Loop field types - Loop exterior fields

On iteration exterior fields.

When trying to investigate the parallelization potential of fields used in loops, I suggest the differentiation between iteration interior and iteration exterior fields, as depicted here.

Today, I want to say something about the latter field type.

From the perspective of a single iteration of a loop, there are only two different kinds of fields: The ones that are declared within the loop itself and the ones that are not. So, from this perspective, fields can either have a local character (declared within the loop iteration) or a global character (declared 'outside'). Fields, that are declared beyond the scope of a single loop iteration can either be
- method fields declared within the scope of the method containing the loop,
- object fields declared within the scope of the class instance containing the method or
- class fields declared within the scope of the class.


Knowing this we can define patterns that tell us how to turn this into parallel code.We curently develop a tool called "AutoAnalyzer" that automatically detects the different field profiles for a given application. Based on this information, we want to be able to suggest a suitable parallelization for a given method of loop.
