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. As of November 2021, Piz Daint is ranked 20th on the TOP500.

History
The original Piz Daint Cray XC30 system was installed in December 2012.  This system was extended with Piz Dora, a Cray XC40 with 1,256 compute nodes, in 2013.  In October 2016, Piz Daint and Piz Dora were upgraded and combined into the current Cray XC50/XC40 system featuring Nvidia Tesla P100 GPUs.
