A Japanese man claims pi to 10 trillion digits behind the comma are calculated, with which the record of last year would have doubled. The man would be 191 days of computing time have needed. A lot of details about the record are not there yet.
The Japanese publishes his claim under the pseudonym JA0HXV, behind which the name Shigeru Kondo in disguise. It turns out that the man who in August last year pi to 5 trillion digits behind the comma are calculated.
Kondo began, this time in October 2010 with his attempt, and had the calculation in his own words more than once to re-initialize because of hardeschijfproblemen. On 16 October he reached, however, the milestone of 10 billion, writes the Japanese on his blog, where he was the verification of the calculation count.
Kondo promises as soon as possible more details about his record to publish. Not known for example what kind of system he used. However, it is likely that he reset the software by Alexander J. Yee has used. This program, y-cruncher, can have many cores and different hard drives, use the calculation and it is easy to continue to count after a hardware failure. Last year, used Kondo a zelfbouwsysteem with Two Xeon X5680 processors and more than 22TB-disk space.
