This paper gives an overview on the structure and the use of Paclib, a new system for parallel algebraic computation on shared memory computers. Paclib has been developed as a professional tool for the simple design and efficient implementation of parallel algorithms in computer algebra and related areas. It provides concurrency, shared memory communication, non-determinism, speculative parallelism, streams and pipelining and a parallelized garbage collection. Paclib has been implemented on a Sequent Symmetry multiprocessor and is portable to other shared memory machines and workstations. Several algebraic algorithms have been implemented in Paclib and demonstrate the effectiveness of the system. 1, |
