In this paper we assess and discuss the radiation sensitivity of a set of HPC applications executed on NVIDIA K20 GPGPUs. The occurrence of both radiation-induced silent data corruption and functional interruption will be experimentally addressed for Hotspot, LavaMD, and Matrix Transponse. Each of the tested codes requires a proper computational power and elaborates a different amount of data. Both these characteristics play a significant role in the application radiations sensitivity. Additionally, an evaluation of the error rate at sea level will be provided for all the tested codes.
