explicit parallelism การใช้

• In some instances, explicit parallelism may be avoided with the use of an optimizing compiler that automatically extracts the parallelism inherent to computations ( see implicit parallelism ).
• On the other side, reactive programming is a form of what could be described as " explicit parallelism ", and could therefore be beneficial for utilizing the power of parallel hardware.
• Firstly, and most importantly from a parallel language point of view, the majority ( all ? ) of parallel languages allow for either implicit or explicit parallelism-the former supports simplicity of use, whereas the later efficiency.
• This is the reason why ZPL achieves such good performance : having no parallel directives or other forms of explicit parallelism, ZPL exploits the operational trait that when aggregate computations are described in terms of arrays, many scalar operations must be ( implicitly ) performed to implement the array operations.
