![]() ![]() It was a fairly upmarket machine for the time with 12 physical cores and 24 hyperthreads, 96GBytes of Ram and 40TByes of disk storage. What we found remarkable then was that this had been achieved using nothing but a desktop computer. Yee & Shigeru Kondo computed pi to 5 trillion digits. Back in August 2010 we reported on the algorithm's first breakthough when Alexander J. The first scalable multi-threaded Pi-benchmark for multi-core systemsÄates from 2009 and has been breaking records ever since. The y-cruncher algorithm, which originated in "a high-school project that went a little too far" and is described as: Total I/O: 43.5 PB read, 38.5 PB written, 82 PB total.Total storage size: 663 TB available, 515 TB used.Total elapsed time: 157 days, 23 hours, 31 minutes and 7.651 seconds.Compute node: n2-highmem-128 with 128 vCPUs and 864 GB RAM.Program: y-cruncher v0.7.8, by Alexander J.The calculation required 82,000 terraabytes of data to be processed and its vital statistics are provided in this overview from the Google Cloud blog: If the sequence leading up to the 0 was read out loud at the rate of 1 digit per second, the feat would require 3.17 million years. ![]() The task took until Maand led to the discovery that the 100-trillionth decimal place of pi is 0. New Record From Google - 100 Trillion Digits Of PiÄ®mma Haruka Iwao, a Developer Advocate at Google Cloud, started a calculation to compute pi to 100 Trillion digits on Google Cloud from her home office on October 14 2021. ![]()
