Synchronization In C

This paper mainly focuses on the synchronization mechanism of UPC, through a large number of program instances, so that the learners of UPC language can learn more comprehensively the usage of upc_barrier, upc_notify, upc_wait and upc_fence statements. Unified Parallel C (UPC) is a parallel programming language that supports multithreading. It is based on the C language to join the upc_barrier,upc_notify, and upc_wait statements to ...

The design and implementation of mobile terminal data synchronization in personal cloud system Beijing posts and telecommunications Feng Juling This paper proposes a new method of mobile data synchronization to achieve the consistency of data, use the way of log storage differences, and C/s structure optimistic replication method. This method effectively reduces the communication overhead and effectively solves the problem of synchronization and consistency of terminal data in mobile environment. The system design takes into account the usability, efficiency, comprehensiveness, extensibility and accessibility, ensuring the robustness of the system and the efficient use of data. The system can be divided into platform side and mobile terminal side, platform side receive each ...

Rsync (synchronize) is a remote data synchronization tool that allows you to quickly synchronize files between multiple hosts by LAN. You can also use rsync to synchronize different directories on your local hard disk. Rsync is a tool to replace RCP, and Rsync uses the so-called rsync algorithm for data synchronization, which transmits only two different parts of the file, rather than sending it all at a time, so it's very fast. You can refer to how to Rsync works A ...

Research on the construction of medical and health data center based on HBase and the synchronization of heterogeneous database Fang Shiwei to determine the data model, this paper puts forward the idea of HBase C-o-r modeling based on the E-R modeling of relational database, Then comprehensive analysis of Health department promulgated medical and Health metadata standards and the actual situation of some health institutions to achieve health information HBase Data Center construction. In order to realize the synchronization of data transparently to data center in heterogeneous relational database of medical institutions, the following schemes are proposed. First of all, in the data format proposed heterogeneous database production ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...
