Abstract-After analyzing current status of automatic marking methods for programming questions, a novel script-based approach was proposed for designing marking rule. This paper studied the design and implementation of an automatic marking system. The system marks console programs written in a plurality of programming languages. It is composed of two parts, a dynamic-test module and a static-test module based on the script-based approach. Code-marking rules are written in script files. In the dynamic-test module, the programs of the students are compiled, executed and marked with test cases. In the static-test module, the script files are analyzed and executed with both the programs and the outputs of the dynamic-test module. Suggests would be given to improve the quality of those console programs. Experiments showed that the static-test module enhances functions of the marking system.

Abstract. We present a scalable method to implement the construction of neighbor list in molecular dynamic simulations on multi-core platforms. Our methodology is based on the OpenMP programming model. Our method doesn't divide the whole of simulation region into cells. Each thread builds and maintains a few sliding cells for a neighbor list constructions. It reduces memory requirements and code complexity. Compared with some other methods applied in the neighbor list construction, the results of our experiments indicate that it is a scalable and efficient method.
