Efficiency of Dynamic Task Assignment in Multi-User Environments
- …Task farming is an important paradigm for parallel programming in multi-user environments. This paper proves two theorems about lower bounds for the efficiency of task farming programs in multi-user environments, using a generalization of the conventional definition of efficiency and Markov processe…

Efficiency of Parallel Programs in Multi-Tasking Environments
- …The conventional definition of efficiency of a parallel program is based on the assumption that nodes are homogeneous and exclusively available for the tasks of the program. In this paper we present a more general definition of efficiency, omitting the assumptions of homogeneity and exclusivity. Thi…

External Sorting for Databases in Distributed Heterogeneous Systems
- …A common approach to external parallel sorting in parallel database query processing is to split the data of initial runs into partitions. These partitions are assigned statically to the processes of the merge phase to produce a globally sorted result. This strategy may lead to low performance if so…

Supporting Application Integrated Load Distribution for Message Passing Programs
- …This paper emphasizes an aspect which is often neglected by programming environments but which is essential for an efficient execution: the support of load distribution.…

The ALDY Load Distribution System
- …This report describes ALDY (Adaptive Load Distribution SYstem). ALDY is a combination of system integrated and application integrated load distribution. It can be used either directly by a parallel program or by the runtime system of a parallel programming environment. The flexible object model and …

Parallel Randomized Algorithms in Heterogeneous Environments
- …This paper investigates the behavior of parallel randomized algorithms in systems with dynamically changing loads. A theoretical analysis and some simulation results are presented. The sequential run time distributions considered are the exponential distribution, uniform distributions and twofold un…

Heterogeneous Partitioning in a Workstation Network
- …In this paper, we present several heterogeneous partitioning algorithms for parallel numerical applications. The goal is to adapt the partitioning to dynamic and unpredictable load changes on the nodes. The methods are based on existing homogeneous algorithms like orthogonal recursive bisection, par…

Using the ALDY Load Distribution System for PVM Applications
- …. Load distribution is an important topic for parallel applications in distributed systems. PVM supports programming of parallel applications on distributed systems. But it does not provide load distribution among processes of a parallel program. In this paper the adaptive load distribution system A…

Implementing Dynamic Load Distribution Strategies with Orbix
- …This paper proposes and evaluates various dynamic load distribution strategies for CORBA applications. A general application model for CORBA applications based on the Exporter /Importer/Trader model is introduced. For this model, techniques for the integration of load distribution strategies are sho…

"Anwendungsbezogene Lastverteilung" ALV'98
- …This paper studies load balancing issues for classes of problems with certain bisection properties. A class of problems has ff-bisectors if every problem in the class can be subdivided into two subproblems whose weight is not smaller than an ff-fraction of the original problem. It is shown that the …
