Metacomputing infrastructures couple multiple clusters (or MPPs) via wide-area networks. A major problem in programming parallel applications for such platforms is their hierarchi...
Abstract. Clocks are a mechanism for providing synchronization barriers in concurrent programming languages. They are usually implemented using primitive communication mechanisms a...
Visual programming approaches are limited in their usefulness if they do not include a profile of their users that defines exactly who is attempting to solve what kind of problems...
: This paper describes the development of a model for the reflective treatment of both application and environmentally sourced exceptions. We show how a variety of exception models...
Shared memory in a parallel computer provides prowith the valuable abstraction of a shared address space--through which any part of a computation can access any datum. Although un...
