Named Data Networking (NDN), a revolution of the IP architecture, provides an information-centric paradigm to transmit video traffic which occupies most of the Internet traffic. However, the data caching schemes exploited by the current NDN can easily result in the unfair distribution of cache space, which is not suitable for performance isolation when there are multiple network users and the cache...
In order to provide the cloud computing research community with a full-system level datacenter server emulator with programmable hardware and software, and stimulate more innovative research work, this poster and demo shows a scientific research platform, Titian2, designed and implemented at ICT of CAS. Titian2 has the ability of on-line profiling and measuring, and the scalability of connecting with...
In this paper, we proposed a hierarchical multiple intelligences architecture consisting of three intelligences: biology intelligence, space intelligence and robot intelligence. This new intelligence architecture aims to address defects of existing intelligence architecture for controlling mobile robots. The performers of the three intelligences are human, intelligent space and robot, respectively...
We seek to enable efficient large-scale parallel execution of applications in which a shared filesystem abstraction is used to couple many tasks. Such parallel scripting (many-task computing, MTC) applications suffer poor performance and utilization on large parallel computers because of the volume of filesystem I/O and a lack of appropriate optimizations in the shared filesystem. Thus, we design...
We have extended the Falkon lightweight task execution framework to make loosely coupled programming on petascale systems a practical and useful programming model. This work studies and measures the performance factors involved in applying this approach to enable the use of petascale systems by a broader user community, and with greater ease. Our work enables the execution of highly parallel computations...
