Title of presentation: |
Multitasking Polynomial Homotopy Continuation in PHCpack |
Abstract: |
Homotopy continuation methods to solve polynomial
systems scale very well on parallel machines. In this paper we examine
its parallel implementation on multiprocessor multicore workstations,
using threads. Preliminary timings indicate good speedups for basic
pleasingly parallel path tracking jobs. The use of multitasking will
lead to more efficient parallel implementations in a multi-tiered
approach. |
