Abstract
A fault tolerator for an operations controller of a multiple node fault tolerant processing system having a data memory for storing the content of all received error free messages, an error file for storing the content of all received inner node error reports, an error handler for generating a base penalty count for each node based on the content of the errors recorded in the error file and for excluding each node from the operation of the multiple node processing system whose base penalty count exceeds an exclusion threshold. The fault tolerator also includes a synchronizer interface for passing the selected fields of the received messages to a synchronizer, a scheduler interface for passing selected information to a scheduler, and a message interface which stores the error free messages in the data memory and passes the selected fields of the messages to the synchronizer.
