Abstract: Conventional processing techniques for pipelined vector processors such as the Cray-XMP, or data-parallel computers, such as the Connection Machines, are generally applied only to independent multiple data prcessing. This paper describes a vector processing method for multiple processings including parallel rewriting of dynamic data strutures with shared elements, and for mutiple procesings that may rewrite the same data item multiple times. This method enables vector processing when entering mutiple data items into a hash table, address calculation sorting, and many other algorithms that handle lists, trees, graphs and other types of symbolic data structures. This method is aplied to several algorithms; consequently, the peformance is improved by a fator of ten on a Hitachi S-810.
