Communication Types

Essential characteristics of communication

• Local vs. global

  Communication with small set of tasks ("neighbors") or with many other tasks.

• Structured vs. unstructured

  Task and neighbors form a regular structure (tree, grid, ...) or arbitrary graphs.

• Static vs. dynamic

  Identity of communication partners known at compile time and does not change or depends runtime data and may be variable.

• Synchronous vs. asynchronous

  Producers/consumers execute in a coordinated fashion cooperating in data transfer or consumer may require data without cooperation of producer.
