Load sharing in distributed systems improves systems performance. Research in the field has been focused on steady state performance for load sharing algorithms. However, transient characteristics of such algorithms may be important in a distributed system in which workload for some node is changing. Simulation is the only means to analyze such characteristics. This paper presents a simulation-based analysis of the transient characteristics of four load sharing algorithms ; forward probing, reverse probing, symmetric probing, and multi-threshold symmetric probing algorithms. Discrete event system models for execution of the algorithms in a distributed system has been developed in a SIMSCRIOT II.5 environment. Simulation results indicate that the MSYM algorithm shows the shortest response time in the transient period.

Load distributing algorithm distributed the processor workload among the processors in the distributed system through process migration or process placement. Since several choices exist for effective process migration or process placement, we are faced with a variety of load distributing algorithm. In this paper, we propose a new load distributing algorithm(SOTC : sender oriented threshold control). Using simulation result, We show that the proposed algorithm has a better performance than random probe load distributing algorithm.

Recent years, computing environment has changed from central computing to distributed computing and needs a new technology for constructing effective and low cost servers. If a server operate appropriately on Multiple user requests, sever needs a multitasking or multithreading capability. So, every server uses Window95/NT , Linux, or Unix as operating system to provide such capability but such an operating system needs a high quality hardware. If someone needs server with low cost and low quality hardware, it is very difficult and tedious thing. In this paper, we proposed PC_XINU as a solution for constructing low cost server. In order to use PC_XINU, We introduced new function for remote execution and remote execution management and implement them.

In this paper, we propose a new load sharing algorithm. Proposed algoritm classified a threshold value of the previous algorithm into 4 kinds of threshold values according to the usage of the threshold value in the load sharing algorithm. Each threshold value can be determined easily by local processor using local informationsm, We show through simulations that proposed algorithm has better performance than the previous algorithm on the variance of the system workload and job transmission "time".

Many distributed and parallel applications can make good use of broadcast communication. A new, simple protocol for atomic broadcast is presented. This prorocol guarantees unique ordering of delevered message, i.e. the order of messages is the same at each of the recepient. In addition this protocol tolerates lost,(i.e. due to the transmission error and buffer full error) duplication, and delay of massages.

Recent Years, computing environment has changed from central to distributed computing and needs a new techonology for contructing effective and low cost server system. Server system needs multitasking and multithreading capability, but current system software need some computing power and many hardware constraints. So someone who needs server system with low cost low hardware constraints, it is very difficult and tedious thing to implement server system for a particular task. In the previous paper, we intorduced PC_XINU as a solution for constructing low cost server and implement communication capability for remote execution. In this paper, previously implemented function is extended with SIM(Server-based Information Manager). Using SIM, new processing uint is easily added, deleted, and modified. Moreover SIM provide load balancing and manage all processing information accross distributed systems.

Recently, the design and implemenation of a logic programming system capable of handing very large knowledge bases will be present. The loose coupling is an act without resursion. This paper introduces the purpose of loose coupling system with recursion. This system is implemented by adding a sub-process SELECTOR and particular two system calls. This can be used to avoid high cost in consructing a new large full integration system and coupling system of recursion problem.
