WebWorst case, the time required for a binary search is log_2(n) where n is the number of elements in the list. A simple parallel implementation breaks the master list into k sub-lists to be bin-searched by parallel threads. The resulting worst-case time for the binary search is log_2(n/k) realizing a theoretical decrease in the search time.
