Many coarse-grained, explicitly parallel programs execute in phases delimited by barriers to preserve sets of cross process data dependencies. One of the major obstacles to optimizing these programs is the necessity to conservatively assume that any two statements in the program may execute concurrently. Consequently, compilers fail to take advantage of opportunities to apply optimizing transformations, particularly those designed to improve data locality, both within and across the phases of… CONTINUE READING
