We have a small cluster of about 40 nodes running RHEL 6. This cluster is managed using rocks which is convenient. To shut down the nodes, all I do is:
rocks run host halt
I can also install software to all the nodes, manage users etc very easily. We are looking to upgrade this using ubuntu 22 since RHEL6 is too old. I noticed there is openHPC but there are no binaries of it for ubuntu. So my question is what equivalent software are available for ubuntu for this?
goals:
- Provisioning of OS
- shutting down nodes
- Installing software
- managing and synching users
