Okay, I'm going to bite the bullet and put off my dream of owning an alpha and buy a dual processor machine to help out in the testing! :-) I'm about as capable as a slinky when it comes to coding anything as involved as the FreeBSD SMP kernel, but I can test the hell out of it and hopefully be useful in that regard.. I also need to move to -CURRENT soon to get more up to date info into the book I'm writing.. so it was inevitable.. ;-) I don't know if anybody else is like me, but just thinking about the 3.0 release gets me all excited! SMP, ELF, IDE bus mastering, and so on and so on... It's certainly true that SMP has slowed down the release schedule of 3.0, with a super positive effect that FreeBSD 3.0 will be one rockin' step forward for FreeBSD! I'm really looking forward to it!! 8-) > Although somewhat stale, there are many useful links to whitepapers > on SMP in: > > http://www.freebsd.org/~fsmp/SMP/SMP.html Cool.
