Sustainability in Computing: A Holistic View

绿色计算必须提供可持续的处理能力，具有高能效（更低的碳足迹）和更长的产品寿命（减少产品更换的需求）。虽然技术的进步已经显著降低了功率需求，但由于微尺度行为的不确定性、在极端规模计算中量化/优化能量成本或系统寿命的高复杂性以及非计算组件与单个计算系统的交互，它们带来了固有的挑战。该项目通过对新兴计算系统中的能源成本、碳足迹和产品寿命进行建模、分析和优化的整体、多尺度范式来应对这些挑战。

Green computing must provide sustainable processing capabilities with high energy efficiency (lower carbon footprint) and increased product longevity (reducing the need for product replacement). While advances in technology have afforded significant reduction in power requirements, they come with inherent challenges due to uncertainties in micro-scale behaviour, high complexity of quantifying/optimising energy cost or system lifetime in extreme scale computing, and the interaction of non-computing components with individual computing systems. This project addresses these challenges via a holistic, multi-scale paradigm for modelling, analysis, and optimisation of energy cost, carbon footprint, and product lifetime in emerging computing systems.
