5.47. nvmlPlatformInfo_v1_t Struct Reference

[Device Enums]

Deprecated

The nvmlPlatformInfo_v1_t will be deprecated in the subsequent releases. Use nvmlPlatformInfo_v2_t

Structure to store platform information

Public Variables

unsigned char  chassisPhysicalSlotNumber
The slot number in the rack containing this GPU (includes switches).
unsigned char  computeSlotIndex
The index within the compute slots in the rack containing this GPU (does not include switches).
unsigned char  ibGuid[16]
Infiniband GUID reported by platform (for Blackwell, ibGuid is 8 bytes so indices 8-15 are zero).
unsigned char  moduleId
ID of this GPU within the node.
unsigned char  nodeIndex
Index of the node within the slot containing this GPU.
unsigned char  peerType
Platform indicated NVLink-peer type (e.g. switch present or not).
unsigned char  rackGuid[16]
GUID of the rack containing this GPU (for Blackwell rackGuid is 13 bytes so indices 13-15 are zero).
unsigned int  version
the API version number
