In this paper, we propose the China-US international data placement laboratory (iDPL) based on an inter-continental testbed for data placement research. iDPL is able to support various data placement research due to its scalability and flexibility in deploying the experiments in the real network environment. The core design of iDPL leverages reliable workflow management and lightweight I/O protocol...
As multi-core/many-core becomes the trend of processor architecture, conflict in shared cache has become more and more serious that restricts performance improvement of parallel program. Recent research has employed page coloring mechanism to realizing cache partitioning on real system for the purpose of decline shared cache conflict. However, page coloring-based cache partitioning has some side-effects,...
Nowadays, as the research of climate model developing to simulate the interactions between multiple physical procedures and demand high resolution results, the complexity of the climate model has increased dramatically. The traditional tight-coupling approach applied in model design has expressed tremendous burden on the code maintenance and update due to the complicated relationships between function...
Data integrity is critical for many applications. With huge amount of data shared with the cloud computing platform, i.e. Amazon S3, GFS, Apache Hadoop etc, the risk of damage is increasing at the same time. Equivocation is a powerful tool that malicious nodes can use to poison the states of honest nodes and escape punishment. Accountability which makes the system actions verifiable has become the...
Service-oriented system development is becoming a prominent software development paradigm. A lot of work has been focused on semantic Web and service integration. However, less work has been invested in how to support reconfiguration of the service oriented systems when they evolve dynamically. This paper applies architecture centric system design approach to design of the e-business systems and combines...
The key to develop maintainable and extensible e-business applications is adequate engineering method. For e-business engineering, no full-blown method currently exists. The development of e-business applications lacks high level software engineering abstractions. This paper presents a component oriented development approach to e-business applications that is strongly architecture-centric. The whole...
I/O operation within transactions is one of the challenges for hardware transactional memory. This paper analyses the problem of I/O operations within transactions, and proposes a hardware transactional memory system architecture based on multi-core processor and current cache coherent mechanisms. The system supports execution of transactions by adding transactional buffer and related hardware and...
