The power of ZZ algorithms: French computers use desktops to break the world record of circumference rate operations created by supercomputers

 

Fabrice bellard, a French user, recently used an ordinary desktop computer to perform a feat of hitting the circumference rate operation record maintained by the supercomputer,He uses a desktop computer to calculate the circumference rate to the decimal point2.7 trillion bits,More than 47th digits after decimal point records created by t2k open supercomputer, which currently ranks last August in the world in 2.5 trillion.

Bellard uses a 2.93 GHz core i7 processor-based computer with 6 GB memory, the hard disk uses five raid-0 configured 7200.11 TB capacity Seagate, the system runs 64-bit Red Hat fedora 10 Operating System, and the file system uses Linux ext4.
The calculated circumference rate data occupies 103 GB of hard disk capacity. bellard spent days to calculate the result.
However, in this computation process, to keep ranking first, bellard used nine computers in the data verification phase to verify the data, so as to speed up the computation, if the computer is used to verify the calculation result, it will take an additional 13 days.
In the process of calculating the circumference rate, bellard uses the improved ovski equation.AlgorithmTo calculate the circumference rate, and use the baye-Bowen-lauf algorithm to verify the calculation result.
To commemorate his contribution to the circumference rate algorithm, this time bellard used the improved cherinovski equation algorithm named bellard. This algorithm is the fastest among all circles rate algorithms. Not only that, but Mr. bellard was also well known in the Linux community for compiling TCC compilers.
