This paper describes a parallel make utility, a method of executing compilations in parallel on loosely coupled UNIX systems; the resulting object modules are linked together when all needed compilations have been done. The authors implemented a subset of the Linda parallel computation primitives. All processors used the same local area network distributed file system, Sun NFS. The method is not particularly efficient because there is no gain from parallelism beyond four or five processors. The difficulty is not with the parallel computation primitives, but occurs because they are not used efficiently. Although possibilities of more efficient organization of the make utility are discussed at the end of the paper, they were not tried. Some similar work in other places suggests that adding at least an order of magnitude more processors could produce useful gains in the speed of a make utility with a different distribution of the work among the processors.
