The KABRU cluster will be mainly devoted to large scale numerical simulations in the area of Lattice Gauge Theory. The main aim is to understand the structure and properties of neutrons, protons, pions etc from first principle simulations of the theory called Quantum Chromodynamics (QCD). Despite the best efforts for more than twenty years it has not been possible to do reliable analytical calculations of these properties.

However, by exploiting the mathematical structure of Quantum Field Theories(QFT) of which QCD is a particular realisation it is possible to numerically simulate QCD on computers. This area of research has become very active internationally. The NSAC Subcommittee of USA has identified this area as No 1in importance for future research.

Even though the problems of QCD can be simulated on computers one requires very fast supercomputers. Many of the forefront problems would require 6 months to a year of running on Teraflop class supercomputers. KABRU is a machine of that class.

Problems that will be immediately simulated on KABRU are as follows:

1. Very accurate studies of confinement properties and of the QCD-string: this simulation is being carried out in collaboration with Dr Pushan Majumdar who is currently at the University of Graz

as a Lise-Meitner fellow.

2. Studies of the equation of state and sound velocity in QCD at finite temperature and density. This is being planned in collaboration with Profs Sourendu Gupta and Rajiv Gavai of the ILGTI at TIFR.
