ABSTRACT:
A quick freeze method and a clean freeze method allow for the halting of operation of all computing sections within a computing system upon detection of an error. In the quick freeze method, a first computing section detecting an error immediately halts operation. The first computing section notifies all adjacent computing sections of the detection of the error. Each computing section in the computing system, upon receiving notification of the detection of the error, immediately halts operation and notifies all adjacent computing sections of the detection of the error. In the clean freeze method, when a first computing section detects an error, all computing sections are notified of the detection of the error. When all computing sections of the computing system have been notified, all the computing sections within the computing system halt operation simultaneously. In order to allow for versatility, a computing system may be designed to allow the selection, at configuration, of either the clean freeze or the quick freeze method of halting operation of the computing system.
