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 this page.

Last update: 2021-01-12

System hardware

ESB nodes

  • in CW51 the update of the first ESB rack started for using Extoll Fabri3 network (instead of IB)
    • work is still ongoing

DAM nodes

  • Persistent memory for nodes dp-dam[03-16] has been extended to 3 TB with next maintenance (CW51)

Network Federation Gateways

  • Gateway nodes have been completed in CW51 to the final layout:
  • 2 NF-GW EDR/Fabri3
  • 2x NF-GW 40GbE/Fabri3
  • 2x NF-GW EDR/40GbE
  • due to the ongoing Fabri3 installation two of the NF-GWs (the ones equipped with Fabri3 PCIe cards) are not in operation yet
  • for an example on how to use the gateway nodes and for further information, please refer to the batchsystem wiki page.

Global resources

NAM

  • a NAM SW implementation has been done, a test environment on the DAM has been set up on dp-dam[09-16].

File Systems

  • a new All Flash Storage Module (AFSM) is going to be added to the system in January 2020
  • 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 do not mount /work anymore and the DEEP-EST (CM,DAM,ESB) nodes only mount /work (not /sdv-work)
  • BeeGFS (/work) user quotas is in place now (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 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 different kernel versions) being done

System software

SW updates

  • new SLURM features are being integrated and will be rolled out soon:
    • extended logging and improved resource management for jobs within a workflow
    • burst buffer plugin
  • 2020 Easybuild stage is being set up
  • Intel oneAPI Beta 10 version has been installed to /usr/local/intel/oneapi

User management

BeeGFS Quotas

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