== System hardware ==


=== CM nodes ===

- the cluster nodes have direct EBR IB access to the SSSM storage nodes now (without using the IB <-> 40 GbE gateway)


=== ESB nodes ===

- all ESB nodes (`dp-esb[01-75]`) are using EDR Infiniband interconnect (no Extoll anymore)
- SSSM and AFSM file servers can be directly accessed through IB



=== DAM nodes ===

- DAM nodes are using EDR Infiniband (instead of using 40 GbE and Extoll) now
- SSSM and AFSM file servers can be directly accessed through IB


=== Network Federation Gateways ===

- with the all IB solution NFGWs are not needed anymore ! this also affects heterogenous jobs

- `dp-nfgw[01,04]` (IB EDR <-> 40GbE) still present, but not in use anymore

- remaining NFGWs are being used for BXI testing now: `dp-nfgw[02,03,05,06]`
 



=== SDV ===

- 4 node BXI test setup has been installed using the former GW nodes

- FPGA test nodes available for using FPGAs with oneAPI, OpenCL:
  - Arria10: deeper-sdv[09,10]
  - Stratix10: dp-sdv-esb[01,02]



{{{#!comment obsolete with removal of Extoll

==== NAM ====

- a NAM SW implementation has been done, a test environment on the DAM has been set up on dp-dam[09-16].
- for more information on NAM usage and an example, please refer to [wiki:Public/User_Guide/TAMPI_NAM NAM with TAMPI] page
}}}

=== File Systems ===

**please also refer to the**  [wiki:Filesystems Filesystems] **overview**

- quota has been added to `/tmp` on `deepv` to avoid congestion
- the All Flash Storage Module (AFSM) provides a fast work file system mounted to `/afsm` (symbolic link to `/work`) on all compute nodes (CM, DAM, ESB) and the login node (`deepv`)
- the older System Services and Storage Module (SSSM) work file system is obsolete, but still available at (`/work_old`) for data migration
- SSSM still serves the /usr/local/software file system, but
  - starting from Rocky 8 image `/usr/local` will be a local file system
  - `/usr/local/software` will be shared and provided by the SSSM storage
  - in addition to the !Easybuild software stack the shared `/usr/local/software` filesystem will contain manually installed software in a `legacy` subfolder
  

== System software ==

- ParaStation update (psmgmt) to 5.1.50-5 has been performed

=== OS 

- preparing update to Rocky 8.6 

- the decision was taken to use one Rocky linux image for all compute nodes

- transition from CentOS to Rocky Linux 8.5 has been finished on compute nodes

  - login node `deepv` has moved to Rocky linux 8 as well
  - file servers and master nodes to follow


=== !EasyBuild


- 2022 !EasyBuild stage is the default now
