Abstract
This is an embodiment for enabling calibration of the bus interfacing cell processors and I/O Controllers in a multi-cell system without rebooting the system in response to a change in the environment temperature. This is accomplished by periodically checking the intake temperature. If the temperature rise is less than a predefined threshold, no action is taken. If the temperature rise is more than a predefined threshold, external interfaces are disabled, cell operations are halted and calibration is performed. Once the calibration is completed, cell operations are resumed and external interfaces are re-enabled.
