Although many graph processing systems have been proposed, graphs in the real-world are often dynamic. It is important to keep the results of graph computation up-to-date. Incremental computation is demonstrated to be an efficient solution to update calculated results. Recently, many incremental graph processing systems have been proposed to handle dynamic graphs in an asynchronous way and are able...
With the increasing requirements of large-scale animation rendering, I/O congestion has become one of the main bottlenecks to constrain the whole performance seriously. What's worse, frequent rendering data access in remote storages brings a heavy burden of storage and delay of data access. Distributed Memory caching System for Rendering (RenDMS) is proposed to alleviate I/O congestion and improve...
Exploitation of covert channels in smartphone operating systems may lead to furtive data transmission between applications with different permissions, which might threaten users' privacy. Restricting the access to shared system resources can effectively prevent the exploitation of known covert channels. However, it inevitably limits the normal usage of those resources. In this paper, we propose a...
As multi-core platforms with hundreds or even more quantities of cores are popular, system optimization issues, including lock contentions, start to puzzle programmers who work on multi-core platforms. Locks are more convenient and clear than lock-free operations (for example, transactional memory) for multi-core programmers. However, lock contention has been recognized as a typical impediment to...
This paper proposes an approach of radical-based online handwritten Chinese character recognition using support vector machine (SVM). In our system, after the input Chinese character is preprocessed, segments ,the structure feature of the character are extracted and the middle point of each segment is projected in horizontal and vertical directions to detect that which type the character's pattern...
