404 Effciency 1.2 1 0.8 0.6 0.4 such as input data transfer time makes the speed up and efficiency dropped. In this test, we reduced the data transfer time by replicating VaR database to all workers. So, the efficiency and speed up were nearly perfect. 3. The super speed up and the over efficiency. This characteristic happened because the overhead time before calling web services of client application makes the run time of client application increased. The high number of jobs made the total overhead time grower. However, the total overhead time was reduced by the increasing of number of workers. So, at the large amount of jobs such as 2000 and 3000 jobs, the run times of 2, 4, 8, 16, and 32 workers system were decreased more than the number of workers in system. CONCLUSION The demand of using super computing system in organizations has been increasing. They Kasetsart J. (Nat.

Number of workers 100 Jobs 500 Jobs 1000 Jobs 2000 Jobs 3000 Jobs need the system that has more dynamicity and flexibility in order to support the various types and large amount of demand of customers. Moreover, this system must provide an easy and familiar mechanism for customers to use the power of system. This paper proposed the design and implementation of framework used for building the computing environment that can achieve these requirements. This framework is called OpenUCI (Open Utility Computing Infrastructure) which works on Microsoft .NET platform. OpenUCI will gather resources distributed on the network, and automatically adjust and provisioning resources to users. The prototype of OpenUCI has already been implemented and evaluated with a financial engineering application named VaR calculation. The result of evaluation showed that OpenUCI can give a good performance and high utilization when the number of computers and demand of users increased The prototype version of OpenUCI has only a few modules such as resource collecting
and discovery, resource selection and broker mechanism. There are still many necessary modules that should be implemented, for example, web and grid services invoker, job queue manager and virtual computer management. The following is the list of future work. There are many possible works in the future such as integrating the executable file launcher implemented in another related project to OpenUCI system, implementing the job queue management module, implementing the web and grid services invoker module, implementing the virtual computer management service, implementing the user authentication and accounting modules, implementing the data transfer service, exploring the mechanisms for handling fault of machines and jobs and investigating a proper workload distribution scheme and study using simulation. All these works will make OpenUCI more useful in the modern computing environments. LITERATURE SITED Albaugh V. and H. Madduri. 2004.
