Minutes

• LBI-35 Ceph Upstream CI

  • Al Stone

    • Sees a great need for this in Ceph community as Ceph only officially release for platforms in CI.

    • Ceph CI resource intensive so machines would be allocated for this 100%, memory hog, >64G RAM + swap needed for build

    • Suggests utilizing cloud (Packet/AWS) would be better for this than COLO due to better resource scaling. 

    • x86 currently uses the cloud for this

    • Would we need 2 clusters (Debian/CentOS) although Ceph supports heterogeneous deployments.

    • COLO hosting is expensive compared to cloud.

  • Kevin Zhao

    • Cluster test is required for Ceph CI, this is 15-20 machines.

    • 3-5 days to run CI tests

    • Huawei have offered to Donate machines, and developer.

  • Graeme

    • 20 Machines will only leave 5U for infrastructure and be at least 8A over MAX current limit for COLO

• LBI-28 OCI Accellerator Extensions

  • Al Stone

    • Does this overlap with SmartNIC (Graeme: no, as SmartNIC is about getting SmartNIC ecosystem basics booted, this is about accellerators which may be in SmartNICs but also may be in normal servers).

• LBI-27 AI on Servers

  • Al Stone

    • Does this include tuning of libraries and tools (Paul: No this is using Libraries/tools already broguht up and tuned for ARM64)

    • Would it make sense for Linaro to distribute working software stacks (Graeme: This ties in with DCV)

• LBI-30 ASECloud

  • Al Stone

    • Who will this target?

    • Does it include container building tools?

    • Benchmarks may be tricky due to licenses and other legal issues. (SPEC license called out)

  • Li Wan

    • Will loop back with Peter to get these answered (ACTION)

• LBI-29 CDF

  • Kangkang

    • This is important as although LDCG has a lot of experience in low level it hasn't yet touched real data center software.

    • Waiting for feedback from Scott B (Services)

  • Al Stone

    • Make sure CI/CD tools work well on ARM64

    • good for other projects who can then leverage this work.

  • Larry W

    • Suggests partnering with packet for this rather than COLO (Kangkang we have already looked at AWS)

• Scheduler

  • Al Stone

    • LBI was cancelled how do we track the work in core.

  • Kangkang

    • Missed meeting as it was held on thanksgiving, plans to contact Mike to see how to proceed.

  • GG/Elsie

    • Invite Vincent to next SC to update on progress/plans?

    • Exactly like the last server scheduler work carried out by vincent

    • Looking into how to track these core tasks interesting to LDCG inside our healthchecks

• LBI Process

  • Larry

    • Query on the general process to be followed.

  • GG

    • Needs to have a good solid intro paragraph so TSC can select what to discuss quickly.

  • Kangkang

    • Needs to really be mostly complete as they do discuss down to low level.

  • GG

    • Is going to send out voting spreadhseet next week to prioritise 2-3 LBIs to fully complete, for presentation.

• AOB

  • Elsie

    • Introduce Takami Atsushi Fujitsu SC Represetative.
