Abstract: A computer implemented method for defining, organizing, and analyzing systems and the connections, or relationships, between the systems, in a flexible manner according to a user's focus, perspective, and desired level of detail. A set of systems is selected by a user. A set of attributes by which to distinguish the systems is selected by the user. The systems are grouped according to the values for the selected attributes, thereby forming a taxonomy tree. A user then selects one or more resources that are potentially produced by, i.e., flow from, or consumed by, i.e., flow to, one or more of the systems of interest. A hypercube data structure is created that defines between which systems the resources flow. Utilizing the taxonomy tree, the hypercube further summarizes resource flows between parent systems for which resource flows are defined between their corresponding child systems.

Abstract: A method of addressing an arbitrary global element stored within a first local memory associated with a first processing device is described for a distributed memory computers which includes a multiplicity of processing devices each having an associated base pointer or memory location and an associated memory, each of the local memories storing a subarray of a global array, each subarray having a subarray base element, each of the memories having a subarray base element memory address with said global array including a multiplicity of global elements.
