Node(mapping=None, *, ignore_unknown_fields=False, **kwargs)A TPU instance.
Attributes | |
|---|---|
| Name | Description |
name |
str
Output only. Immutable. The name of the TPU. |
description |
str
The user-supplied description of the TPU. Maximum of 512 characters. |
accelerator_type |
str
Optional. The type of hardware accelerators associated with this node. |
state |
google.cloud.tpu_v2.types.Node.State
Output only. The current state for the TPU Node. |
health_description |
str
Output only. If this field is populated, it contains a description of why the TPU Node is unhealthy. |
runtime_version |
str
Required. The runtime version running in the Node. |
network_config |
google.cloud.tpu_v2.types.NetworkConfig
Network configurations for the TPU node. |
cidr_block |
str
The CIDR block that the TPU node will use when selecting an IP address. This CIDR block must be a /29 block; the Compute Engine networks API forbids a smaller block, and using a larger block would be wasteful (a node can only consume one IP address). Errors will occur if the CIDR block has already been used for a currently existing TPU node, the CIDR block conflicts with any subnetworks in the user's provided network, or the provided network is peered with another network that is using that CIDR block. |
service_account |
google.cloud.tpu_v2.types.ServiceAccount
The Google Cloud Platform Service Account to be used by the TPU node VMs. If None is specified, the default compute service account will be used. |
create_time |
google.protobuf.timestamp_pb2.Timestamp
Output only. The time when the node was created. |
scheduling_config |
google.cloud.tpu_v2.types.SchedulingConfig
The scheduling options for this node. |
network_endpoints |
MutableSequence[google.cloud.tpu_v2.types.NetworkEndpoint]
Output only. The network endpoints where TPU workers can be accessed and sent work. It is recommended that runtime clients of the node reach out to the 0th entry in this map first. |
health |
google.cloud.tpu_v2.types.Node.Health
The health status of the TPU node. |
labels |
MutableMapping[str, str]
Resource labels to represent user-provided metadata. |
metadata |
MutableMapping[str, str]
Custom metadata to apply to the TPU Node. Can set startup-script and shutdown-script |
tags |
MutableSequence[str]
Tags to apply to the TPU Node. Tags are used to identify valid sources or targets for network firewalls. |
id |
int
Output only. The unique identifier for the TPU Node. |
data_disks |
MutableSequence[google.cloud.tpu_v2.types.AttachedDisk]
The additional data disks for the Node. |
api_version |
google.cloud.tpu_v2.types.Node.ApiVersion
Output only. The API version that created this Node. |
symptoms |
MutableSequence[google.cloud.tpu_v2.types.Symptom]
Output only. The Symptoms that have occurred to the TPU Node. |
shielded_instance_config |
google.cloud.tpu_v2.types.ShieldedInstanceConfig
Shielded Instance options. |
accelerator_config |
google.cloud.tpu_v2.types.AcceleratorConfig
The AccleratorConfig for the TPU Node. |
queued_resource |
str
Output only. The qualified name of the QueuedResource that requested this Node. |
multislice_node |
bool
Output only. Whether the Node belongs to a Multislice group. |
Classes
ApiVersion
ApiVersion(value)TPU API Version.
Values: API_VERSION_UNSPECIFIED (0): API version is unknown. V1_ALPHA1 (1): TPU API V1Alpha1 version. V1 (2): TPU API V1 version. V2_ALPHA1 (3): TPU API V2Alpha1 version. V2 (4): TPU API V2 version.
Health
Health(value)Health defines the status of a TPU node as reported by Health Monitor.
