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 Overview (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 certificatecheck that the version installed is 6.5 or 6.6 with “openstack –version” command. With greater versions some commands might not work.
