| Abstract: | High energy physics (HEP) has always been a pioneer to develop information technologies. Modern HEP creates gigantic data sets which lead the huge challenges to the computer sciences. Scientists of HEP community developed the state-of-art computing platform to distribute, store and process data in PB scale. This report describes the evolution of high energy physics experiments and its computing technologies. The compute-Scienceing models and grid computing as the examples of data intensive computing platform are discussed in details. This report also introduces the application of grid computing in the LHC and BESIII experiments. The Chinese data intensive grid systems are are reported. The prospect of next genertion technologies such as cloud computing is discussed. |
