Cluster
A group of connected computers or accelerators working together.
Example
A cluster combines many machines to train or serve a large model.
Why it matters
It combines resources when one machine is insufficient or shared operation is useful.
You'll hear it
“One machine failed, but the rest of the group is still working.”
Can you control it?
Set by the team
The people building or running the AI choose this setup. An everyday user generally needs their help to change how this part works.
Common questions
- Does adding machines always improve speed?
- No. Communication and coordination can reduce the benefit.
- Can a shared dependency affect the whole cluster?
- Yes. Common storage, networking or control services can create wider failures.
- Must every machine be identical?
- Not necessarily. Some setups combine machines with different roles or capabilities.
