CAP Bench: a benchmark suite for performance and energy evaluation of low-power many-core processors

摘要

The constant need for faster and more energy-efficient processors has been stimulating the development ofrnnew architectures, such as low-power many-core architectures. Researchers aiming to study these architecturesrnare challenged by peculiar characteristics of some components such as networks-on-chip and lack ofrnspecific tools to evaluate their performance. In this context, the goal of this paper is to present a benchmarkrnsuite to evaluate state-of-the-art low-power many-core architectures such as the Kalray MPPA-256 lowpowerrnprocessor, which features 256 compute cores in a single chip. The benchmark was designed and usedrnto highlight important aspects and details that need to be considered when developing parallel applicationsrnfor emerging low-power many-core architectures. As a result, this paper demonstrates that the benchmarkrnoffers a diverse suite of programs with regard to parallel patterns, job types, communication intensity, andrntask load strategies suitable for a broad understanding of performance and energy consumption ofMPPA-256rnand upcoming many-core architectures.
