The world record for calculating π is now held by a Swiss university, after calculating it to an accuracy of 62,8 trillion digits using a pair of 32-core AMD Epyc chips, 1TB of RAM and 510TB of disk space. It took only 108 days and 9 hours of computing operation.
The Swiss University of Applied Sciences Graubünden claims the world record for the calculation of π (Pi), which it says has been calculated with an accuracy of 62,8 trillion digits.
The university claims that won its previous calculation efforts by 12,8 trillion digits and did it 3,5 times faster. also posted details about the materials which he used for his achievement.
The heart of his equipment was a pair of AMD Epyc 7542, 32-core processors. AMD states that the CPU cores spend most of their time at 2.9GHz, can burst at 3.4GHz, have 128MB of L3 cache and run at 64 threads each. Also used was a server with 1TB of RAM, with OS Ubuntu Linux 20.04 installed on a pair of SSDs, of unspecified size. A JBOD accommodated 38 hard drives disks 7200RPM, which each had a capacity of 16TB.
Thirty-four of these disks were used to store the value of p. Hard disks were chosen over SSDs because SSD performance degrades over time, and the university's designers feared that intensive calculations could cause problems. In total, the university said 510TB of disk space was used.
The last ten digits of the 62,8 trillion, which are stored on these disks are 7817924264 and these are now the last known digits of p.
