Data-Flow¶

Requirements analysis¶

Requirements for a data-flow engine.

Features¶

• Parallel computation (multi-core)
• Specific timing of components/nodes
• Distribution of components/nodes over the network
• Arbitration of concurrent access on components/nodes
• Real-time capable

Skeletons¶

Skeletons we probably want to / will use in our data-flow graph:

• Pipeline
• Farm
• SPMC
• MPSC

Farm = Farm of parallel worker threads
SPMC = Single Producer, Multi Consumer - Task/Input of one node is subdevided into subtasks and passed as inputs to several nodes. (data parallelization)
MPSC = Multi Producer, Single Consumer - Outputs from several nodes are passed as input to one single node.

• Easy Usage / Convenient API
