Re: [Wlug] DistCC

by Ryan Caron

1) are you referring to the log that distcc generaties via distcc-config --set-log ? Or are you referring to your compile screens? If the compile screens, then DistCC is working, it just doesn't display it. Try setting the log file and reviewing it after a compile 2) I can't get the monitor to see anything either, thats why i stick with the log. One disadvantage to the log is that it does not log date & time, which a friend of mine (the other guy on the distcc servers page) is trying to resolve. 3) I'm just doing x86 at this point, but I'll install cross compile support for you on my machines. 4) Just send me your server names and I will add them to my page. I'm thinking about writing a script that will parse a web page for server names and plug it into the distcc hosts variable. That way the network would be more dynamic to changes in the host lists. I'll keep you all posted. On Thu, 4 Mar 2004 "Martin, Eric" wrote Subject: RE: [Wlug] DistCC 1) I would like to, but I'm having problems getting distcc to work (I think).

The most critical components, namely the kernel and glibc, are compiled for i386, i586, i686, and athlon.

Gentoo...

by Ryan Caron

Whoa, didn't mean to start a mini flame war! I think the portage system does wonders with the dependencies, and as I understand it portage is very BSD-like (I don't have any experience with BSD yet) with their package system. OK, one box boots up in 24 seconds (from GRUB menu to XDM login), and the other in 16 seconds (GRUB to CLI login). Now, thats a lot faster than default Red Hat installs, which can take minutes on a similarly capable machine. A good part of the faster bootup is that my Gentoo installation is, at least for now, much leaner than Red Hat and doesn't have to load as many daemons. But major distros like Red Hat, for compatibility sake, compile their code (or at least used to) as i386 for compatibility. Some have moved to i586. But my gentoo box is specifically compiled for the P4 with O3 compile flag. So that does speed things up a bit. Also, I run seti@home 24/7 on my personal boxes, so I never have any idle CPU percentages. On Red Hat seti@home would slow me down when I was really working the computer's resources. Haven't seen that happen yet in Gentoo. So, maybe its not the compiles that make it faster. But the capability to customize it, its inherent leanness (do I really want to install this if it takes 4 hours to compile)?, and its package system make it my linux distro of choice.

I have you don't any tests for over a network with latency like the internet? I'm wondering if, because the curernt distcc protocol is rather gross, one will get better compile times considering teh transfering of the files might take longer than actually compiling.

This list preforms reply-to munging, which has caused several people in the past to accidentally reply to the list when they had intended to send a private message. I like this: http://www.unicom.com/pw/reply-to-harmful.html And this: http://cr.yp.to/proto/replyto.html wrt. building from source vs. binary packages, of course there is a tradeoff. I use Debian myself, and might consider trying something else if I actually had some measurable amount of free time to screw around with building software. I think an important part of using a distribution with binary packages is learning how to make your own. (be it RH or Debian, etc) Once you do know how, dealing with that one package which isn't built the way you like it becomes much easier. -- Josh Huber

RE: [Wlug] Repartitioning for Installfest

by Martin, Eric

For me honestly, it has to do with the fact that I got sick and tired of RedHat. I got tired of *rpm -qa | grep (some dependancy)* Do I feel like it sped things up from redhat, yeah! Do I like the fact that I've learned a ton about linux, not RedHat, yeah. (Don't get me wrong, I'm not bashing RH, its just that *I* used RPMS as way too much of a crutch.) I like that I had evolution w/o ldap support, said "oh, I must have forgotten that flag", fixed the flag, and recompilied. Portage dl'd ldap for me, I didn't have to worry about deps...that's where gentoo really takes it for me.

I'll apologize for this one up front. That was supposed to be off list. Bad squirrelmail. Now for some justification so I don't seem like a total jerk. I've just read reports of using 3 days of CPU time to intall a gentoo system. My wimpy k6 system has over 98% idle cpu cycles - that's running i386 compiled debian code and a not totally trivial workload, it's a firewall, mail/web/dns server, and has a fair number of interactive users (15 as I write this, but it's still early in the day). My computer spends almost all of its time waiting for me. Any time that it doesn't spend waiting for me is spent waiting for I/O devices like disks and the network. If you want your computer to be faster, get yourself gobs of ram and run out of a ram disk. The cpu time is rarely the bottle. 3 days to save something that I'm only using 3% of... It's just not worth the hassle, imho. Scott _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug
