Abstract
A compiler creates a dependency graph for a function in an input program. The dependency graph includes nodes corresponding to commands in the function and edges that correspond to dependencies between the commands. The compiler performs a forward reachability analysis on the dependency graph to eliminate redundant dependencies. The compiler also adds a minimized set of back-edges to the dependency graph to enforce loop-carried resource dependencies in the input program. The compiler then allocates synchronization primitives provided by a multiprocessor computing system, such as semaphores, to the commands in the function of the input program based on the contents of the dependency graph.
