Variables
- uint64_t CUpti_ActivityNvLink2::bandwidth [inherited]
-
Banwidth of NVLink in kbytes/sec
- uint32_t CUpti_ActivityNvLink2::domainId [inherited]
-
Domain ID of NPU. On Linux, this can be queried using lspci.
- uint32_t CUpti_ActivityNvLink2::flag [inherited]
- CUpti_ActivityNvLink2::@21 CUpti_ActivityNvLink2::idDev0 [inherited]
-
If typeDev0 is CUPTI_DEV_TYPE_GPU, UUID for device 0. CUpti_ActivityDevice2. If typeDev0 is CUPTI_DEV_TYPE_NPU, struct npu for NPU.
- CUpti_ActivityNvLink2::@22 CUpti_ActivityNvLink2::idDev1 [inherited]
-
If typeDev1 is CUPTI_DEV_TYPE_GPU, UUID for device 1. CUpti_ActivityDevice2. If typeDev1 is CUPTI_DEV_TYPE_NPU, struct npu for NPU.
- uint32_t CUpti_ActivityNvLink2::index [inherited]
-
Index of the NPU. First index will always be zero.
- CUpti_ActivityKindCUpti_ActivityNvLink2::kind [inherited]
-
The activity record kind, must be CUPTI_ACTIVITY_KIND_NVLINK.
- uint32_t CUpti_ActivityNvLink2::nvlinkVersion [inherited]
-
NvLink version.
- uint32_t CUpti_ActivityNvLink2::physicalNvLinkCount [inherited]
-
Number of physical NVLinks present between two devices.
- int8_t CUpti_ActivityNvLink2::portDev0[CUPTI_MAX_NVLINK_PORTS] [inherited]
-
Port numbers for maximum 16 NVLinks connected to device 0. If typeDev0 is CUPTI_DEV_TYPE_NPU, ignore this field. In case of invalid/unknown port number, this field will be set to value CUPTI_NVLINK_INVALID_PORT. This will be used to correlate the metric values to individual physical link and attribute traffic to the logical NVLink in the topology.
- int8_t CUpti_ActivityNvLink2::portDev1[CUPTI_MAX_NVLINK_PORTS] [inherited]
-
Port numbers for maximum 16 NVLinks connected to device 1. If typeDev1 is CUPTI_DEV_TYPE_NPU, ignore this field. In case of invalid/unknown port number, this field will be set to value CUPTI_NVLINK_INVALID_PORT. This will be used to correlate the metric values to individual physical link and attribute traffic to the logical NVLink in the topology.
- CUpti_DevTypeCUpti_ActivityNvLink2::typeDev0 [inherited]
-
Type of device 0 CUpti_DevType
- CUpti_DevTypeCUpti_ActivityNvLink2::typeDev1 [inherited]
-
Type of device 1 CUpti_DevType
