Comparing Atomic Broadcast Algorithms in High Latency Networks

André Schiper, Nils Richard Ekwall

Since the introduction of the concept of failure detectors, several consensus and atomic broadcast algorithms based on these detectors have been published. The performance of these algorithms is often affected by a trade-off between the number of communica ...

Fault-tolerant dynamic parallel schedules

Sebastian Gerlach

Dynamic Parallel Schedules (DPS) is a high-level framework for developing parallel applications on distributed memory computers such as clusters of PCs. DPS applications are defined by using directed acyclic flow graphs composed of user-defined operations. ...

Can a Helmholtz solver run on a cluster?

Marc Anthony David Habisreutinger, Emmanuel Leriche, Vincent Keller

Our vectorized Helmholtz solver runs at 85% efficiency on a NEC SX-5. The most time-consuming parts have been ported on SMP, NUMA, and cluster architectures. It is shown that an OpenMP version can deliver similar performance when running it on a 16 process ...

A simulator for parallel applications with dynamically varying compute node allocation

Roger Hersch, Sebastian Gerlach

Dynamically allocating computing nodes to parallel applications is a promising technique for improving the utilization of cluster resources. We introduce the concept of dynamic efficiency which expresses the resource utilization efficiency as a function of ...

Parallel network simulations with NEURON

Henry Markram

The NEURON simulation environment has been extended to support parallel network simulations. Each processor integrates the equations for its subnet over an interval equal to the minimum (interprocessor) presynaptic spike generation to postsynaptic spike de ...

Evaluating scheduling policies for fine-grain communication protocols on a cluster of SMPs

Babak Falsafi, David Wood

Distributed-memory parallel computers and networks of workstations (NOWs) both rely on efficient communication over increasingly high-speed networks. Software communication protocols are often the performance bottleneck. Several current and proposed parall ...

Fault-tolerant parallel applications with dynamic parallel schedules

Roger Hersch, Sebastian Gerlach

Commodity computer clusters are often composed of hundreds of computing nodes. These generally off-the-shelf systems are not designed for high reliability. Node failures therefore drive the MTBF of such clusters to unacceptable levels. The software framewo ...

JMSGroups

Arnas Kupsys

Nowadays, computers are the indispensable part of our life. They evolve rapidly and are more and more versatile. Computer networks made the remote corners of the world just a click away. But unavoidably, any software and hardware component is subject to fa ...

A Model for Parallel Programming over CORBA

Existing models for parallel programming over Common Object Request Broker Architecture (CORBA) do not address issues specific to parallel programming over a Network of Workstations (NOWs). This paper presents P-CORBA, a model for parallel programming over ...

Towards JMS Compliant Group Communication - a Semantic Mapping

André Schiper, Matthias Wiesmann, Stefan Pleisch, Arnas Kupsys

Group communication provides communication primitives with various semantics and their use greatly simplifies the development of highly available services. However, despite tremendous advances in research and numerous prototypes, group communication stays ...
