6.17. Fabric Clique Information

This section describes functions and data structures to retrieve fabric clique information.

Classes

struct CUcliqueInfo

Enumerations

enum CUcliqueType

Functions

CUresult cuDeviceGetCliqueCount ( size_t* count, CUdevice dev ): Retrieves the number of fabric cliques.
CUresult cuDeviceGetCliqueInfo ( CUcliqueInfo* cliqueInfo, size_t* count, CUdevice dev ): Retrieves fabric clique information.
CUresult cuDeviceGetFabricClusterUuid ( CUuuid* uuid, CUdevice dev ): Retrieves the fabric cluster UUID.

Enumerations

enum CUcliqueType

Fabric clique types

Values

CU_CLIQUE_TYPE_UNICAST_POINTER = 0: Unicast pointer clique
CU_CLIQUE_TYPE_MULTICAST_POINTER = 1: Multicast pointer clique
CU_CLIQUE_TYPE_UNICAST_LOGICAL_ENDPOINT = 2: Unicast logical endpoint clique
CU_CLIQUE_TYPE_MULTICAST_LOGICAL_ENDPOINT = 3: Multicast logical endpoint clique

Functions

CUresult cuDeviceGetCliqueCount ( size_t* count, CUdevice dev )

Retrieves the number of fabric cliques.

Parameters

count: Number of fabric cliques that the device is part of.
dev: 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

Description

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

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

Retrieves fabric clique information.

Parameters

cliqueInfo: Array to store the fabric clique information.
count: Input: Size of the cliqueInfo array. Output: Number of entries updated in the cliqueInfo array.
dev: 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

Description

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.

CUresult cuDeviceGetFabricClusterUuid ( CUuuid* uuid, CUdevice dev )

Retrieves the fabric cluster UUID.

Parameters

uuid: Fabric cluster UUID.
dev: 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

Description

Retrieves the fabric cluster UUID for the given device.
