The ability to move 10s of TeraBytes in reasonable amounts of time are critical to many of the High Energy Physics applications.This paper examines the issues of high performance,high reliability tape storage systems,...
The only way Terabytes of data can be processed and analyzed in a reasonable time is by using parallel processing architectures.The Paralle ROOT Facility,PROOF,is s system for the parallel interactive analysis of such...
This article is about a piece of middle ware,allowing to convert a dump tape based Tertiary Storage System into a multi petabyte random access device with thousands of channels.Using typical caching mechanisms,the so...
Resources on a computational Grid are geographically istributed,heterogeneous in nature,owned by different individuals or organizations with their own scheduling policies,have different access cost models with dynamic...
This paper resents a new X-ray imaging method swing Laminography(SL) that is suitalble to perform non-destructive testing on the slender-shaped multi-layer samples.Computer simulations are made to compare the limited ...
Physics experiments that generate large amounts of data need to be able to share it with researchers around the world .High performance grids facilitate the distribution of such data to geographically remote places.Dy...
The Online Book-keeper(OBK) was developed to keep track of past data taking activity,as well as providing the hardware and software conditions during physics data taking to the scientists doing offline analysis.The ap...
This article summarizes the activities and the results of the Globus software evaluation,which was carried out in the framework of the INFN-GRID project.
The object-oriented tag database of the ZEUS experiment at HERA is based on Objectivity/DB.It is used to rapidly select events for physics analysis based on intuitive physical criteria.The total number of events curre...
One of the most challenging issues faced in HEP in recent years is the question of how to capitalise on software development and maintenance experience in a continuous manner.To capitalise inour context means to evalu...
