Present article highlights the researches provided during the development of holographic memory system based on application of computational methods to encode binary data pages as amplitude computer generated Fourier holograms (CGFH). Using electro-optical micro-display and projection optics CGFH can be recorded onto photosensitive medium. The type of display that is used in data recorder determines the specificities of optical scheme architecture with its own limitations and advantages. There are three projection schemes of binary data recorder discussed in the paper. A linear scheme based on transparency-type liquid crystal spatial light modulator (LC SLM), a scheme based on reflection-type liquid crystal on silicon spatial light modulator (LCoS SLM) which uses a beamsplitting cube, and the most compact and simple scheme based on self-emitting OLED-display. The results of experimental implementation of all the three projection schemes for CGFH of binary data pages record onto the holographic carrier and consequent optical reconstruction and analysis of the encoded data are presented. 相似文献

A new architecture for large-scale information systems is presented. The original aspects of the architecture are mainly: (1) the time-triggered, message-triggered object (TMO) structuring of the middleware and the application software of distributed real-time information systems; and (2) the dynamic configuration management subsystem (DCMS), based on the supervisor-based network surveillance (SNS) scheme. The positive impacts of this TMO structuring on maintainability and service interruption bounds are first discussed, with distributed replicated information service systems and other systems as examples. The main discussion is on the DCMS architecture. As a component of the DCMS, the network surveillance (NS) subsystem enables fast learning, by each interested fault-free node in the system, of the faults or repair completion events occurring in other parts of the system. Currently, concrete real-time NS schemes that are effective in distributed systems based on point-to-point network architectures are scarce. The SNS scheme presented in this paper is a semi-centralized real-time NS scheme which is effective in a variety of point-to-point networks. This scheme is highly scalable. An efficient implementation model for the SNS scheme is presented that can be easily adapted to various commercial operating system kernels. This paper also presents a formal analysis of the SNS scheme, on the basis of the implementation model, to obtain its strongly competitive tight bounds on the fault detection latency. Finally, some DCMS implementation issues are discussed that remain to be addressed in future research 相似文献

Parallel joins have been widely studied during the past decade and a number of efficient algorithms were presented. While it is known that the performance of these algorithms may suffer greatly in the presence of skewed input data, the work on load balancing schemes for parallel join has been limited. The main contribution of this paper is the development and analysis of a new distributed data structure and an effective load balancing scheme for parallel main memory hash join on NUMA architecture. Multiprocessors based on this architecture are scalable in both size of main memory and number of processors, and provide very high memory bandwidth. The load balancing scheme is based on random probing to avoid the hot spot problems caused by probing sequentially. We have modeled this load balancing scheme both analytically and experimentally. The experiments were run on a BBN TC2000 multiprocessor system 相似文献
