Multicore Systems: Challenges for Creating a Representative Fault Model for Fault Injection

The development of multicore applications presents a challenge to developers, especially those unfamiliar with the complex tasks of managing and debugging issues related to multiple processors. These technologies have been introduced in large scale systems such as PCs and then mobile and handheld devices due to their particular characteristics. Recently, usage of these architectures is becoming more and more interesting for embedded and safety-critical systems, but there is still some way to go. This work presents the breakthroughs and challenges identified on an on-going research project that intends to create an appropriate fault model in order to test (with fault injection) multicore applications for usage in safety critical domains.
