Robust partitioning enforcement is a mandatory requirement in IMA1 systems. In this paper, we refine this requirement in the context of multicore processors and discuss a strategy to ensure it. We focus on a scenario in which several ARINC 653 partitions hosted on the same platform are executed at the same time on different cores. When this scenario is deployed on modern COTS2 hardware, robust partitioning may be impaired by inter-core conflicts sequences. The issue with such a deployment strategy lies in the isolated parallel execution of several partitions. The approach presented here aims at identifying conditions that entail inter-core conflicts with a sufficient level of detail. This representation helps identifying robust partitioning failure causes. Such information is a first step towards an acceptation of true parallelism in partitioned systems, i.e. deployment on multicores.
