As a consequence of increasing hardware fault rates, HPC systems face significant challenges in terms of reliability. Evaluating the error resilience of HPC applications is an essential step for building efficient fault-tolerant mechanisms for these applications. In this paper, we propose a methodology to characterize the resilience of OpenMP programs using fault-injection experiments. We find that the error resilience of OpenMP applications depends on the program structure and thread model;
