An Optimized External Sort Algorithm

  • Xin Zhou

A novel external sorting paradigm whereby disk access is minimized is presented. It is much faster (up to 10 times) than the traditional 2-way merge sort in most cases. In addition, it does not require extra space on the hard disk for temporary storage.
