Evaluation system of extendable program competition based on service

Abstract

The invention relates to an evaluation system of an extendable program competition based on services. The evaluation system consists of a Web server, an application server, an evaluation scheduling server, a data server, a backup server and an evaluation server. The application server and the evaluation scheduling server are connected with the Web server by network respectively; the evaluation scheduling server is connected with the data server, the backup server and the evaluation server in a communication manner respectively; and the application server is connected with the data server and the backup server in a communication manner respectively. By adopting the system, the structure is easy to extend, and an on-line evaluation system has a large throughput, fast response speed and strong openness. The data safety is ensured by the backup server and an incremental backup mode. Meanwhile, the dynamic evaluation dispatch strategy has a large application range and strong flexibility, so that the system is suitable for program evaluation in the program competition and can be applied in a computer teaching experiment.

Description

technical field [0001] The invention relates to a service-based program competition and an online evaluation system in the field of computer teaching experiments, in particular to a scalable distributed system for judging whether the program is running correctly or not in real time, and whether the efficiency is high or low. Background technique [0002] With the development of the ACM International Collegiate Programming Contest and similar programming competitions, an online evaluation system that can receive source code submitted by users online, judge whether the program is right or wrong, and notify users of the results in real time has become popular. This kind of system plays a very important role in the pre-competition training and organizing competitions of programming competitions, and the online evaluation system can also provide students with a practice platform in the teaching of programming design, increase students' practice opportunities, and improve the lev...

Problems solved by technology

However, this mode forms an isolated and closed training and competition environment, and it is difficult to realize resource sharing and information fusion between various competition systems. The low usage rate after competitions causes waste of the system, so this mode is not flexible enough and open enough , its cost is too high for some small and medium schools

Moreover, the indiscriminate use of application services and evaluation scheduling services may easily lead to the real-time evaluation of the system under competition conditions.
