Apache ZooKeeper is a distributed data storage that is highly concurrent and asynchronous due to network communication, testing such a system is very challenging. Our solution using the tool "Modbat" generates test cases for concurrent client sessions, and processes results from synchronous and asynchronous callbacks. We use an embedded model checker to compute the test oracle for non-deterministic...
This paper shows how the extended compact genetic algorithm can be scaled using data-intensive computing techniques such as MapReduce. Two different frameworks (Hadoop and MongoDB) are used to deploy MapReduce implementations of the compact and extended compact genetic algorithms. Results show that both are good choices to deal with large-scale problems as they can scale with the number of commodity...
Network operation complexity model is proposed in this paper. This model includes nested system model, operation process model and quantitative indicator model. Then, a normalization treatment method of indicator data is put forward. After constructing a network system in the laboratory, we apply the model to the operation process of network and obtain complexity indicator value through measuring...
