CUDA_DEVICE_DEPRECATED (3)

NAME

Device Management [DEPRECATED] -

Functions

CUresult cuDeviceComputeCapability (int *major, int *minor, CUdevice dev)
Returns the compute capability of the device.
CUresult cuDeviceGetProperties (CUdevprop *prop, CUdevice dev)
Returns properties for a selected device.

Detailed Description

\brief deprecated device management functions of the low-level CUDA driver API (cuda.h)

This section describes the device management functions of the low-level CUDA driver application programming interface.

Function Documentation

CUresult cuDeviceComputeCapability (int * major, int * minor, CUdevice dev)

Deprecated

This function was deprecated as of CUDA 5.0 and its functionality superseded by cuDeviceGetAttribute().

Returns in *major and *minor the major and minor revision numbers that define the compute capability of the device dev.

Parameters:

major - Major revision number
minor - Minor revision number
dev - Device handle

Returns:

CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_DEVICE

Note:

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

CUresult cuDeviceGetProperties (CUdevprop * prop, CUdevice dev)

Deprecated

This function was deprecated as of CUDA 5.0 and replaced by cuDeviceGetAttribute().

Returns in *prop the properties of device dev. The CUdevprop structure is defined as:

     typedef struct CUdevprop_st {
     int maxThreadsPerBlock;
     int maxThreadsDim[3];
     int maxGridSize[3];
     int sharedMemPerBlock;
     int totalConstantMemory;
     int SIMDWidth;
     int memPitch;
     int regsPerBlock;
     int clockRate;
     int textureAlign
  } CUdevprop;

 where:

*

maxThreadsPerBlock is the maximum number of threads per block;

*

maxThreadsDim[3] is the maximum sizes of each dimension of a block;

*

maxGridSize[3] is the maximum sizes of each dimension of a grid;

*

sharedMemPerBlock is the total amount of shared memory available per block in bytes;

*

totalConstantMemory is the total amount of constant memory available on the device in bytes;

*

SIMDWidth is the warp size;

*

memPitch is the maximum pitch allowed by the memory copy functions that involve memory regions allocated through cuMemAllocPitch();

*

regsPerBlock is the total number of registers available per block;

*

clockRate is the clock frequency in kilohertz;

*

textureAlign is the alignment requirement; texture base addresses that are aligned to textureAlign bytes do not need an offset applied to texture fetches.

Parameters:

prop - Returned properties of device
dev - Device to get properties for

Returns:

CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_DEVICE

Note:

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