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: 2021-09-08

System hardware

ESB nodes

  • the first ESB rack (nodes dp-esb[01-25]) is planned to be revised to use IB again (instead of Extoll interconnect)
    • date for the HW intervention not yet fixed, but due to delivery time unlikely to be performed this year

DAM nodes

  • along with first ESB rack also the DAM nodes will move to IB (instead of using 40 GbE and Extoll)

Network Federation Gateways

  • with aiming for an "all IB" solution the NFGWs will become obsolete
  • current status is
    • 2x NF-GW EDR/Extoll (1 x Fabri3, 1 x Tourmalet)
    • 2x NF-GW 40GbE/Extoll ( 1 x Fabri3, 1 x Tourmalet)
    • 2x NF-GW EDR/40GbE
    • the NF-GWs equipped with Fabri3 PCIe cards are not in operation
    • 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].
  • for more information on NAM usage and an example, please refer to NAM with TAMPI page

File Systems

please refer to the Filesystems overview

  • recent changes:
    • a new All Flash Storage Module (AFSM) is in place and provides fast work file system mounted to /work on compute nodes and login node (deepv)
      • the older System Services and Storage Module (SSSM) still serves the /usr/local file system
      • SSSM storage has been rebuilt for performance reasons
    • BeeGFS servers and clients have been updated
    • 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. See hint in the MOTD for efficient usage of the archive filesystem

System software

SW updates

  • new SLURM version has been installed: 20.11.8.
    • please use --interactive flag for interactive sessions now (see MOTD hint)
  • 2021 Easybuild stage is being set up
    • as of 2021-09-08 the default stage is 2020 (was 2019a before)
  • latest Intel oneAPI version is available in /usr/local/intel/oneapi

User management

BeeGFS Quotas

  • a quota for the BeeGFS file system (mounted to /work) has been implemented
    • no need to activate thresholds yet
