Err, I'm in that literature, dig a little, you'll find me. I'm quite familiar with clustering technology. While it is great that people are wiring up lots of machines and running MPI or whatever on them, they've been doing that for decades. It's only a recent thing that they started calling that "a machine". That's marketing, and it's fine marketing, but a bunch of machines, a network, and a library does not a machine make. Not to me it doesn't. I want to be able to exec a proces and have it land anywhere on the "machine", any CPU, I want controlling tty semantics, if I have 2300 processes in one process group then when I hit ^Z they had all better stop. Etc. A collection of machines that work together is called a network of machines, it's not one machine, it's a bunch of them. There's nothing wrong with getting a lot of use out of a pile of networked machines, it's a great thing. But it's no more a machine than the internet is a machine. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
