Bounded fairness is a stronger notion than ordinary eventuality-based fairness, one that guarantees occurrence of an event within a fixed number of occurrences of another event. We formalize bounded fairness by introducing a new family of temporal modal operators. The resultant logic is equivalent to temporal logic with the until modality, but more succinct. This logic can be used...
We study the computational, communication, and scalability characteristics of a computational fluid dynamics application, which solves the time-accurate flow field of a jet using the compressible Navier-Stokes equations, on a variety of parallel architectural platforms. The platforms chosen for this study are a cluster of workstations (the LACE experimental testbed at NASA Lewis), a shared-memory...
Issues related ro cumpiling for shared memory multiprocessors with multilevel memory hierarchies are discussed. In particular, a method using simple and regular sections for parallelizing nested iterative loops with constant dependence distances is described.
