Preliminary results of SEU fault-injection on multicore processors in AMP mode

The current technological challenge for computing systems is to use multicore processors in order to ensure reliability, improve performance, and reduce power consumption. This paper presents a method and preliminary results of SEU fault-injection campaigns performed on multicore systems in asymmetric multi-processing mode. The target used for this purpose was a Quad-core processor. This work aims at validating the efficiency of TMR fault-tolerance method and to show the weakest variables of a given application running over multicore systems.
