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:
- Not asking for distros to pick this up
- Lustre is a well established setup that needs supporting
- We need to agree what that 'something' is which we support for Arm
- 1. Collate information on what labs are using. Need to collate as a sig
- 17/4/18 KV: In progress, working on a Google Doc to share out
- 15/5/18 Google spreadsheet created for all to use
- 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
