= Latest news on the DEEP-EST prototype system =

This is a summary of the latest news concerning the system. For a list of known problems related to the system, please refer to [wiki:Public/User_Guide/PaS this page].

== System hardware ==

=== CM nodes ===

 

=== ESB nodes ===

- currently only 1 rack installed in the system (25 nodes).
- installation of the 2 remaining racks is scheduled for mid of May

=== DAM nodes ===

- all nodes still run in app-direct mode for the DCPMM (see #2366)

=== Network Federation Gateways ===

- two gateway nodes for IB <-> Extoll bridging between CM/ESB and DAM are available for the users

- for an example on how to use the gateway nodes and for further information, 
  please refer to the [wiki:/Public/User_Guide/Batch_system#HeterogeneousjobswithMPIcommunicationacrossmodules batchsystem] wiki page.

==== NAM ====

- A mock-up of the NAM management software will be developed in the next weeks to allow working in parallel on the development of the real NAM manager and its integration with the system software (`psmgmnt` and `psslurm`).
}}}

=== File Systems ===

- The old shared file system `/sdv-work` (from previous DEEP projects) currently does not work. Metadata are still available (files and directories can be seen), but data is not accessible. Please contact deepest-sup@fz-juelich.de if you need to recover data from the file system. 

- Still ongoing investigations on the performance of the shared file system `/work` (BeeGFS).

- It is now possible to access the `$ARCHIVE` file system from the `deepv` login node under `/arch`. For more information about `$ARCHIVE`, please refer to the [wiki:Filesystems Filesystems page].


== System software ==

=== SW updates ===

- new SLURM version 19.5.5 with workflow support has been rolled out
  - information on how to use workflows have been added [https://deeptrac.zam.kfa-juelich.de:8443/trac/wiki/Public/User_Guide/Batch_system#Workflows here].
  - please, report any problems found 

- new ParaStationMPI version (5.4.5-2) is installed and used as default now
  - Pending: Install software packages that depend on psmpi also with the new version

{{{#!comment
- modules successfully tested in the Devel stage will be included in the production (default) stage
  - currently, the latest ParaStationMPI (including pscom) can be tested in the Devel stage

==== QoS ====

- the quality of service groups (QoS) within Slurm (determining the jobs priority) are currently being re-organized with regards to the accounting introduced with the EAP

- please, report any issues in starting jobs or in specifying an account for your jobs using the `-A` option

==== BeeGFS Quotas ====

- it's currently under consideration to implement a quota for the BeeGFS file system (mounted to /work)
