In this paper, a new parallel processing system for commercial applications, so called SPAX, is described. SPAX cost-effectively overcomes the SMP limitation by providing scalability of the parallel processing system and application portability of the SMP. We also describe a new system network, so called XcentNet, which interconnects hundreds of multiprocessor PC boards in SPAX. It is a hierarc...

The emergence of low latency, high throughput routers means that network locality issues no longer dominate the performance of parallel algorithms. One of the key performance issues is now the even distribution of work across the machine, as the problem size and number of processors increase. This paper describes the implementation of a highly scalable shared queue, supporting the concurrent in...

Onion routing protocols achieve low-latency anonymous communication on public networks. Up to date, many onion routing protocols have been proposed, such as Tor network, in order to implement the anonymous network connection in the public networks. Although the previous schemes’ multi-pass cryptographic circuit construction appears satisfactory, their circuit construction protocols have some dr...

It is noticed that traditional loss based algorithms are not moving data very well in today's Internet. To get bottleneck bandwidth fully utilized, these will keep increasing the congestion window and maintain a standing queue of packets routers, which cause large end to latency. Such long latency quite annoying ever growing delay sensitive applications. Recently, much effort has been devoted b...

True broadband access for high-speed train passengers has become a new trend in the world. To support the newly emerged mobile applications effectively, the mobile network’s handover latency and packet losses during handover need to be as small as possible. To address this issue, a fast handover scheme based on multiple mobile router cooperation for mobile networks is proposed in this paper. It...

Network overlay construction has found many applications in today’s Internet, such as P2P networks [1][2], end-host multicast [3][4], and network security [5]. Many researchers have proposed solutions to building an overlay network among a given group of end-hosts. The usual overlay construction assumes two-way network communication— each host can initiate connections to and accept requests fro...

Network on Chip (NoC) has emerged as a promising on chip communication infrastructure. Three Dimensional Integrate Circuit (3D IC) provides small interconnection length between layers and the interconnect scalability in the third dimension, which can further improve the performance of NoC. Therefore, in this paper, a hierarchical cluster-based interconnect architecture is merged with the 3D IC....

The Low Latency Fault Tolerance (LLFT) system provides fault tolerance for distributed applications within a local-area network, using a leader-follower replication strategy. LLFT provides application-transparent replication, with strong replica consistency, for applications that involve multiple interacting processes or threads. Its novel system model enables LLFT to maintain a single consiste...

Recent years have seen remarkable progress in semantic segmentation. Yet, it remains a challenging task to apply segmentation techniques to video-based applications. Specifically, the high throughput of video streams, the sheer cost of running fully convolutional networks, together with the low-latency requirements in many real-world applications, e.g. autonomous driving, present a significant ...

In this paper we present a modiication of the CORDIC algorithm which reduces the number of iterations almost to half by merging two successive iterations of the basic algorithm. The two coeecients per iteration are obtained with only a small increase in the cycle time by estimating one of the coeecients. A correcting iteration method is used to correct the possible errors produced by the estima...
