It was ranked 8th on the TOP500 ranking of supercomputers until the end of 2015, higher than any other supercomputer in Europe.[2] At the end of 2016, the computing performance of Piz Daint was tripled to reach 25 petaflops; it thus became the third most powerful supercomputer in the world.[3][4][5][6] As of November 2020, Piz Daint is ranked 12th on the TOP500.[7][1]

History

The original Piz Daint Cray XC30 system was installed in December 2012.[8] This system was extended with Piz Dora, a Cray XC40 with 1256 compute nodes, in 2013.[9] In October 2016, Piz Daint and Piz Dora were upgraded and combined into the current Cray XC50/XC40 system featuring Nvidia Tesla P100 GPUs.
