Pi calculated to 62.8 trillion digits with a pair of 32-core AMD Epyc chips, 1TB RAM, 510TB disk space

From theregister.com

Switzerland’s University of Applied Sciences Graubünden has claimed the world record for calculating Pi, which it says it has computed to 62.8 trillion digits.

The university yesterday claimed the record, asserting that it beat previous attempts by 12.8 trillion digits, and did it 3.5 times faster than previous attempts at calculating the irrational ratio.

Helpfully, the uni has also published details of the hardware used for its feat.

A pair of 32-core AMD Epyc 7542 processors powered the uni’s rig. AMD states the CPU cores spend most of their time at 2.9GHz, can burst to 3.4GHz, have 128MB L3 cache and happily run 64 threads apiece. A server with 1TB of RAM was also employed, with Ubuntu Linux 20.04 installed on a pair of solid-state disks of unspecified size.
