In my opinion, the idea of building a software abstraction layer in order to hide the complexity of the multicore processor from the programmer is pure folly. On the contrary, it is the multicore architecture that should be changed to address the complexity of software. I understand that Intel would like to safeguard their investment in and commitment to the thread-based model of parallelism, but the Berkeley group should have the courage to tell Intel that they're full of it. Intel is making a big mistake by emphasizing threads. Same goes for AMD. Multithreading is pure folly and no abstraction layer is going to solve the many problems of threaded programming. What is needed is a universal multicore architecture that can handle anything you can throw at it. It must implement fine-grained, deterministic parallelism in an MIMD configuration. In addition, the programmer should never have to think about the cores. The processor should be completely invisible. Contrary to conventional wisdom, the programming model must be implicitly parallel and explicity sequential. That's the only way to solve the programming difficulty problem. Intel and Microsoft are wasting their money if they apply pressure on the researchers at Berkeley to accomodate Intel's ridiculous thread-based approach to parallelism. Threads are not the future of parallelism. Find out why at the link below: Nightmare on Core Street: http://rebelscience.blogspot.com/2008/03/nightmare-on-core-street.html

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
