项目摘要
In the recent years, high energy physics experiments are getting the size bigger and bigger as the energy goes up. The data acquisition and processing system must deal with the large data size and complex data format. It requires advanced method for the data acquisition other than a larger capacity of the data transmission. An intelligent data preprocessing system is required to cope with the large data in addition to the data correction and compression in real time. Along this aim, a multi-processor system was developed using the TRANSPUTER of INMOS. The microprocessor has a facility of four communication ports for each other; LINK which provides an easy connection between microcomputer nodes in the array. For evaluation of such system in the experimental environment, an array system was designed to apply for the track finding processing based on the hit wire information of the central drift chamber of TRISTAN VENUS detector.In this research, we designed and built an interface circuit … More to squire the hit wire data from the CDC readout electronics. Also the software system for the parallel processing of the data in the array was developed. The interface is consist of the general control part and the dedicated part for this application which must be redesigned for the other application.The multiprocessor array under test consists of 20 TRANSPUTER nodes, the number of which is expandable easily. Although, an improvement of the distributed processing software is still under way, the performance of the system under the current version of the software were measured by loading the real experimental data. The results show the average processing time for the data is about a few milliseconds instead of 20 msec by Fujitsu M-780. The result shows the performance is enough for the present application for the VENUS experiment.A report of this development has been discussed. in the symposium on the Next Generation System of Data Acquisition in March 10-11, 1989, And the result is also reported at the conference of Computing in High Energy Physics '90 held at Santa Fe,New Mexico, April 9-13 1990.

近年来,随着能量的增加,高能物理实验的规模也越来越大。数据采集和处理系统必须处理大量的数据量和复杂的数据格式。这就要求采用先进的数据采集方法,而不是大容量的数据传输。除了真实的实时的数据校正和压缩外,还需要一个智能的数据预处理系统来科普大量的数据。沿着这一目标,利用INMOS的TRANSPUTER开发了一个多处理机系统。微处理器有一个设施的四个通信端口为对方;链接,它提供了一个简单的连接微计算机节点之间的阵列。为了在实验环境中对该系统进行评估,设计了一个阵列系统,应用于TRISTAN VENUS探测器中心漂移室的命中线信息进行寻轨处理,设计并搭建了接口电路 ...更多信息 从疾控中心读出电子设备中获取击线数据同时开发了阵列数据并行处理软件系统。该接口由通用控制部分和专用控制部分组成,专用控制部分需要重新设计以适应其他应用。被测多处理器阵列由20个TRANSPUTER节点组成,节点数量可方便地扩展。虽然,分布式处理软件的改进仍在进行中,通过加载真实的实验数据来测量在当前版本的软件下的系统的性能。结果表明,富士通M-780的平均数据处理时间约为几毫秒,而不是20毫秒。实验结果表明,该系统的性能满足VENUS实验的要求。在1989年3月10-11日举行的“下一代数据采集系统”讨论会上,我们介绍了这一结果,并在1990年4月9-13日在新墨西哥州圣达菲举行的“90高能物理计算会议”上作了报告。少
