Composed-Views

Complex data structures (such as multi-dimensional arrays) may be stored in groups of minipages. It might be helpful for an application to access these structures using different views at different stages. Higher level views may be associated with groups of lower level views, or groups of minipages. Obviously, the access permissions to such a composed-view should be set to the least of the access permissions of its components.

One good example where composed-views (or compiler work) can be used is the chunking-level in WATER, as discussed in Section 4.4. Clearly, the read phase in WATER could benefit from a coarse grain operation mode, whereas the later write phase would accelerate in a fine grain mode due to the elimination of false-sharing. Hence, replacing the current compromise by arbitration between fine-grained and coarser-grained views would speed up the computation.
