NAME

Device Management [DEPRECATED] - deprecated device management functions of the low-level CUDA driver API ( cuda.h)
 

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

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This function was deprecated as of CUDA 5.0 and its functionality superseded by cuDeviceGetAttribute().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