Description
Systems on Chip (SoCs), originally targeted for mobile and embedded technology, are becoming attractive for HEP and HPC scientific communities, given their low cost, huge worldwide shipments, low power consumption and increasing processing power - mostly associated with their GPUs.
A variety of development boards are currently available, making it foreseeable to use these power-efficient platforms in a standard computing center configuration.
We discuss hardware limitations and programming constraints of low power solutions, namely ARM-based SoCs and Intel (Avoton) SoCs. Finally, we present some preliminary evaluations of the performances of SoC architectures running non-trivial scientific applications exploiting both the CPU and GPU available on the low power chip: results get particularly encouraging when considering workloads with low memory requirements and/or image processing.
