Reference documentation and code samples for the AI Platform Notebooks V1 API module Google::Cloud::Notebooks::V1::ExecutionTemplate::ScaleTier.
Required. Specifies the machine types, the number of replicas for workers
and parameter servers.
Constants
SCALE_TIER_UNSPECIFIED
value: 0 Unspecified Scale Tier.
BASIC
value: 1 A single worker instance. This tier is suitable for learning how to use
Cloud ML, and for experimenting with new models using small datasets.
STANDARD_1
value: 2 Many workers and a few parameter servers.
PREMIUM_1
value: 3 A large number of workers with many parameter servers.
BASIC_GPU
value: 4 A single worker instance with a K80 GPU.
BASIC_TPU
value: 5 A single worker instance with a Cloud TPU.
CUSTOM
value: 6
The CUSTOM tier is not a set tier, but rather enables you to use your
own cluster specification. When you use this tier, set values to
configure your processing cluster according to these guidelines:
You must set ExecutionTemplate.masterType to specify the type
of machine to use for your master node. This is the only required
setting.
