As CentOS 7 has reached its end of life on the 30th June, the Tier-1 computing farm is planning to update the Operating System on all user-interfaces and worker-nodes to AlmaLinux 9 by the end of the year.
To ease the transition to the new OS we prepared a new general-purpose user-interface (ui9-tier1.cr.cnaf.infn.it) where users can test their software and workflows.
To test job submission on AlmaLinux 9 worker nodes users can use the feature described here specifying in the submit file: +SingularityImage="cnaf-el9".
$ cat submit-alma9.sub # Unix submit description file # sleep.sub -- simple sleep job +SingularityImage = "cnaf-el9" Requirements = HasSingularity batch_name = Alma9-Sleep executable = sleep.sh arguments = 60 log = $(batch_name).log.$(Cluster).$(Process) output = $(batch_name).out.$(Cluster).$(Process) error = $(batch_name).err.$(Cluster).$(Process) should_transfer_files = Yes when_to_transfer_output = ON_EXIT queue
Missing Packages
In order to review the list of packages we install on our worker nodes, we selected only the strictly necessary ones.
If you see any missing packages, that you may need, please contact the support team ad users-support@lists.cnaf.infn.it.
