The most common value of Pi is 3.1416, but it has grown longer over time as researchers try to find the most accurate calculation.
A team from Switzerland’s University of Applied Sciences Graubünden claims to have broken the world record for computing the mathematical constant Pi: it claims to have calculated 62.8 trillion digits of Pi.
Timothy Mullican, the current record holder, calculated up to 50 trillion digits and was recognized for his efforts last year.
The Swiss university’s team computed the new value in 108 days and 9 hours, according to the university. That’s 3.5 times faster than Mullican’s efforts and nearly twice as fast as Google’s 2019 record.
Emma Haruka Iwao and her colleagues used the power of 25 Google Cloud virtual machines to calculate Pi’s 31,415,926,535,897 digits in 121 days a few years ago.
According to The Register, the Swiss team used a system powered by two 32-core AMD Epyc 7542 processors with 1 TB of RAM and a program called y-Cruncher.
Its setup included 38 hard drives with 16 TB of storage space each, 34 of which were used for the process and four for storing the new Pi value.
The team did not use SSDs, despite the fact that their speed would have sped up the process, because the large number of write cycles required for Pi calculation would have resulted in excessive wear and tear on the SSDs, which aren’t cheap.
That wouldn’t have worked because the university wanted to show that it is possible to perform an extremely memory-intensive calculation with a limited budget and resources.
Guinness has yet to confirm the new record, but the university intends to publish the new and expanded value of Pi once it does.
