Fire Phoenix Cluster Operating System Kernel and its Evaluation

Fire Phoenix cluster operating system kernel (Phoenix kernel) is a minimum set of cluster core junctions with scalability and fault-tolerance support. In this paper, we define components of cluster operating system kernel, and introduce its internal mechanism for scalability and fault-tolerance support. Based on Phoenix kernel, user environments can be easily constructed according to users' needs. In addition, we evaluate Phoenix kernel from four different perspectives, such as fault-tolerance, scalability, performance impact on scientific computing, and easiness of constructing user environment. Our design has been proved in the practices of Dawning 4000A super server, which is the biggest cluster system for scientific computing in China
