ABSTRACT:
A method, apparatus, and computer instructions for managing interrupts using a set of presentation controllers. A first interrupt server is identified in the set of interrupt servers to handle the interrupt in response to receiving an interrupt signal. The set of interrupt servers constituting a server pool are linked in a circular list using a set of identifiers. The message representing the interrupt is sent to a second interrupt server, such as in a second presentation controller in the set of presentation controllers based on an identifier identifying the second interrupt server in the set of interrupt servers, if the first interrupt server is unable to handle the interrupt. The identifier is found within the first interrupt controller. The interrupt is passed to different interrupt servers potentially associated with different presentation controllers within the circular list.
