This paper analyzes the advantages and disadvantages of the traditional HDFS cluster architecture. An application framework designed for the small and medium-sized HDFS clusters is proposed in this paper to make up for incomplete HDFS application architecture, difficulties on deploying, inefficiency on I/O processing of small files. In addition, a caching mechanism is added to optimize the operation...
This paper analysis the current situation of instant messaging (IM) server and introduces network's load balancing which can satisfied the situation of high-capacity and concurrency. Then it summarizes some useful technologies applied in server-side, such as completion port programming, EPOLL, thread-pool and P2P, and further brings forward some prospects.
Graphics processing unit (GPU) has evolved into a general-purpose computing platform. Inspired by the GPU technology advantage, this paper concerns the design and performance evaluation of practical GPU-accelerated server architecture for Video-on-Demand (VoD) services with network coding. Following the proposal of an optimized network coding algorithm based on parallel threads on GPU, a GPU-Accelerated...
