How does the fedora brewbuilder work?

[Mark]

Hey,

At this moment i'm looking into using distcc to use another computer
in my network to speed up the compilation progress but while looking
at that stuff i wondered how fedora is doing it. So is the build
system actually a cluster of 10? computers which are working with
distcc to compile all that stuff asap?

Some info about this would be interesting.

Thanx,
Mark.

Xen instances. There are some information at Fedora infrastructure wiki 
page. For more, ask in fedora infrastructure list

Brew is the internal Red Hat build system.  Koji is the new, open
build system used for Fedora>= 7.  I don't have any links to detailed
descriptions of how the builders are setup, but I believe they're
using Xen instances.  You can probably find more info poking around in
the wiki on in the fedora-infrastructure list archives.

FWIW, here's what koji gives as the current builders:

Hostname                           Arches
hammer2.fedora.redhat.com          i386,x86_64
ppc1.fedora.redhat.com             ppc,ppc64
ppc2.fedora.redhat.com             ppc,ppc64
ppc3.fedora.redhat.com             ppc,ppc64
ppc4.fedora.phx.redhat.com         ppc,ppc64
xenbuilder1.fedora.redhat.com      i386,x86_64
xenbuilder2.fedora.redhat.com      i386,x86_64
xenbuilder4.fedora.phx.redhat.com  i386,x86_64

I am grateful that I am not as judgmental as all those censorious,
self-righteous people around me.

Sorry, i meant Koji.
I did found some info on the wiki about koji and xen but i'm actually
surprised that the build system is so simple.. i expected a heavy
cluster of about 10 or more quad core cpu's that are all dedicated to
compiling programs but it doesn't seem to be the case. But than the
question still stands.. what kind of powerhouse is that koji
(xenbuilder) machine?

Actually, it's not.  There are several build hosts, but a single
package build runs on a single host and any parallelism comes from
sending separate complete builds to different hosts.
