Cloud computing is attracting an increased number of researches in delivering modeling and simulation abilities as a service. Among which, simulation execution as a service (EaaS) is a hot spot. It aims at releasing users from complex running configurations and meanwhile guaranteeing the QoS requirements. Under the motivation, focusing on EaaS for parallel and distributed simulation (PADS) application,...
Cloud network system will meet the military demand on sea battlefield more effectively. Taking cloud computing as the core, the conception of sea battlefield cloud network has been presented. Combat cloud from it can strengthen the capability of collaborative combat in sea battlefield. Then, infrastructure of sea battlefield cloud network is constructed according to the tactics needs on sea battlefield...
A data reconstruction scheme for the storage code that possesses the combination property (CP) and zigzag decod-able (ZD) is proposed for distributed storage system. (n, k) CP is defined as follows: k message with each containing L bits are encoded to n ≥ k packets and then stored into n storage nodes, respectively. Any k from these n storage nodes can recover the original message. The code operates...
The cloud computing paradigm attracts increasing amount of efforts to move high performance parallel applications to run in remote data cenetres. How to balance the performance requirements of parallel applications and the datacentre utilization is essential to the move. Existing parallel scheduling mechanisms normally do not consider workload consolidation for improving server utilization. In this...
Cloud computing is of particularly population these days, it is changing the way of delivering and consuming IT resources of kinds. Private cloud computing is more appealing and acceptable than public cloud computing at this stage since there is no security issue which is intensively concerned by all serious users. But on the one hand, currently widely used open source virtualized environment managers...
Cloud computing provides various IT resources to users transparently in an easy-to-use, on-demand, cheap and pay-as-you-go manner. It frees users of burdens associated with managing computing resources and facilities, and reduces or even eliminates the capital outlays in hardware. These advantages are helpful to make simulation techniques become more accessible to users. Cloud-based computer Simulation...
The cloud computing paradigm attracts increasing amount of Modeling&Simulation (M&S) practitioners to perform their simulations in the cloud. Two issues, namely, the architecture of the Cloud-based Simulation (CSim) and the parallel simulation job scheduling in the CSim, should be addressed ï¬rst to make the CSim practical. This paper reports our recent work on the two issues. The...
The Cloud is considered to be an important platform for the execution of scientific applications such as scientific workflows. Effective plan and management are desired in complex spatial analysis and decision applications. Geospatial workflow provides a scientific solution to manage such geospatial processes; it can define geospatial processes precisely to solve particular spatial-referenced issues...
Cloud platform provides an infrastructure for resource sharing, software hosting and service delivering in a pay-per-use approach. To test the cloud-based software systems, techniques and tools are necessary to address unique quality concerns of the cloud infrastructure such as massive scalability and dynamic configuration. The tools can also be built on the cloud platform to benefit from virtualized...
