Ah! Useful for finding an announcement - maybe not. otoh the forums do allow Q&A without subscription.
And requiring subscriptions is necessary to avoid spam. Being able to hash things out without checking yet another bulletin board regularly is really nice. (Though things did get out of hand, and rather heated on the shootout list).
In this case, there was no announcement
Okay.

Yeah, I found that, eventually. The thing is, it'd be nice to have clarifications to the benchmark spec caused by such creative attempts on the benchmark page somewhere. A seperate "benchmark clarifications" forum might also work, but be less convenient. Also, even though I brought up the concern, that the manager thread might not be considered acceptable, I personally think the seperate threads should be accepted. I see the manager thread as just an implementation technique for symmetrically synchronizing the other threads. It's not a primitive, like a built in "barrier n" function would be. Of course, neither is the "lock this and see what else is there" technique, which I see as being at the same level. I guess this goes to my dissatisfaction with the "same *exact* way" evolution of the shootout, which is now a lost battle. Is the task "synchronize these four threads, two at a time", or "synchronize these four threads, two at a time using the most primitive facilities available in your language that most closely resemble the orthodox parallelism paradigm". I don't, for example, see a good way to do this synchronization in Occam without using a manager thread. In fact, the linked paper describes the meeting place as being "a server" which has the connotation to me of being at least another thread, though none of the example programs use a seperate thread. Anyways, your shootout, your hard work, your rules, but having rulings on what's acceptable be easier to find would be nice.
And that was already commented on by folk on this mailing-list.
Right, but no pointer to it, and it wasn't immediately obvious to me. -- Aaron Denney -><-
