Piz Daint is a supercomputer in the Swiss National Supercomputing Centre, named after the mountain Piz Daint in the Swiss Alps.
[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.
[7][1] The original Piz Daint Cray XC30 system was installed in December 2012.
[8] This system was extended with Piz Dora, a Cray XC40 with 1,256 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.
