Evaluation of Objectivity/AMS on the wide area network Original Research Article

In the coming generations of HEP experiments such as LHC, number of physicists will increase and spread around the world at unprecedented scale. The necessity to distribute the data near to the physicistsʹ home institutes also increases, and the effective utilization of the wide area network (WAN) becomes crucial. In this report we have monitored the detail behavior and the performance of Objectivity Advanced Multithreaded Server (AMS) as one of the candidate middle-ware for the world-wide distributed data analysis environment. The efficiency of single AMS transaction was found to be very low over the large latency WAN, and the cause and the possible implementation solution was studied.
