Program Trading has gotten more popular recent years. According to thestatistics, there was about 53.6% of daily volume in the United States, and increased to 73% in 2009. With the universal of program trading, more people have begun to research program trading. The purpose of this paper is constructing a developed platform of program trading for researching or developing. In addition to developed platform, we provide the run-time environment, and three main functions: 1. The job scheduler 2. The high scalability 3. The developed platform In this paper, we use SLURM to implement an economical computing service for program trading. SLURM is a resource management software for some large clusters. However it lacked for an easy interface to the ended users. We modify Xinetd as the external interface for SLURM, and implement the program trading development platform for researching or developing. According to the result, using our scheduler and the external interface that modify from Xinetd can be effective in controlling the server resource and increase the availability.

This thesis is aimed to study the possibility of usage of mobile devices in the sphere of automation. One automation company needed to have in hand some PDA-based tool for a remote control of the technological process. There is analysis of ability of contemporary portable devices to run a application software. According to the specified requirements there is designed and implemented the client-server system based on the VNC technology. The server is a Linux-based PC server implemented using Xinetd daemon and the Xvnc. The two standard VNC clients were made. A free software available under the GPL license was modified to implement them. One runs on Windows Mobile operating system and the other one is a Java MIDlet.
