[Scons-users] visualize build parallelism, duration of build steps?

[Gabe Black]

Hi folks, sorry if this is a really obvious question, but is there a
command line flag or tool or something to visualize how parallel a SCons
build is, if there are any bottlenecks, if there are abnormally long
running build steps, etc?

I don't have an immediate pressing need for a tool like that, but I think
it might be helpful identifying places our build could be tightened up. It
could and also help get a rough idea of how well the build would scale to a
very parallel build machine, ie. what might build time be with 32 cores? 64
cores? 128 cores? etc. How much memory would you need for 128 cores to
avoid memory bottlenecks?

Somewhat on that topic, are there any relatively easy to set up distributed
build mechanisms for SCons? I'm sure you could plug distcc into it for
instance, but is there anything which has some nice, turn key(ish?)
integration?

Thanks!
Gabe
