The uni's rig computations were significantly faster than the record set by the cloudy 96-vCPU effort that Googler Emma Haruka Iwao employed over 121 days to calculate Pi to 31.4 trillion decimal places in 2019.Īn app called y-Cruncher did the work, and was configured to move data in parallel from the server to the 34 disks at around 8.5GB/sec. Linux gods at last turn their gaze to Pi 400: Computer-in-a-keyboard receives mainline kernel support with v5.14.Pi(e) Day of the Century is upon us! Time to celebrate 3/14/15 in style, surely?.In November 2016 I made a data set with one trillion decimal digits.
Data sets with more digits are available from and from Google drive. That's Numberwang! Google Cloud staffer breaks record for most accurate Pi calculation If you’re only interested in the first thousand or the first million digits of pi, you can download them as text files (.txt) directly from the links below.Hard disks were chosen over SSDs because SSD performance degrades over time and the university's designers feared their intensive calculations could cause problems.

Accuracy 22 459 157 718 361 decimal digits 18 651 926 753 033 hexadecimal digits. A JBOD housed 38 7200RPM hard disks, each with 16TB capacity.
