In 2019, Google Cloud calculated Pi, an irrational number discovered thousands of years ago, to 31.4 trillion digits. This
This is the second time Google Cloud has set a record for the most digits of a mathematical constant. And in just three years, the number of calculated digits of Pi has tripled.
“This achievement testifies to the fact thatHow much faster is the Google Cloud infrastructure getting from year to year, says Google Cloud in a press release. “The core technology that makes this possible is the Compute Engine, Google Cloud's secure and customizable computing service, and its several recent additions and enhancements: the Compute Engine N2 family of machines, 100Gbps upstream throughput, Google Virtual NIC and balanced persistent disks."
The program that performed the calculation of 100 trilliondigits of Pi, called y-cruncher v0.7.8, its author is Alexander J. Yee. Google used the Chudnovsky algorithm and the n2-highmem-128 computing node with 128 virtual CPUs and 864 GB of RAM.
The calculation itself began on Thursday,October 14th at 12:45 a.m. Eastern Time in 2021 and ending on Monday March 21st at 12:16 a.m. Eastern Time in 2022. This is 157 days, 23 hours, 31 minutes and 7.651 seconds.
The storage size of this number is515 TB of 663 TB available, with total I/O of 43.5 PB read, 38.5 PB write, and 82 PB memory total.
