A multi-node processing network has a plurality of processors coupled in the
network.
The processors have a minimally operational state, e.g., upon being rebooted, and
have a fully operational state employing a code image. The processors, when in
the minimally operational state, request the code image from the network. The processors
have a non-volatile memory storing code for the minimally operational state, which
is sufficient to at least provide the code image request. A master source is coupled
in the network, the master source having at least a code image for broadcasting
on the network. The master source, upon receiving a code image request, waits a
predetermined time period, the predetermined time period allowing any additional
processor to reach the minimally operational state. Upon completion of the predetermined
time period, the master source broadcasts the code image on the network. The processor
may store the code image in volatile memory since it may easily be requested.
