论文摘要
计算科学是基于一个计算范式，该计算范式对当今的技术条件不再有效。原因是甚至在处理器芯片内部，尤其是在系统组件之间的传输时间不可忽略不计。本文介绍了分散量的定量措施，这对于计算性能和能源消耗至关重要，并证明其价值如何随着不断变化的技术而增加。计算组件的时间行为（包括常用同步时钟时间的分散）对系统在各个级别的性能有关键的影响，如门级操作到超级计算。如果无法按比例缓解相关的转移时间，则相同的效果限制了研究的新材料/效果的效用。冯·诺伊曼（Von Neumann）的模型非常完美，但是现在它已在其有效性范围之外使用。还得出了考虑当前技术背景的转移时间的正确过程。
Computing science is based on a computing paradigm that is not valid anymore for today's technological conditions. The reason is that the transmission time even inside the processor chip, but especially between the components of the system, is not negligible anymore. The paper introduces a quantitative measure for dispersion, which is vital for both computing performance and energy consumption, and demonstrates how its value increased with the changing technology. The temporal behavior (including the dispersion of the commonly used synchronization clock time) of computing components has a critical impact on the system's performance at all levels, as demonstrated from gate-level operation to supercomputing. The same effect limits the utility of the researched new materials/effects if the related transfer time cannot be proportionally mitigated. von Neumann's model is perfect, but now it is used outside of its range of validity. The correct procedure to consider the transfer time for the present technological background is also derived.
