== System hardware ==

=== CM nodes ===

- EnergyMeter kernel module has been updated 

=== ESB nodes ===

- remaining two ESB racks have been installed: now 75 ESB nodes present
- currently connected via IB EDR, to be changed to Extoll network later this year

=== DAM nodes ===

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

- BIOS update has been rolled out to all DAM nodes soon

=== 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.


=== Global resources ===

==== NAM ====

- a NAM SW implementation has been done, a test environment on the DAM is being prepared

=== File Systems ===

- DEEP-EST storage has been rebuilt for performance reasons
  - BeeGFS servers and clients have been updated
  - the SDV is de-coupled now meaning that the SDV nodes only mount `/sdv-work` (not `/work`) and the DEEP-EST nodes only mount `/work` (not `/sdv-work`)

- BeeGFS (`/work`) will get user quotas (see section "User management")

- It is 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] and see also
  the hint in the MOTD for efficient usage of the archive filesystem

- DCPMM usage within BeeGFS currently being tested on `dp-dam03`
  - more tests (with CentOS 8) to follow

== System software ==

=== SW updates ===

- new SLURM features are being integrated and will be rolled out in near future:
  - extended logging and improved resource management for jobs within a workflow
  - burst buffer pluggin

- 2020a Easybuild stage is currently being set up 

- ParaStationMPI version (5.4.6-1) has been installed and is used as default now



=== User management ===

==== BeeGFS Quotas ====

- a quota for the BeeGFS file system (mounted to /work) has been implemented
  - thresholds to be defined
