| | | | | | | | | |     137658 [peter.kwangj] Lothar,
| | | | | | | | | |     137759 [flaig sancta] I think the "wal-mart argument" is quite an important one. Apart from explicitly creating threads, it would be nice if the Ruby system could be taught to automatically recognize parallelizable code and optimally distribute it across a multiprocessor system -- implicitly. That would be a big advange for high-level programming in general! I do not know the state of the art in this, I only remember that the Atari/Inmos guys failed do do this in Occam, back in the 1980s. Do you think there is a serious chance to get such a thing working?

The philosophy of increasing processing power by simply increasing clock speeds seems to have reached its limits. Any further advancement will require an intelligent combination of hard- and software. One which even Wal-Mart customers can handle ;-) .
