To improve the resource utilization jobs running in the production clusters shares the available resources by assigning with different priorities. Preemption is one of the common technique used by the schedulers in Hadoop systems to prevent the delay in the job completion, also to ensure that the available resource is effectively shared among the running jobs. In addition, this prevents large jobs,...
Reliability prediction methods for a computer measure and control system with apparatus counting method and similar product method are presented. MTBF is predicted to find weak parts in system design. The prediction will provide basis for reliability allocation.
Heterogeneity in resources pervades all modern computing platforms. How do the effects of heterogeneity depend on which resources differ among computers in a platform? Some answers are derived within a formal framework, by comparing heterogeneity in computing power (node-heterogeneity) with heterogeneity in communication speed (link-heterogeneity). The former genre of heterogeneity seems much easier...
The sensitivity assessment method has been invented to increase he accuracy and easiness in reliability allocation based on the military standards and extant experiences. In usual allocation method complexity, technology, environmental conditions and life time are defined as influential parameters for a system reliability calculating. So, with the assessment of these factors for each product, quantity...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
It is necessary to analyze the anti-terrorism performance of Taiwanpsilas security system after September 11, 2001 attacks. We use three stage data envelopment analysis model that Fried et al. (2002) developed, getting intelligence performance of the Investigation Bureau of the Ministry of Justice, to discuss the ability of anti-terrorism in Taiwanpsilas national security system. Putting 10 outputs,...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
