A single physical server machine in the data center. Each host
has its associated compute resources such as accelerators. The number and
configuration of these compute resources depend on the machine family.
Virtual machine (VM) instances are provisioned on top of a physical host.
For A3 Ultra and A4 machines a cluster provides a common, non-blocking
network fabric for your blocks of accelerator capacity. Within a cluster,
the east to west networking is non-blocking for the entire collection of blocks.
Each cluster is globally unique.
A resource request that allocates your accelerator
resources physically close to each other to minimize network hops and optimize
for the lowest latency.
