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
Test submission on AlmaLinux 9
As some worker-nodes users can use the feature described here specifying in the submit file: +SingularityImage="cnaf-el9".are already running the new OS users can request to run on those machines by including these lines in their submit files:
| Code Block | ||||
|---|---|---|---|---|
| ||||
+SingularityImage = false
Requirements = (TARGET.OpSysAndVer == "AlmaLinux9") |
Please find below an example of submit file to test the submission on Alma9 machines.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
$ cat submit-alma9.sub # Unix submit description file # sleep.sub -- simple sleep job +SingularityImage = "cnaf-el9" false Requirements = (TARGET.OpSysAndVer == HasSingularity"AlmaLinux9") 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 |

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. |
Keep executing jobs on CentOS7
To keep submitting jobs on CentOS7 worker nodes users can use the feature described here specifying in the submit file: +SingularityImage="cnaf-el7".
This will allow you to run your job inside a singularity image identical to CentOS7 worker-nodes.

Please note that this mechanism is meant to be temporary, we will not upgrade the singularity image with any new packages. We strongly encourage all users to test their executables and migrate them to Alma9 as soon as possible. |
