Parallel processing infographic (IMAGE) Simons Foundation Caption Abacus leverages parallel computer processing to drastically speed up its calculations of how particles move about due to their gravitational attraction. A sequential processing approach (top) computes the gravitational tug between each pair of particles one by one. Parallel processing (bottom) instead divides the work across multiple computing cores, enabling the calculation of multiple particle interactions simultaneously.
