Three such issues are (i) the problem of mapping the simulation onto the architecture, (ii) the possibilities for performing redundant computation in order to reduce com-munication, and (iii) the avoidance of deadlock due to distributed contention for message-buffer space.

Performance Issues for Domain-Oriented Time-Driven Distributed Simulations* David M. Nicof The College of William and Mary and Institute for Computer Applications in Science and Engineering Abstract It has long been recognized that simulations form an interesting and important clase of com- putations that may benefit from distributed or parallel processing.

Based on the proposed scheme, a simulation environment, namely distributed system simulator (DSS), was constructed for the evaluation of distributed application performance. DSS enables the exploitation of various types of distributed applications, including user-defined ones, as well as of the network by: Parallel and distributed simulation is a powerful tool for developing complex agent-based simulation.

Complex simulations require parallel and distributed high performance. performance issues late in the design cycle - after the simu-lation model is complete - therefore addressing changes can be rather time-consuming and costly.

An approach for the formal model-based performance eval-uation of DRE systems is demonstrated in Ptolemy II [16], that addresses some of these issues. Ptolemy II is a general. In this context, one of the most mature tools is the IEEE —Standard for M&S High Level Architecture (HLA). However, building and maintaining distributed simulations components, based on the IEEE standard, is still a challenging and costly by: 7.

In this type of simulations, the main contributions of our work are: a) we showed that distributed time-driven simulations do not always improve the performance when using synchronous communication strategies, b) we show asynchronous communications strategies are more efficient.

INTRODUCTION The analysis and design of modern distributed systems require powerful and flexible methods, tools and techniques, which are also based on bottom-up approaches and incorporate the use of simulation to support the typical phases of a software.

The text is organized in five sections. Section 1 describes the need for distributed simulation; it gives a quick survey of the system simulation problem, the sequential simulation algorithm and its shortcomings. The scope of the paper and a history of distributed simulation are also included in.

Modeling examples and a case study for a distributed database banking system are also presented. Introduction The outburst in network technology gave rise to different types of applications operating in a network environment.

In the Simulation Interoperability Workshop, Andreas Tolk started the discussion in his paper Avoiding another Green Elephant – A.

A discrete-event simulation (DES) models the operation of a system as a sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. Between consecutive events, no change in the system is assumed to occur; thus the simulation time can directly jump to the occurrence time of the next event, which is called next-event time.

The objective of this thesis is to discuss the creation of an environment that can simulate the behavior of the Agent based Distributed File System (ADFS) developed at the Milan Polytechnic and compare its performances with NFS, currently one of the most widespread file system available on the : Michele Domenico Todino.

The discussion of the process and pragmatics of object-oriented analysis and design has been greatly expanded. The process is only discussed in general terms, however, and readers must study the applications in Section 3 before appreciating the methodology. Debugging performance issues across distributed systems is a difficult task, and debugging data-driven performance issues is an even bigger challenge due to the anomalies that can be buried under millions of requests.

Sometimes, it’s like finding a needle in haystack. This proposal concerns the design and implementation of a distributed, scalable event simulation framework for use in K education. The system incorporates several components from recent research in High Performance Computing (HPC) and distributed Simulation.

This paper develops performance models that quantify the impact of these partitioning and provisioning decisions on overall distributed system performance and.

Performance models offer a convenient tool to assess design alternatives and predict the execution time of distributed simulation (DS) systems at design time, before system implementation.

Currently, perfor-mance models are to be manually developed and the related extra effort often becomes the limiting factor for their cost- and time-effective.

Migration from Central to Distributed Simulations • Benefits of decomposing the model –Modularity –can easily replace one component with another –No specific software requirements –Proprietary models can be integrated in a simulation and remain protected • Issues –Modularity adds some overhead that slightly increases execution time.

practical tool for analysis, distributed simulations can be used to reduce run time. But partly because of the expertise needed to run distributed simulations (DS) e¢ ciently, it has not yet enjoyed wide-spread use [11, 31].

This work develops a framework for predicting distributed simulation run-time performance before the simulation is run. Many systems are naturally Discrete Event Systems (DES) (e.g., Internet) → all.

This book is the bible for the software engineers. It' clearly changes the thinking perspective of every software engineer. Even though it is a "must read"book for developers who are willing to implement the domain driven design in their application, but in my opinion, others can also hugely benefitted from this book/5.

Data distribution management (DDM) is a High Level Architecture/Run-time Infrastructure (HLA/RTI) service that manages the distribution of state updates and interaction information in large-scale distributed simulations.

The key to efficient DDM is to limit and control the volume of data exchanged during the simulation, to relay data to only those hosts Cited by: 1.

some of the store procedures take more that an hour to completed.Investigating the dynamics and function of large-scale spiking neuronal networks with realistic numbers of synapses is made possible today by state-of-the-art simulation code that scales to the largest contemporary supercomputers.

However, simulations that involve electrical interactions, also called gap junctions, besides chemical synapses scale only poorly due to a .The simulation of such systems with traditional time-driven molecular dynamics is highly inefficient. Instead, it is straight-forward to consider the interactions as instanteneous events and solve the problem with an event-driven algorithm.
