You could easily simulate this by configuring the dhcp server when you're partially done collecting MACS... and then just start your nodes building. Then you can find out if it adversely affects the rest of your MAC collection too.

(this may be what you were saying?) we could follow the parallel programming model of "bag of jobs" only in our case it would be a "bag of nodes to build". we set a limit as to the number of concurrent builders permitted and as one finishes another is queued up to the task... while this will not significantly improve performance, it takes the human interaction out of the loop. would be a reasonable interim solution until something better comes along. how attractive to do? that depends on the effort in making it happen and the amount of resources (programmers) taken away from developing a great new method to work on this interim technique. basically we all need a significantly faster build process that can handle 1000's of nodes simultaneous. stephen Brian Messenger wrote: > > While collecting mac addresses is it possible to image the nodes? > > My thought was that I could set up a simple dhcpd.conf, click the configure > PXE server button, next click start collecting button.
