System-on-Chip (SoC) devices can be composed of low-power multicore processors combined with a small graphics accelerator
(or GPU) which offers a trade-off between computational capacity and low-power consumption. In this work we use the LLFI-GPU
fault injection tool on one of these devices to compare the sensitivity to soft errors of two different CUDA versions of matrix
multiplication benchmark. Specifically, we perform fault injection campaigns on a Jetson TK1 development kit, a board equipped
with a SoC including an NVIDIA ”Kepler“ Graphics Processing Unit (GPU). We evaluate the effect of modifying the size of the
problem and also the thread-block size on the behaviour of the algorithms. Our results show that the block version of the matrix
multiplication benchmark that leverages the shared memory of the GPU is not only faster than the element-wise version, but it is
also much more resilient to soft errors. We also use the cuda-gdb debugger to analyze the main causes of the crashes in the code
due to soft errors. Our experiments show that most of the errors are due to accesses to invalid positions of the different memories
of the GPU, which causes that the block version suffers a higher percentage of this kind of errors. [-]
