Abstract
The invention relates to a process for dynamically reconfiguring an information processing system ( ), particularly a so-called “SMP” symmetric multiprocessor system. The process comprises a preliminary step for detecting a failure risk of one of the components of the system (CPU ). Following this detection, the system ( ) is placed in a coherent, so-called “frozen” state in a first step with the aid of programs (J -J ) executing specific tasks. A second step consists of reconfiguring the system by reallocating/de-allocating all or some of the components (CPU -CPU ). In a third step, the component (CPU ) that presents a failure risk is isolated. The pending interruptions ( ) are processed and the current tasks ( ) are executed prior to the “freeze.” Likewise, the queues of tasks to be executed are purged prior to the “freeze.” Then, the subsequent tasks and interrupts are inhibited until a final step that consists of releasing the system ( ).
