So far, no one has commented on the fact that the article doesn't say *anything* negative about "RapidMind". My guess is that this: Program p = RM_BEGIN { In a, b; Out c; Value3f d = f * exp(a) * sin(b); c = d + a * 2.0f; } RM_END; Is turned into "stuff" plus a string. If this is true, you aren't going to get any warnings when you compile, even if you type in complete garbage. Also, I surmise that "RapidMind" is a commercial product and the history of commercial general purpose languages doesn't bode well for it. It also seems a bit out of place in the Linux world where there is generally an open source aspect to "stuff". (e.g. MySQL, QT) »
