基于Iso-Doppler的非对称多核片上系统性能评估
Evaluating Asymmetric Multicore Systems-on-Chip using Iso-Metrics
摘要：
Dennard缩放的结束已经将功耗推到当前系统的一阶关注点，与性能相提并论。因此，近阈值电压计算（NTVC）已被提出作为一种潜在的手段，以解决有限的冷却能力的CMOS技术。在NTV中操作的硬件消耗显著更少的功率，以较低的频率为代价，并且因此降低了性能，以及增加了出错率。在本文中，我们调查，如果一个低功耗的片上系统，由ARM的不对称的大.小技术，可以替代传统的高性能多核处理器的功率/能量在不可靠的情况下。在我们的研究中，我们使用共轭梯度求解器，这是一种代表大量科学和工程代码执行的计算的算法。
英文摘要：
The end of Dennard scaling has pushed power consumption into a first order concern for current systems, on par with performance. As a result, near-threshold voltage computing (NTVC) has been proposed as a potential means to tackle the limited cooling capacity of CMOS technology. Hardware operating in NTV consumes significantly less power, at the cost of lower frequency, and thus reduced performance, as well as increased error rates. In this paper, we investigate if a low-power systems-on-chip, consisting of ARM's asymmetric big.LITTLE technology, can be an alternative to conventional high performance multicore processors in terms of power/energy in an unreliable scenario. For our study, we use the Conjugate Gradient solver, an algorithm representative of the computations performed by a large range of scientific and engineering codes.
