A feature of a programming language for a parallel processing system which allows or forces the programmer to annotate his program to indicate which parts should be executed as independent parallel tasks. This is obviously more work for the programmer than a system with implicit parallelism (where the system decides automatically which parts to run in parallel) but may allow higher performance.
