Ny rekord for beregning af Pi-værdien

Memory-leverandøren KIOXIA og Linus Media Group har beregnet Pi-værdien med en hidtil uset præcision (in english).

KIOXIA Europe GmbH has announced that KIOXIA has collaborated with Linus Media Group, creator of Linus Tech Tips and other influential technology-focused YouTube channels, to set a new GUINNESS WORLD RECORDS title for the Most Accurate Value of Pi. A groundbreaking 300 trillion digits were calculated and officially verified and confirmed by Guinness World Records.

The record-smashing computation was enabled by a high-performance storage cluster comprising 2.2 petabytes (PB)[2] of 30.72 terabyte (TB) CM Series and 15.36 TB CD Series PCIe NVMe-based solid-state drives (SSDs) from KIOXIA.

These SSDs were configured in a network-attached storage environment connected to a dual-CPU compute server and ran for nearly seven and a half months.

- We knew breaking the Pi record with distributed network storage was going to be difficult - no one had really done it before due to the performance challenges associated with remote storage, says Jake Tivy, Writer & Host, Linus Media Group and he continues:

- Fortunately for us, the reliability and performance of KIOXIA's NVMe SSDs enabled us to run continuous, intensive compute operations at speeds up to 100+ GB/s for nearly seven months straight, without a single SSD failure.

- Attaining a Guinness World Records title for the most accurate value of Pi is a tremendous achievement, emphasising the courage of taking on a challenge and the power of great cooperation and teamwork, says Axel Stoermann, Vice President and CTO for Embedded Memory and SSD at KIOXIA Europe GmbH, and he adds:

- KIOXIA America's successful collaboration with Linus Media Group enabled the demonstration of the robust capabilities of our NVMe SSDs under the most demanding of workloads. We will continue to advance the capabilities of our flash memory and SSD technology to support supercomputing applications.

Pi (π) represents the mathematical constant expressing the ratio of a circle’s circumference to its diameter. Its decimal representation extends infinitely without repeating. While the community recognises records of 100 trillion and even 202 trillion digits have also been performed, this new record surpasses those by nearly 50% and significantly surpasses the previous official GUINNESS WORLD RECORDS benchmark of 62 trillion digits by a factor of nearly five.

The record-setting achievement was documented in a feature video released by the Linus Tech Tips YouTube channel, giving viewers a behind-the-scenes look at the project and revealing the final digit of the record-setting calculation: spoiler alert…the 300 trillionth digit of Pi is 5.
