Workflows offer a great potential for enacting co-related jobs in an automated manner. This is especially desirable when workflows are large or there is a desire to run a workflow multiple times. Much research has been conducted in reducing the make span of running workflows and maximising the utilisation of the resources they run on, with some existing research investigates how to reduce the energy...
Network simulations mostly focus on protocol observation, development, and prediction. However, newly developed protocol will take time to become standard and be implemented on network devices. A faster way of network improvement is to optimize existing network card parameters, because they are generic and protocol-independent. In this paper, we propose mathematical models to represent network card...
Bluetooth Low Energy (BLE) is a recently developed energy-efficient short-range radio communication technology, which is currently vastly gaining popularity and which might become an enabler for implementing in practice the Internet of Things (IoT) concept. However, the complexity of the protocol and the lack of the simulation tools impedes the studies of BLE network performance. For this reason,...
We have proposed a memory sharing method of the wormhole routed network-on-chip architecture. In our method, a memory is shared between multiple physical links by using the multi-port memory. We evaluate and discuss the communication performance in the various situations. It is shown that the minimum number of memory banks required in multiport memory for 2D-torus and 2D-mesh networks is 8. Our proposed...
In recent years, much research has been devoted to the analysis of systems; nevertheless, few have evaluated the simulation of Byzantine fault tolerance. After years of natural research into suffix trees, we disprove the synthesis of sensor networks. In this work we present a solution for the understanding of reinforcement learning (SelfishRater), disconfirming that IPv7 and Byzantine fault tolerance...
Hashing is popularly adopted when it comes to a large scale of IP flows. This paper mainly focused on the lookup performance of content addressable memory aided hash table (CAHT). High throughout is available with minimized average memory access number. By rational approximation, the paper provided the lower bound on average memory access number over CAHT. When the hash is perfect hash or nearly to...
This paper shows the influence of network aspects and MPI implementation on the performance of an Ethernet based computer cluster. Following factors are considered: message size, number of nodes, node heterogeneity, network speed, switching technology and MPI implementation. The basic index of performance is throughput measured with Intel MPI Benchmark. This paper shows that there is a specific message...
Performance of a reliable storage subsystem for a centralized database system was studied by simulation. The reliable storage subsystem studied consists of three redundant disk units that are updated one at a time from a consistent database state to another consistent database state. Thus, even if a central processor and/or one disk unit fail simultaneously, at least one disk unit will contain a consistent...
