But with the wrong programming, a project can easily fail due to increased computation time. With careful mathematical thinking, a computer can be programmed to do just about anything efficiently. It’s a testament to the capability of his research team in optimising their system to carry out memory-intensive tasks with limited budget, hardware and human resources.
#Scientists calculate pi to digits full#
Keller said that while the full number of pi is irrelevant to most people, beating the world record is a byproduct of tuning the university’s HPC system for future computation tasks in the area of applied research and development such as modelling the entire universe or mapping the human genome. Now you might also be wondering what is the purpose of all this… The final calculation of 62,831,853,071,796 digits occupied a whopping 63 TB of storage space. They opted for HDDs instead of solid-state drives (SSDs) due to the nature of the calculation, as well as budget constraints.ĭuring the calculation process, 310 TB of storage space was devoted to swapping (a technique used by the researchers to offload work from the RAM onto the HDDs) and roughly 180 TB was used to back up cached calculation data. The university’s supercomputing system is equipped with a terabyte of memory and powered by a pair of AMD Epyc 7542 CPUs, supplemented by 38 hard disk drives (HDDs) with 16 TB capacity each. His team also did it in only 108 days, one-third of the calculation time held by the previous record. With their new high-performance computing (HPC) system, researchers at the Graubünden University of Applied Sciences have been sticking their fingers in many…pies.įor Keller Thomas, one of his research tasks involved calculating pi using the Chudnovsky algorithm to upwards of 62.8 trillion digits, besting the previous record of approximately 50 trillion digits by 12.8 trillion. Pi is an irrational number, which is a real number that cannot be expressed as the quotient of two integers, meaning the number goes on indefinitely.īut now Swiss scientists and a supercomputer just calculated pi to trillions of decimal points, breaking the world record for the most calculated digits of pi. Now you might be wondering… How many digits are there to the number pi? The answer is…there is no answer to that question. Here are the first million digits of pi, better start practising your memorisation skills now if you’re keen on participating in the pi recital contest next year!
Jokes aside, the number pi is 3.142 – but that’s just an approximation. His dad then says, what on Earth are they teaching you? Pies are obviously round! An old joke tells of a kid who comes home from school and says: Pi R squared!
