Abstract
The end of Dennard scaling has promoted low power consumption into a firstorder
concern for computing systems. However, conventional power conservation
schemes such as voltage and frequency scaling are reaching their limits when used in
performance-constrained environments. New technologies are required to break the
power wall while sustaining performance on future processors. Low-power embedded
processors and near-threshold voltage computing (NTVC) have been proposed as viable
solutions to tackle the power wall in future computing systems. Unfortunately, these
technologies may also compromise per-core performance and, in the case of NTVC,
xreliability. These limitations would make them unsuitable for HPC systems and
datacenters. In order to demonstrate that emerging low-power processing technologies
can effectively replace conventional technologies, this study relies on ARM’s
big.LITTLE processors as both an actual and emulation platform, and state-of-the-art
implementations of the CG solver. For NTVC in particular, the paper describes how
efficient algorithm-based fault tolerance schemes preserve the power and energy
benefits of very low voltage operation.
