Abstract:
Given two sparse polynomials f and g we want to compute their product.
One of the fastest methods is Johnson's algorithm (1974), which uses a
binary heap to simultaneously merge each f_i*g for i=1..#f. In this
talk we will describe how Johnson's algorithm may be parallelized for
multicore processors with very high performance. Our program is up to
6x faster with 4 cores than with 1.
