我们进行了完整可观察到的宇宙的第一个数值n个体仿真（Deus“ Dark Energy Universe MINULATION“ fur“ Full Universe Run”）。这已经在自适应网状精炼网格上演变了500亿个颗粒，沿着宇宙的整个进化历史以及在6个大小的长度尺度上，从银河系的大小到整个可观察到的宇宙的大小，沿着宇宙的整个进化史和6个大小的长度尺度上进化了200亿个颗粒。 。迄今为止，这是有史以来最大，最先进的宇宙学模拟。它提供了有关宇宙中最大结构的形成和演变的独特信息，以及对未来观察计划的特殊支持，该计划致力于绘制宇宙中物质和星系的分布。该仿真已在4752（5040）的Bull SuperCulie的薄节点上运行，使用300吨内存的计算时间使用300吨内存。在整个运行过程中生成了约50个数据。使用高级和创新的减少工作流，有用的存储数据数量已减少到500 tbytes。
We have performed the first-ever numerical N- body simulation of the full observable universe (DEUS "Dark Energy Universe Simulation" FUR "Full Universe Run"). This has evolved 550 billion particles on an Adaptive Mesh Refinement grid with more than two trillion computing points along the entire evolutionary history of the universe and across 6 order of magnitudes length scales, from the size of the Milky Way to that of the whole observable universe. To date, this is the largest and most advanced cosmological simulation ever run. It provides unique information on the formation and evolution of the largest structure in the universe and an exceptional support to future observational programs dedicated to mapping the distribution of matter and galaxies in the universe. The simulation has run on 4752 (of 5040) thin nodes of BULL supercomputer CURIE, using more than 300 TB of memory for 10 million hours of computing time. About 50 PBytes of data were generated throughout the run. Using an advanced and innovative reduction workflow the amount of useful stored data has been reduced to 500 TBytes.
