http://staff.ustc.edu.cn/~csli/graduate/algorithms/book6/chap30.htm WebThe EREW PRAM is the weakest among the four basic variants. A CREW PRAM can simulate an EREW one. Both can be simulated by the more powerful CRCW PRAM. An algorithm designed for the common PRAM can be executed on a priority or arbitrary PRAM and exhibit similar complexity. The same holds for an arbitrary PRAM algorithm when …

WebIn this paper, we present a new parallel algorithm to generate a short addition chain for x. The algorithm has running time O(log 2 n) using polynomial number processors under EREW PRAM (exclusive read exclusive write parallel random access machine). The algorithm is faster than previous algorithms and is based on binary method. Keywords ... http://staff.ustc.edu.cn/~csli/graduate/algorithms/book6/chap30.htm
