A multiway merging network
- 117 Downloads
A multiway merging network is presented, which allows more flexible construction of parallel sorting networks. The merging network described here is composed of m k-way mergers and a combining network. It arranges k ordered lists each of length n into one ordered list in T(k)+[logmn] [log2k] [log2m] steps, where T(k) is the number of steps needed to sort k keys in order; and k and m are any integers no longer restricted to 2.
