In the multi-dimensional numerical simulation of certain multi-phase fluid flow processes, many phenomena are sufficiently localized and transient that self-adaptive local grid refinement techniques are necessary to resolve the local physical behaviour. For large-scale simulation problems, efficienc

β¦ Synopsis
The solution of partial differential equations on a parallel computer is usually done by a data parallel approach. The grid is partitioned and mapped onto the processors. However, partitioning of unstructured meshes and adaptively refined meshes in general is an N P -hard problem and heuristics are needed. In this paper a parallelisable and cheap method based on space-filling curves is analysed. Quasi-optimal estimates are derived for partitions of adaptively refined grids.

A centralized scheduler must assign tasks to servers, processing on-line a sequence of task arrivals and departures. Each task runs for an unknown length of time, but comes with a weight that measures resource utilization per unit time. The response time of a server is the sum of the weights of the
## Abstract An adaptive finite element scheme for transient problems is presented. The classic hβenrichment/coarsening is employed in conjunction with a tetrahedral finite element discretization in three dimensions. A mesh change is performed every n time steps, depending on the Courant number empl
This paper presents a new adaptive algorithm for dynamic load balancing on a shared BUS architecture. We present results obtained from simulation studies and queuing analysis, which reflect the relation between the BUS contention and the efficiency of load balancing. The proposed algorithm uses a sc
Solving initial value problems (IVPs) for ordinary differential equations (ODEs) has long been believed to be an inherently sequential procedure. But IVP solvers using the extrapolation method provide high quality solutions and offer a great potential for parallelism. In this paper, we present algor
