Thermal Neutrons: a Possible Threat for Supercomputers and Safety Critical Applications |
Abstract | ||
|---|---|---|
The high performance, high efficiency, and low cost of Commercial Off-The-Shelf (COTS) devices make them attractive for applications with strict reliability constraints. Today, COTS devices are adopted in HPC and safety-critical applications such as autonomous driving. Unfortunately, the cheap natural Boron widely used in COTS chip manufacturing process makes them highly susceptible to thermal (low energy) neutrons. In this paper, we demonstrate that thermal neutrons are a significant threat to COTS device reliability. For our study, we consider an AMD APU, three NVIDIA GPUs, an Intel accelerator, and an FPGA executing a relevant set of algorithms. We consider different scenarios that impact the thermal neutron flux such as weather, concrete walls and floors, and HPC liquid cooling systems. We show that thermal neutrons FIT rate could be comparable to the high energy neutron FIT rate. |
