  This report discusses the implementation of two parallel algorithms on a
distributed memory system for studying vortex dynamics in type-II
superconductors. These algorithms are the same as that implemented for
classical molecular dynamics simulation with short-range forces (Plimpton, J.
Comp. Phys. Vol.117, 1 (1995)). The run time for parallel algorithm is tested
on a system containing upto 4 processors and compared with that for vectorized
algorithm on a single processor for system size ranging from 120 to 4800
vortices.
