Although medical technologies developed in the twenty-first century have successfully increased man's life span, the pressure of modern life has consequently brought many modern civilization diseases and chronic illness. When all these problems are tackled by hospitals, they will consume considerable amount of medical resources. Alternatively, providing(More)
Due to the high availability of the Internet, many large crossorganization collaboration projects, such as SourceForge, grid systems etc., have emerged. One of the fundamental requirements of these collaboration efforts is a storage system to store and exchange data. This storage system must be highly scalable and can efficiently aggregate the storage(More)
In distributed shared memory (DSM) systems, it is the common need to access data in remote nodes. Thus, it induces to remote access performance latencies, which is the major factor of overhead for DSM systems. Prefetching strategies can improve these phenomena by reducing latencies, but it adds workload to home nodes. It is proposed in this paper a method(More)
Over the past decade, the development of Internet technology has led to more awareness on the powerfulness of Peer-to-Peer (P2P) overlay network. How to efficiently establish or maintain overlay networks in large-scale environments always are important issues. Besides, the ways of improving routing efficiency also attract much attention. This study proposes(More)
Distributed Shared Memory systems provide the abstraction of a shared address space among computing hosts interconnected via a private network, in a convenient and easy way to achieve high performance. However, there are several drawbacks to these systems, such as communication overhead, network latency, false sharing, coherence and page faults. By(More)
Network function virtualization (NFV) has drawn much attention in recent years, where some network functions that used to be deployed on specific hardware have become virtualized instances on general servers to achieve more scalability and flexibility. In a data center, service function chaining (SFC) makes a workflow traverse different network functions in(More)
In distributed shared memory (DSM) systems, one of the major overheads is page fault, because it induces remote memory access latencies. Prefetching strategy permits home nodes sending data to remote nodes in advance, in order to reduce page faults and latencies, as also to improve overall performance; however, it causes accumulated waiting phenomenon,(More)
High speed networks and rapidly improving microprocessor performance make the network of workstations an extremely important tool for parallel computing in order to speedup the execution of scientific applications. Shared memory is an attractive programming model for designing parallel and distributed applications, where the programmer can focus on(More)
