    Please note that this problem is different from the standard graph partitioning problem since we are dealing with a DAG rather than an undirected graph. "Graph partitioning models for parallel computing" by Hendrickson and Kolda has pointed to the aforesaid problem but does not provide any solution to it. Key Topics: The book covers in detail the main three models of computation used to design parallel algorithms (namely combinational circuits, shared memory machines, and interconnection networks). The algorithms are grouped by method of design (prefix computation, divide and conquer, and pointer based : $

Then we present the previous work on the utilization of the parallel computers including task partitioning algorithms and task mapping algorithms. Classes of Parallel Computers Parallel computers can be roughly classified according to th e level at which the hard-ware supports parallelism.

Get this from a library. Partitioning and packing mathematical simulation models for calculation on parallel computers. [Dale J Arpasi; Edward J Milner; Lewis Research Center.]. Finding an optimal data partitioning for a data-parallel program is challenging.

Solutions from parallel database (DB) communities are not directly applicable due to the differences in data and programming models.

We list some of the challenges below. 2Cited by: Appropriate machine models and partitioning approaches for heterogeneous architectures are largely an untouched area, although one step in this direction has been taken by Teresco et al.

Most of the work on parallel partitioning has been done in the context of dynamic load by: CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Calculations can naturally be described as graphs in which vertices represent computation and edges reflect data dependencies.

By partitioning the vertices of a graph, the calculation can be divided among processors of a parallel computer. However, the standard methodology for graph partitioning. Level-Set-Based Partitioning and Packing Optimization of a Printable Model we present a systematic study on the partitioning and packing of 3D models under the multi-phase level set framework.

Such heuristics are useful for decomposing large, constrained, optimization problems into forms that are amenable to parallel processing.

The heuristics presented can be easily implemented using publicly available graph partitioning algorithms.

In this paper we present new parallel approach for the dynamic partitioning of particle-mesh computational systems. The approach uses a framework, the “in-element” particle tracking method, based on the assumption that particle trajectories are computed by problemdata localized to individual by: 3.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Logic simulation of a complex processor model in VLSI design is very time consuming.

One possibility to increase the simulation speed is to partition the processor model and assign the resulting parts to simulator instances that cooperate over a loosely-coupled system.

The book presents two approaches to automatic partitioning and scheduling so that the same parallel program can be made to execute efficiently on widely different multiprocessors.
