Graphics Processing Units (GPUs) evolved from graphics-specific devices to general-purpose computing accelerators that scientists use to run large-scale simulations. Additionally, GPUs are very attractive for safety-critical applications that extensively use signal or image processing.
Unfortunately, while the performance and efficiency of GPUs are well established, their resilience characteristics in a large-scale computing system and safety critical-application have not been fully evaluated. The presence of complex scheduling circuitry, for instance, may significantly increase the parallel code error rate. Moreover, the parallel architecture of GPUs introduces novel radiation experiment challenges that need to be solved.
In this Chapter we present a detailed radiation test setup for GPUs, including some recommendations for parallel devices experiments. We also present some experimental results on the radiation sensitivity of modern GPUs, considering both low-level static analysis and typical parallel application behaviors under radiation.
