Large complex system simulation in various fields of science and engineering requires tremendous computational resources;however sequential execution algorithms badly limited its performance. So recently there has been a great deal of interest in parallel and distributedsimulation, which runs on multiple processors to accelerate simulation. This paper begins with introduction of synchronization mechanisms. The emphasis of this paper is to provide and describe the implementation of the flexible cycle algorithm. This improved algorithm solves some fatal problems of conservative or optimistic algorithms, resulting in the best of both methods. Finally we also analyze how to compute the performance parameter M of this algorithm in detail.
The paper deals with simulation and analysis tools of control system with distributed inputs and outputs based on TCP/IP and UDP/IP protocols. These protocols are not strictly prepared for industrial control applicati...

This paper presents wrapping techniques that we have developed in order to integrate applications into the scientific workflow management system TENT. These techniques take into account the varying degrees of controllability found for each application and utilize various kinds of communication mechanisms between application and the associated wrapper. We also give an outline of the principles of component technology employed in the CORBA based TENT environment. In addition, the means by which applications can be connected through their associated wrappers and TENT components to form distributed workflows are presented. It is demonstrated how TENT provides the user with a homogeneous perspective on scientific workflows running in a distributed environment and how he is enabled to efficiently configure and control these workflows by means of the TENT component model.
