The Cetus tool provides an infrastructure for research on multicore compiler optimizations that emphasizes automatic parallelization. The compiler infrastructure, which targets C programs, supports source-to-source transformations, is user-oriented and easy to handle, and provides the most important parallelization passes as well as the underlying enabling techniques.
Work stealing is an effective load-balancing strategy for multithreading, but when computations based on it underperform, traditional tools can't explain why. To resolve a computation's key performance obstacles, tools must pinpoint and quantify parallel idleness and overhead.
Programming for serial computing is already a difficult undertaking that we have yet to master; programming for parallel computing will only exacerbate this difficulty. Fortunately, tools and environments are beginning to emerge that will let us take advantage of multicore and many-core architectures in a more productive manner.
