No, son. Maybe I've been around a bit longer than you, but we were accomplishing everything that people are trying to do with threads with simple forks some 20 years ago. And the coding was much simpler, easier to debug, easier to maintain, easier to prove correct.

If the answer is "threads", you asked the wrong question. Threads suck. Event-driven programs and processes are a much cleaner model, with a far better defect ratio.

And a forked program cluster will use your two, four, and 20-way core boxes just fine. No need to introduce the bizarre complexity of threads.

Using threads are like using globals... sure you can do it, but it requires a lot more care. Using fork is like having everything be local to its code and data, which is what you want in a large system anyway.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
