There will be several teams. Multiple 5-6 person teams unboxing nodes 
from their shipping boxes and sorting the materials for recycling. A 
couple cart runners going up and down the elevators into the data 
center. Then, there will be 5-6 3 person teams racking nodes and doing 
the cabling all at once. At the end of the train of people doing the 
hardware, they'll be about 3-4 people coming along and installing the 
nodes. (We use RedHat's kickstart and some special scripts we cooked 
up.) Almost all of this process is parallelized (probably everything 
but the lunch line.)

Once the nodes have a base install, they'll reboot and cfengine will 
run to make them "real" nodes.

We have a project manager and a lot of staff that have been putting a 
ton of time into this event.

To be running user jobs within 24 hours. We will do the benchmarking 
later after all the DOA hardware has been fixed.

The cluster hardware will be done in eight hours, and the software 
will simmer for up to 24 hours.

We have built out a beefy install infrastructure to support a lot of 
simultaneous installs...
