论文摘要
计算在天文学中的重要性不断增加，其对环境的影响也在增加。在分析数据或执行模拟时，大多数研究人员会引起人们对达到解决方案的时间，而不是对环境的影响。幸运的是，由于软件中更快的硬件或优化，通常会导致碳足迹较小。当通过超频处理器或使用超级计算机时，可以实现减少的壁通路时间时，情况并非如此。 解释的脚本语言的普及以及高性能工作站的总体可用性构成了对环境的巨大威胁。对于运行单核的趋势而不是采用有效的多核编程范例，可能会引起类似的问题。 在天文学中，计算是绿色房屋气体的顶级生产商之一，超过了望远镜操作。在这里，我希望提高对运行非优化代码对压倒计算机硬件的环境影响的认识。
The importance of computing in astronomy continues to increase, and so is its impact on the environment. When analyzing data or performing simulations, most researchers raise concerns about the time to reach a solution rather than its impact on the environment. Luckily, a reduced time-to-solution due to faster hardware or optimizations in the software generally also leads to a smaller carbon footprint. This is not the case when the reduced wall-clock time is achieved by overclocking the processor, or when using supercomputers. The increase in the popularity of interpreted scripting languages, and the general availability of high-performance workstations form a considerable threat to the environment. A similar concern can be raised about the trend of running single-core instead of adopting efficient many-core programming paradigms. In astronomy, computing is among the top producers of green-house gasses, surpassing telescope operations. Here I hope to raise the awareness of the environmental impact of running non-optimized code on overpowered computer hardware.
