### new server (lhcba2) is available now for the same use cases as lhcba1.
Please note this server is NOT a clone of lhcba1, in particular:
* it has more modern hardware and 4x times more RAM
* basis system is Ubuntu 22.04
* extra software is NOT installed
I ask every particular (potential) user of this server to let me know:
1) which extra software (under Ubuntu and/or CentOS7) you need on the
system level (don't forget to specify OS).
If required version is not default for particular OS, please
specify exact version.
If there is specific installation procedure, the link to the
installation documentation.
2) do you prefer interactive, throw batch system or mixed (f.e. batch
system during weekends) use of that server
3) do you need extra OS on that server (with explanation why you can't
use singularity).
Standard services which supposed to work already now:
* interactive login into Ubuntu (port 24) and CentOS7 (port 30)
* access to /work, /auto/data and /cvmfs (in both OS)
* /scratch (in Ubuntu)
* possibility to run singularity (in both OS)
* our batch system client (in both OS, with the same rules as on lhcba1)
Please note that any questions should be directed to me, central EDV is
NOT managing LHCb servers.
