Re: Google employee 100 trillion digits of pi

"Don't be evil."

How much climate change was caused by this calculation?  How many resources were wasted?

Calculating 100 trillion digits of PI is like asking how angels can dance on the head of a pin?  Twelve digits will get you to Mars.

: Google has successfully calculated 100 trillion digits of π, setting a new world record in the process. This isn't the first time Google has topped the leaderboard. In 2019, the search giant became the first to use a commercial cloud service and solid state drives to set the Pi record at 31.4 trillion digits calculated.

A team from the University of Applied Sciences of the Grisons swiped the record last year, pushing the total up to 62.8 trillion decimal places.

Like before, Google used y-cruncher to perform calculations. This time around, the Compute Engine was configured with 128 vCPUs, 864 GB of RAM and 100 Gbps of egress bandwidth. For comparison, the 2019 calculation had just 16 Gbps of egress bandwidth.

The program ran for a total of 157 days, 23 hours, 31 minutes and 7.651 seconds, utilizing 43.5 PB of reads and 38.5 PB of writes in the process.
