6.19.2. Functions

CUresult cuDeviceGetCliqueCount(size_t *count, CUdevice dev)

Retrieves the number of fabric cliques.

Retrieves the number of fabric cliques that the device is part of.

Parameters

• count – [out] Number of fabric cliques that the device is part of.

• dev – [in] Device for which the number of fabric cliques is requested.

Returns

CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_PERMITTED, CUDA_ERROR_NOT_SUPPORTED

CUresult cuDeviceGetCliqueInfo(CUcliqueInfo *cliqueInfo, size_t *count, CUdevice dev)

Retrieves fabric clique information.

Returns the fabric clique information for the cliques that the device is a part of. User must specify the size of the cliqueInfo array in count. The same parameter count will return the actual number of entries updated in the cliqueInfo array.

Parameters

• cliqueInfo – [out] Array to store the fabric clique information.

• count – [inout] Input: Size of the cliqueInfo array. Output: Number of entries updated in the cliqueInfo array.

• dev – [in] Device for which the clique information is requested.

Returns

CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_PERMITTED, CUDA_ERROR_NOT_SUPPORTED

CUresult cuDeviceGetFabricClusterUuid(CUuuid *uuid, CUdevice dev)

Retrieves the fabric cluster UUID.

Retrieves the fabric cluster UUID for the given device.

Parameters

• uuid – [out] Fabric cluster UUID.

• dev – [in] Device for which the fabric cluster UUID is requested.

Returns

CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_PERMITTED, CUDA_ERROR_NOT_SUPPORTED
