I've jsut installed Gentoo on a spare P200 I had lying about and I've been
playing with distcc, which distributes the compilation processes. I was
hoping that I could do most the work on my P3 1.2G box, but distcc didn't
work quite as I expected it to. I probably just need to mess around with the
settings some more, until it works. The slow machine was sharing some processes
and doing some locally, the fast machine was usually quite idle. Distcc
isn't clever enough to tell which computers aren't doing anything. And when
I got home from the Tuesday Club I found that the slow machine had seg
faulted whilst compiling glibc with distcc. I know that some programs don't
play nicely with distcc, maybe glibc is one of them.

Once I've got glibc installed I'm going to give openmosix a try. It's more
intelligent than distcc and can share most processes, although it's not good
for things like compilation because the processes are too short for
migration. Ususally a process has to be running for more than 5 seconds
before it can be migrated. But I'm hoping that a mixture of openmosix and
distcc will make things much faster. Or if not at least have some fun on the
way.
