I find it quite preposterous that the installer wants to run /bin/date on every single machine in my cluster! I have over 2700 machines!
Now because we have to install new software on ‘buildhosts’ because our shared software directory is shared to the cluster READ-ONLY, the buildhost has never before now connected to any of the compute nodes, meaning I have to ‘accept’ new entries to my known_hosts file.
This is quite frankly stupid and should be changed. At least give the user another option, or a way to provide the necessary data in another fashion.
I don’t think it is a good idea to ‘assume’ that the install script is run on the ‘master-node’, as situations like mine probably exist on larger clusters. Assuming everyone is on a small baby cluster is a good way to keep the larger cluster admins from wanting to install PGI. I know I sure don’t want to deal with this again …
