Transient faults continue to be a critical concern in a range of computing domains including: High-Performance Computing (HPC), scientific computing, and the automotive industry.

Abstract

Transient faults continue to be a critical concern in a range of computing domains including: High-Performance Computing (HPC), scientific computing, and the automotive industry. While radiation-induced faults have been well studied and understood in microprocessors, their impact on computations on Graphic Processing Units (GPU) has received less attention. GPUs are now being used in a large number of HPC and automotive markets. Mitigating the effects of transient faults requires a thorough understanding of the interaction between applications, system software, and the underlying hardware. Developing this understanding is quite challenging mainly due to our limited ability to capture and study cross-layer reliability interactions. In this paper, we consider the combination of neutron beam testing experiments with architectural fault injection experiments to gain a deeper understanding of the relationship between the vulnerability of GPUs and the underlying workload characteristics of applications targeted for GPU devices.
