When lexicographically sorting strings, it is not always necessary to inspect all symbols. For example, the lexicographical rank ofeuroparamongst the stringseureka,eurasia, andexcellsonly depends on its so calledrelevant prefixeuro. Thedistinguishing prefix sizeDof a set of strings is the number of symbols that actually need to be inspected to establish the lexicographical ordering of all strings. Efficient string sorters should beD-aware, i.e. their complexity should depend onDrather than on the total numberNof all symbols in all strings. While there are manyD-aware sorters in the sequential setting, there appear to be no such results in the PRAM model. We propose a framework yielding aD-aware modification of any existing PRAM string sorter. The derived algorithms are work-optimal with respect to their original counterpart: If the original algorithm requireswork, the derived one requireswork. The execution time increases only by a small factor that is logarithmic in the length of the longest relevant prefix. Our framework universally works for deterministic and randomized algorithms in all variations of the PRAM model, such that future improvements in (D-unaware) parallel string sorting will directly result in improvements inD-aware parallel string sorting.
