component technologies such as CORBA, COM, and J2EE. They do not work when function invocation spans processes and processors in the multithreaded and distributed applications built upon. The existing CPU resource characterization techniques perform well for the applications running as individual processes, or distributed applications involving simple interaction between two-party systems, such as traditional client/server or database systems. It is very easy to handle, because it is based on menus,īuttons and other controls which facilitate its use by non experts Read more Integrates both designing and simulation tasks. We have also developed a graphical interface which There is no need for any control process or global variables. All we have to do is create the objects, pass them their parameters, and put them to work. There are also classes for different types of queues, server and aleatory variable generators. We have created a library of classes for parallel simulation such as sources, stations and sinks, each one derived from a processing thread class. We have used C++ to implement our simulation based on queue system.

result, our parallel simulator now requires practically the same amount of memory as a We have put much emphasis on memory management and, as a. In order to do this, we have used the widely accepted Chandy-Misra paradigm, , which has shown to be very useful for The use of multiprocessor computers can speed up the simulation process but we need to maintain the precedence order between processes. Parallel processing is the key for time critical simulations. Parts of this work are supported by SION grant no.

As a case example, we discuss some issues on how to build a GIS on top of Monet amongst others how Monet can handle the very large data volumes involved. In this paper, we give the goals and motivation of Monet, and outline its architectural features, including its use of the Decomposed Storage Model (DSM), emphasis on bulk operations, use of main virtual-memory and server customization. Monet is a type- and algebra-extensible database system and employs shared memory parallelism. in a project where it is used in a high-end GIS application. It has already achieved considerable success in supporting a Data Mining application, and work is well under way. It is designed to get maximum database performance out of today's workstations and multiprocessor systems. Monet is a customizable database system developed at CWI and University of Amsterdam, intended to be used as the database backend for widely varying application domains. Transactional middleware products typically provide an abstraction called a container that helps TP application developers handle the complexities of transaction management and low-level operating system functions such as multithreading, communications, and security.

Transactional middleware products provide APIs, development tools, system management tools, and integration with popular database systems and front-end programs.

Its application code is structured to solve the transaction composability problem using whatever mechanisms are available from the underlying middleware or platform.

The request controller brackets the transaction that executes the request. It decodes the request message, determines the location of the transaction program to be called, and makes the call. The main goal of the request controller is routing.

It needs a suitably secure connection to the request controller. The front-end program is responsible for gathering input for the transaction request and the name of the transaction to be executed. This architecture is aligned with service-oriented architecture, by mapping services to transaction servers, and with object-oriented design, by mapping business objects to transaction servers. This activity usually is distributed across components of a multitier architecture. The processing of simple requests involves receiving a request, routing it to the appropriate application program, and then executing it. It is a server that appears to execute an infinite loop whose body is an ACID (atomicity, consistency, isolation, durability) transaction.

A transaction processing (TP) application is a serial processor of requests.
