18th December 2016 Our latest record was established as the followings: Declared record: The 100 quadrillionth (= 10^17-th) hexadecimal digit The main run computed 32 hexadecimal digits of pi starting at position 10^17, and the verification run computed 32 hexadecimal digits of pi starting at position 10^17 - 1. A comparison of these results showed that the hexadecimal digits of pi from the 10^17-th to the 10^17 + 22-nd digits were consistent. Then we are declaring the 100 quadrillionth hexadecimal digit as the new world record. Main run: Job start : 3rd December 2016 21:02:07 (JST) Job end : 18th December 2016 03:20:11 (JST) Total elapsed time : 320 hours 31 minutes Formula : Bellard's formula Verification run: Job start : 3rd December 2016 21:02:07 (JST) Job end : 18th December 2016 04:27:37 (JST) Total elapsed time : 320 hours 57 minutes Formula : Bellard's formula The hexadecimal digits of pi from the 10^17-th to the 10^17 + 15-th digits are: pi: A937EB59439E485E ^ The 10^17-th hexadecimal digit (First digit '3' for pi is not included in the above count.) The program was written by myself. The computer used was the Oakforest-PACS (Fujitsu PRIMERGY CX1640 M1 cluster) at the Joint Center for Advanced High Performance Computing (JCAHPC), which the University of Tokyo and University of Tsukuba jointly operate. Oakforest-PACS has 8208 compute nodes, each of which consists of Intel Xeon Phi 7250 processor, and Intel Omni-Path Architecture as an interconnect. The computation was performed during the test operation period. The main run and the verification run were each performed on 512 nodes. Due to the runtime limit for jobs, the main run and the verification run were each performed in 200 steps.
