Abstract

Abstract: This paper proposes a client dynamic self-adaptive replica selection algorithm in high energy physics grid environment. The algorithm predicts the replica selection based on the transfer histories, and it can also be configured easily for different applications. Mathematic derivation and experimental results are given to show that the algorithm can meet the requirements of high energy physics grid.

Key words: high energy physics, grid computing, replica selection
