Abstract

We present the prototype of an open source data transfer tool kit. It provides an easy to use ‘drag-and-drop’ web interface for users to transfer files between institutions that do not have a grid infrastructure in place. The underlying technology leverages standard grid technologies. e.g. automatic generation of X.509 certificates, but remains completely hidden from the user.

Highlights

  • The LHC experiments have built a global e-Infrastructure in order to handle hundreds of petabytes of data and massive compute requirements

  • Just as in particle physics they often require large data sets to be moved between analysis locations

  • This project makes use of the fact that there is nothing intrinsically particle physics specific in the LHC e-Infrastructure, but focuses on the adaptations needed to extend this infrastructure to institutions that do not have a grid infrastructure in place

Summary

Introduction

The LHC experiments have built a global e-Infrastructure in order to handle hundreds of petabytes of data and massive compute requirements. At the same time many areas of academic research are increasingly catching up with the LHC experiments when it comes to data volumes. Just as in particle physics they often require large data sets to be moved between analysis locations. This project makes use of the fact that there is nothing intrinsically particle physics specific in the LHC e-Infrastructure, but focuses on the adaptations needed to extend this infrastructure to institutions that do not have a grid infrastructure in place. Many of them prefer to use graphical interfaces, rather than the command line tools common to particle physics
