SEE error-rate evaluation of an application implemented in COTS multicore/many-core processors

Abstract:

This paper evaluates the error rate of a memory-bound application implemented in different commercial-off-the-shelf multicore and many-core processors. To achieve this goal, two quantitative experiments are performed: fault-injection campaigns and radiation ground testing. In addition, this paper proposes an approach for pbkp_redicting the application error rate by combining the results issued from both types of experiments. The usefulness of the approach is illustrated by three case studies implemented in processors having different manufacturing technologies and architectures: 45-nm silicon-on-insulator (SOI) free-scale P2041 quad-core processor, 65-nm CMOS Adapteva Epiphany multicore processor, and 28-nm CMOS Kalray multipurpose processing array-256 many-core processor. The reliability of the processors for avionics is obtained from their experimental error rates extrapolated to avionic altitudes …
