Abstract
A new parallel sorting algorithm, Parasort, based upon Quicksort and two-way merging and suitable for implementation on shared memory multiprocessors is presented. An asynchronous parallel partitioning algorithm is used to distribute the work evenly amongst the processors during merging to ensure an even load balance which is crucial if high efficiency is to be achieved. The implementation of this parallel sorting algorithm on the Balance 8000 multiprocessor exhibits good speedup rates approaching linearity when compared to sequential quicksort.
