Agenda 


  • Quick Reminder

    • QEMU patches upstream, please test, verify, ACK

  • Filesystems: GPFS, Lustre

  • Growing Engineering in the SIG

    • Incentivising participation and collaboration

  • AOB


Minutes

Filesystems

  • Larry: Filesystems in Arm are not currently discussed. GPFS is an IBM closed offering. Lustre is a leading HPC filesystem. Would like Renato to ensure that the OpenHPC Lustre client is validated on Arm and at parity with other architectures.
  • Lustre
    • Has a strong influence by Intel. 
    • We need to understand its scoping for Arm and where we can influence
    • Oakridge working on CI/CD upstream of Lustre
    • Lustre user Group April 23rd Argon. Who is participating?
      • 17/4/18 Andrew Wafaa and Rich Hemwood will attend and report back
      • 15/5/18 Andy sent a summary email on 2nd May
  • Lustre Server
    • Likely a bigger issue
    • There are risks around the underlying filesystem (ZFS, BeeGFS uses ZFS)
  • Lustre Client
    • Start here on OpenHPC
    • OpenHPC has a Luster server in TACC, which currently runs for Intel and not Arm
  • Other notes
    • Ceph is replacing NFS
    • Fujitsu: Testing with NFS
    • RedHat: Don't support Lustre and have zero interest. Lustre == Oakridge. We should focus on what the HPC labs find as important 
    • CephFS works just as well as Lustre
    • Cavium: 
      1. Not asking for distros to pick this up
      2. Lustre is a well established setup that needs supporting
      3. We need to agree what that 'something' is which we support for Arm
    • 2. If Lustre is the way to go then run Lustre Client on OpenHPC to identify scale of issues
      • 17/4/18 Best to do this once we have feedback from Lustre user group and Labs. All agreed


Growing Engineering in the SIG

  • Compiler optimisation lead project needs staffing
  • Reference Implementation discussion
    • RedHat compatible RPM for openHPC
  • Continue Joint marketing and business development. Key targets this year
    • ISC18
    • SC18
  • Key messages
    • Engineering collaboration
    • Business Development, e.g. getting labs and others to join the SIG and collaborate 
    • Marketing
  • Thank you to Fujitsu, Cavium, Arm and RedHat for putting themselves forward. I (Kanta) will be working closely with you to make this happen firstly for ISC18 in Frankfurt
