The next Effective Concurrency column, “Writing a Generalized Concurrent Queue”, just went live on DDJ’s site, and also appears in the print magazine.
From the article:
Last month , I showed code for a lock-free queue that supported the limited case of exactly two threads—one producer, and one consumer. That’s useful, but maybe not as exciting now that our first rush of lock-free coding glee has worn off. This month, let’s tackle the general problem of supporting multiple producers and multiple consumers with as much concurrency as possible. The code in this article uses four main design techniques: …
