Schedules for Dynamic Bidirectional Simulations on Parallel Computers
… thesis extends the theoretical results of the parallel reversal schedules. First a algorithm was constructed which carries out the ``forward'' calculation and distributes checkpoints in a way, such that the reversal calculation can be started at any time. This approach provides adaptive …

Large eddy simulations of bluff-body wakes on parallel computers
… calculations have been performed on massively parallel processing computers. The governing equations are approximated by a finite-volume discretization. Several alternate interpolation schemes, including a third-order (QUICK), a fifth-order, and a seventh-order upwinding-biased scheme, have …

Frontal algorithms for equation-based chemical process flowsheeting on vector and parallel computers
… code (without indirect addressing). On parallel computers, the inner loops of the elimination phase can be multitasked by simply subdividing the frontal matrix. Flowsheeting results show that the frontal approach performs very well on the CRAY X-MP/416 architecture. However, several …

Piecewise Linear Approach for Timing Simulation of VLSI Circuits on Serial and Parallel Computers
The work presented in this thesis deals with the development of a fast and fairly accurate Computer Aided Design software for simulating very-large-scale-integrated (VLSI) circuits. The methods rely on piecewise linearized nonlinear elements in the circuits.

Symbolic analysis for parallelizing compilers
… of a program for efficient execution on parallel computers. The dependence structure of a program defines the necessary constraints of the order of execution of the program components, and provides sufficient information for the exploitation of the available parallelism. Static discovery …

A Stochastic Lagrangian Model for Non-Gaussian Fluid Turbulence and Its Application to Describe Particle Dispersion in a Channel
… direct simulations. They are ideally suited for parallel computers. The stochastic model is about 120 times faster than the DNS on a single processor on the Convex C-3. Furthermore, the stochastic models can be used at higher Reynolds numbers and in more complex situations that is possible with a …

A co-processor design to support MPI primitives in configurable multiprocessor designs
… standard for inter-processor communication in parallel computers. This standard is normally implemented in software, thus resulting in large communication latencies. A hardware implementation can reduce communication latencies significantly, thereby increasing the bandwidth. However, this …

Orderings and direct methods for coarse granular parallel solutions in equation-based flowsheeting
… it becomes important to identify a coarse parallel task granularity in algorithms that are executed on parallel computers. At the same time, such coarse granular tasks should represent a fairly uniform processor load distribution. Previously proposed methods for identifying coarse task …

Automatic Data Partitioning on Distributed Memory Multicomputers
Distributed-memory parallel computers are increasingly being used to provide high levels of performance for scientific applications. Unfortunately, such machines are not very easy to program. A number of research efforts seek to alleviate this problem by developing compilers that take over the task …

Load Balancing Regular Meshes on SMPS with MPI
Domain decomposition for regular meshes on parallel computers has traditionally been performed by attempting to exactly partition the work among the available processors (now cores). However, these strategies often do not consider the inherent system noise which can hinder MPI application …
