13.5.2 Various Parallelizing Technologies

To understand the issues involved in parallelizing codes and the difference between ASPAR and other similar tools, we must examine two basic issues involved in parallelizing code: the local and the global views.

The local view of a piece of code is restricted to one or more loops or similar constructs upon which particular optimizations are to be applied. In this case little attention is paid to the larger scale of the application.

The global view of the program is one in which the characteristics of a particular piece of data or a function are viewed as a part of the complete algorithm. The impact of operating on one item is then considered in the context of the entire application. We believe that ASPAR offers a completely new approach to both views.
