HEP Analysis Facility An Approach to Grid Computing

INTRODUCTION Protons, electrons, neutrons, neutrinos and even quarks are often featured in news of scientific discoveries. All of these, and a whole "zoo" of others, are tiny sub-atomic particles too small to be seen even with the microscopes. While molecules and atoms are the basic elements of familiar substances that we can see and feel, we have to "look" within atoms in order to learn about the "elementary" subatomic particles and to understand the nature of our Universe. The science of this study is called Particle Physics, Elementary Particle Physics or sometimes High Energy Physics (HEP). High processing speed, large memory space and big storage are the main requirements of the HEP research applications like ROOT, ALIROOT, GEANT etc. HEP Analysis Facility is a cluster designed in Scientific Linux Cern 5.5.
