Research on the Realization of Travel Recommendations for Different Users Through Deep Learning Under Global Information Management

This article is mainly to study the realization of travel recommendations for different users through deep learning under global information management. The personalized travel route recommendation is realized by establishing personalized travel dynamic interest (PTDR) algorithm and distributed lock manager (DLM) model. It is hoped that this model can provide more complete data information of tourist destinations on the basis of the past, and can also meet the needs of users. The innovation of this article is to compare and analyze with a large number of baseline algorithms, highlighting the superiority of this model in personalized travel recommendation. In addition, the model incorporates the topic factor features, geographic factor features, and user preference features to make the data more in line with user needs and improve the efficiency and applicability of the model. It is hoped that the plan proposed in this article can help users make choices of tourist destinations more conveniently.

The Construction of Heterogeneous Platform of Unified Service System Based on Cloud Computing

The primary function of intelligent grid information platform is to realize the integration and the optimization of large-scale heterogeneous information and resources, and to provide the data center of resource intensive configuration for smart grid. The platform can set all the business systems together, assign tasks reasonably, and have high concurrent access, fault transfer, fault-tolerant mechanism, buffering mechanism and other functions with distributed lock Manager. It is a unified information platform to meet the modern smart grid.

Performance analysis of three implementation strategies for distributed lock management

A distributed lock manager (DLM) provides distributed applications with a convenient means of synchronising their accesses to shared resources. The authors present a performance study of three different implementation strategies for a DLM considering both the layout of the lock database (centralised or distributed) and the strategy used to assign lock masters (static or dynamic). For each implementation strategy, accurate analytical models of communication cost, resource utilisation and lock request response time are developed. The models highlight bottlenecks in the system and show clearly for what mixes of incoming lock request types it is best to use static or dynamic lock master positioning. The analytical formulae are validated against a detailed event-driven simulation which uses realistic hardware parameters. This validation reveals a good agreement between analytical and simulation results, particularly with respect to communication cost, node and CPU utilisation, system capacity and the response time trend.

VAXcluster

A VAXcluster is a highly available and extensible configuration of VAX computers that operate as a single system. To achieve performance in a multicomputer environment, a new communications architecture, communications hardware, and distributed software were jointly designed. The software is a distributed version of the VAX/VMS operating system that uses a distributed lock manager to synchronize access to shared resources. The communications hardware includes a 70 megabit per second message-oriented interconnect and an interconnect port that performs communications tasks traditionally handled by software. Performance measurements show this structure to be highly efficient, for example, capable of sending and receiving 3000 messages per second on a VAX-11/780.
