ADA

In production since 27 September 2021, it is the smaller of the two machines and is composed of 71 nodes. Built on OpenStack (version Zed) can host virtual machines up to 96 vCPUs.

The HPC cloud infrastructure, named ADA, is built using OpenStack (version Zed).

Note

  • It is possible to access ADA via Horizon Dashboard at https://adacloud.hpc.cineca.it

  • For CLI access:

    • the certificate chain can be downloaded here ADA certificate
