A computer system of a number of processing nodes operate either in a loop
configuration or off of a common bus with high speed, high performance
wide bandwidth characteristics. The processing nodes in the system are
also interconnected by a separate narrow bandwidth, low frequency recovery
bus. When problems arise with node operations on the high speed bus,
operations are transferred to the low frequency recovery bus and continue
there at a slower rate for recovery operations. The recovery technique may
be used to increase system speed and performance on a dynamic basis.
