Processing Node

The SPQR framework relies on two different server node types:

• Processing Node
• [Resource Manager](Resource Manager)

The first one handles all computation jobs executed from within previously instantiated micro pipelines. The latter keeps track of all SPQR cluster nodes (processing nodes) and pipelines distributed among those nodes.

This wiki page focuses on the processing node and its internals.

Operation Mode

The processing node supports two different operation modes:

• cluster mode
• local/standalone mode

The latter allows to set up a single node environment eg. for testing or single pipeline deployments. The former lets the node register itself with a clustered environment and receives all deployments from the resource manager.
