Functions

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

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.

Description

Gets device topology corresponding to the gpuId.

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

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.

Description

Gets group topology corresponding to the groupId.
