ABSTRACT
Computation of magnetic field due to various types of conductors plays an important role in building an air core magnet. A new and efficient parallel software SUPER has been developed to design a superconducting air core magnet which will be used in the design of 2.5 Gev electron storage ring at Centre for Advanced Technology (CAT), India. Biot - Saverts law was taken as the basic principle for the computation of magnetic field at a desired point in the space due to a set of current carrying conductors. Each conductor in this set can be composed of a basic set of 3 straight conductors in X, Y and Z directions and 3 circular shaped conductors in 3 basic XZ, ZY and YX planes. By calculating the magnetic field at a very large number of points one can compute energy stored and inductance of large accelerator magnets, energy storage chokes and large size transformers. Since the computation of field at any point is an independent task the computing load can be distributed among several processors which substantially reduces the run time. A master slave model for this purpose has been developed using Parallel Virtual Machine (PVM) on DEC Alpha 500 computer systems. Performance analysis of sequential and parallel virsions will be disscussed.
