Dear All,
As announced in conjunction with the recent SciComp maintenance (see message below), there are important changes to the JLab batch farm planned for the next weeks, with the retirement of Auger and Swif1.

If you are using the JLab batch farm, you should start transitioning to either Slurm or Swif2. As specified in the email below, documentation on how to migrate from Auger/Swif1 to Slurm/Swif2 is available on the SciComp web site.

To facilitate the exchange of information on this among CLAS Collaborators, a specific topic was created on the CLAS12 discourse forum at https://urldefense.proofpoint.com/v2/url?u=https-3A__clas12.discourse.group_c_jlab-2Dfarm-2Djobs_14&d=DwIFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=nhU86tu_xVxwkH2JyhlcQb1jyw6CUjquEwQhqpV3cJI&m=VrxddIGvvlC5aQgqOj4E2ck-nbw_LjZZWCYqdts3wnA4L8nALhrkJQdKzwy0ZsNJ&s=eu0SqznKMs-eDvxxGhnoczrfjEg5wTlr9jmnju-dxg0&e=  <https://urldefense.proofpoint.com/v2/url?u=https-3A__clas12.discourse.group_c_jlab-2Dfarm-2Djobs_14&d=DwIFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=nhU86tu_xVxwkH2JyhlcQb1jyw6CUjquEwQhqpV3cJI&m=VrxddIGvvlC5aQgqOj4E2ck-nbw_LjZZWCYqdts3wnA4L8nALhrkJQdKzwy0ZsNJ&s=eu0SqznKMs-eDvxxGhnoczrfjEg5wTlr9jmnju-dxg0&e= >.

> Reminder: Planned Maintenance Tuesday, January 18, 2022
> Slurm on the farm will be upgraded from version 19 to version 20. This includes security patches and minor feature updates. Jobs will continue to run during the upgrade. During the upgrade there will be periods where the Slurm commands and web pages are unresponsive. 
> On the LQCD AMD 21g cluster, ROCm 4.5.2 and system updates will be installed. 
> work file servers for the experimental halls and EIC will experience a brief interruption while patches are installed. 
> Open Science Grid nodes will be updated and rebooted
> Upcoming Retirement of Auger and swif version 1
> Beginning on March 1st, 2022 the Auger and swif version 1 commands will no longer be available. They have been superseded by the Slurm workload manager and by and swif version 2 (swif2): 
> Slurm includes GPU and MPI support, features absent in Auger. Detailed Documentation about Slurm at JLab <https://scicomp.jlab.org/docs/farm_slurm_batch> is available. 
> Swif2 is built on top of Slurm and supports running workflows with file staging, both locally and at remote sites. See the  SWIF2 manual <https://scicomp.jlab.org/swif2.html>  for details.
> For more information on the upcoming change and the changes to the job submission, please see the Migration Guide <https://scicomp.jlab.org/docs/farm_auger_migration_guide>.
> For further questions on Slurm, swif2, or the schedule, please submit a request to Serivce Now <https://urldefense.proofpoint.com/v2/url?u=https-3A__jlab.servicenowservices.com_sp-3Fid-3Duser-5Fservices-5Findex&d=DwIFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=nhU86tu_xVxwkH2JyhlcQb1jyw6CUjquEwQhqpV3cJI&m=VrxddIGvvlC5aQgqOj4E2ck-nbw_LjZZWCYqdts3wnA4L8nALhrkJQdKzwy0ZsNJ&s=i-UdeK3H62FORV2kJyf5Kv78TRzoEmx_3vnUKQvut6A&e= > or email helpdesk at jlab.org <mailto:helpdesk at jlab.org> 
> Schedule 
> On Tuesday, February 8th, jobs submitted using Auger or swif1 will have reduced scheduling capacity to encourage transition to Slurm and swif2.  
> On Tuesday, March 1st, the deprecated commands will be removed, Auger and SWIF1 services will be shut down, and documentation will be removed. The swif command will become an alias for swif2.
