Functions

dcgmReturn_t dcgmGetDeviceTopology(dcgmHandle_t pDcgmHandle, unsigned int gpuId, dcgmDeviceTopology_t *pDcgmDeviceTopology)

Gets device topology corresponding to the gpuId.

Parameters

• pDcgmHandle – IN: DCGM Handle

• gpuId – IN: GPU Id corresponding to which topology information should be fetched

• pDcgmDeviceTopology – IN/OUT: Topology information corresponding to gpuId. pDcgmDeviceTopology->version must be set to dcgmDeviceTopology_version before this call.

Returns

• DCGM_ST_OK if the call was successful.

• DCGM_ST_BADPARAM if gpuId or pDcgmDeviceTopology were not valid.

• DCGM_ST_VER_MISMATCH if pDcgmDeviceTopology->version was not set to dcgmDeviceTopology_version.

dcgmReturn_t dcgmGetGroupTopology(dcgmHandle_t pDcgmHandle, dcgmGpuGrp_t groupId, dcgmGroupTopology_t *pDcgmGroupTopology)

Gets group topology corresponding to the groupId.

Parameters

• pDcgmHandle – IN: DCGM Handle

• groupId – IN: GroupId corresponding to which topology information should be fetched

• pDcgmGroupTopology – IN/OUT: Topology information corresponding to groupId. pDcgmgroupTopology->version must be set to dcgmGroupTopology_version.

Returns

• DCGM_ST_OK if the call was successful.

• DCGM_ST_BADPARAM if groupId or pDcgmGroupTopology were not valid.

• DCGM_ST_VER_MISMATCH if pDcgmgroupTopology->version was not set to dcgmGroupTopology_version.
