PLUGGING ANTI AND OUTPUT DEPENDENCE REMOVAL TECHNIQUES INTO LOOP PARALLELIZATION ALGORITHM

In this paper we shortly survey some loop transformation techniques wh ich break anti or output dependences, or artificial cycles involving s uch 'false' dependences, These false dependences are removed through t he introduction of temporary buffer arrays, Next we show how to plug t hese techniques into loop parallelization algorithms (such as Alien an d Kennedy's algorithm). The goal is to extract as many parallel loops as the intrinsic degree of parallelism of the nest authorizes, while a voiding a full memory expansion, We try to reduce the number of tempor ary arrays that we introduce, as well as their dimension.
