    In 2004 Herb Sutter coined the same trend as The Free Lunch is Over4. machines - a way to structure your software to grow gracefully with your hardware. There are many other tools that fit this new modality, from lock-free algorithms and to co-routines, to channels3, not to mention actor-style message passing, among many other paradigms

    - X-Window over DOS - non-preemptive scheduling (thread runs until some external event occurs, mostly I/O) Running on different devices More efficient/scalable Concurrency levels ===== o Process level + Separate address space: better for security and stability + No shared memory: no data race + Can run on physically different hardware nodes

    Herb Sutter. Herb Sutter is a leading authority on software development. He is the best selling author of Exceptional C++ and three other books and hundreds of technical papers and articles, including the widely-cited essay "The Free Lunch Is Over" which described the software sea change now in progress to exploit increasingly parallel hardware.
