cuda.bindings.nvml.device_get_handle_by_pci_bus_id_v2#

cuda.bindings.nvml.device_get_handle_by_pci_bus_id_v2(pci_bus_id) → intptr_t#

Acquire the handle for a particular device, based on its PCI bus id.

For all products. This value corresponds to the nvmlPciInfo_t.busId returned by device_get_pci_info_v3(). Starting from NVML 5, this API causes NVML to initialize the target GPU NVML may initialize additional GPUs if:.

The target GPU is an SLI slave.

Parameters:: pci_bus_id (str) – The PCI bus id of the target GPU Accept the following formats (all numbers in hexadecimal): domain:bus:device.function in format x:x:x.x domain:bus:device in format x:x:x bus:device.function in format x:x.x.
Returns:: Reference in which to return the device handle.
Return type:: intptr_t

Note

NVML 4.304 and older version of nvmlDeviceGetHandleByPciBusId”_v1” returns NVML_ERROR_NOT_FOUND instead of NVML_ERROR_NO_PERMISSION.
