===Task parallelism===
{{main|Task parallelism}}
Task parallelisms is the characteristic of a parallel program that "entirely different calculations can be performed on either the same or different sets of data".<ref name=Culler124>Culler et al. p.&nbsp;124.</ref> This contrasts with data parallelism, where the same calculation is performed on the same or different sets of data. Task parallelism involves the decomposition of a task into sub-tasks and then allocating each sub-task to a processor for execution. The processors would then execute these sub-tasks concurrently and often cooperatively. Task parallelism does not usually scale with the size of a problem.<ref name=Culler125>Culler et al. p.&nbsp;125.</ref>
