.

Note:

• Note that this function may also return error codes from previous, asynchronous launches.

• Use of a string naming a variable as the symbol paramater was removed in CUDA 5.0.

__host__ ​cudaError_t cudaSetupArgument ( const void* arg, size_t size, size_t offset )

Configure a device launch.

Parameters

arg

- Argument to push for a kernel launch

size

- Size of argument

offset

- Offset in argument stack to push new arg

Returns

cudaSuccess

Deprecated

This function is deprecated as of CUDA 7.0

Description

Pushes size bytes of the argument pointed to by arg at offset bytes from the start of the parameter passing area, which starts at offset 0. The arguments are stored in the top of the execution stack. cudaSetupArgument() must be preceded by a call to cudaConfigureCall().

Note:

Note that this function may also return error codes from previous, asynchronous launches.
