This Pi Day, Emma Haruka Iwao has announced calculation of \(\pi\) to \( \pi \times 10^{13} = 31,\!415,\!926,\!535,\!897 \) digits, exceeding the previous record of 22 trillion digits set in November 2016.
This used y-cruncher, running Chudnovky’s algorithm. Chudnovky’s algorithm is \( \mathcal{O}(n(\log n)^3)\), making each record more impressive. In a blog post, Emma writes about the benefits of using a cloud cluster, saying the calculation ran on a virtual machine cluster, using
25 nodes for 111.8 days, or 2,795 machine-days (7.6 machine-years), during which time Google Cloud performed thousands of live migrations uninterrupted and with no impact on the calculation process.
Ways to access the digits and fun related bits and bobs are outlined in the blog post.
