Research And Implementation Of Data Recovery And Scheduling Strategy In Computer Architecture Lab-Cloud

In the traditional teaching process of computer course, different course of computer system architecture supporting different experiments curriculum to strengthen students’ understanding of the relevant theoretical knowledge and exercise the practical abilities of students. But these experimental curriculum have a strong cross-correlation in some degree, ancillary to carry out the appropriate experiments for a variety of computer-related courses using different experiment equipment. Therefore resources waste resulted from serious redundancy in experiment hardware devices by this experimental teaching methods, in the meanwhile students had to spend a lot of effort to become familiar with the different experiments setting, resulting in a waste of students’ time and energy. With the emergence of cloud computing, resource efficient use,convenient deployment and service personalization had widespread concerned and it is becoming a successful business model increasingly popular today. Therefore, drawing on the cloud computing service concept, we design and develop computer-related curriculum remote experimental teaching system, which based on experimental hardware board “tian he yang guang VER1.3”independently developed by our school,deployed in the cloud.The computer architecture remote experiment system integrated computer-related experimental hardware devices in a resource pool for the experimental users. If the remote experiment teaching system, deployed in the cloud, want to take measure improve efficiency of resources, the experimental system hardware scheduling and management is essential. Therefore, the mainly work as in the following:1. Giving the corresponding discussion with cloud computing and remote experiment system, as well as studying the current popular related technologies in remote experiment system and cloud computing. Those were laid the theoretical basis of computer architecture lab-cloud.2. We designed and implemented a lab-cloud prototype system in B/S mode,experimental users could access lab-cloud system through a browser and do their experiment that real-time control the remote laboratory equipment to complete their experimental task on the hardware devices in the cloud.3. we designed and implemented data recovery technology in lab-cloud system.this technology can extracted and protected the relative importance of user experimentalinformation and improved system stability, as well as for the management of scheduling experiment hardware in the next work of strategy scheduling.4. As scheduling efficiency of experiment hardware in lab-cloud system was not high, we designed and implemented three system strategy according to the different number of users to access different experiments under different circumstances, and then deployed the experiment system in the LAN and run some test in it. the test resulting showed that the prototype lab-cloud without scheduling strategy by comparing the lab-cloud has been effectively improve system efficiency after adding cloud scheduling strategy.
