Agenda 

  •  Round the table SWOT discussion

Minutes

  • Kanta : Kickoff with introduction

  • Scott Hara
    • Need a class leading server available for development
    • Need to prepare open src libraries. To tune libraries and components
    • Note the headcount in Linaro is low
    • Perhaps look into HPC Toolkit?

  • Larry

    • Issue is to have OpenHPC equivalent to x86. And challenge is micro optimization

    • Want to see open src GCC + LLVM toolchains. I'm confused with the ARM model and when their LLVM changes will go upstream. We would like to see LLVM caught up with GCC

    • Inifinband - Don't think this is a good investment for Linaro. It's niche expertise – but still required for the market

    • No GPU compute/offload solution is supported on ARM today – major gap

  • Jon

    • Concern customer adapting HPC solution. Inifiniband solutions no one is really looking into it

    • LInaro doing good job by highlighting a problem

  • Martin : We are 4# engineers working on HPC

Jon : Go for core implementation and should not go and investing much on fixing bug

  • Tianhong

    • Tianhong: port x86 libraries to ARM. Action to send a list
    • Infiniband is important. And companies like Huawei can support to linaro on this

  • Kato San

    • 5 things are needed

      • optimising Compiler for SVE

      • HW implementation not optimized for HPC

      • Need to prepare applications

      • We need gcc and LLVM compatibility needs to be included such as intrinsics and encourage application porting

      • See good openHPC ecosystem

  • Kanta

    • Porting of libraries

      • Larry

        • gcc 7, most of the things are breaking. And good if someone is looking into it. note that this is for all architectures, not just ARM – but we are seeing it first as we are pushing customers to move more quickly to GCC7

      • Kanta list of Status of libraries and

      • Renato ARM is hard on upstreaming the SVE implementation. May miss even in gcc 7
    • Compiler work: All agree that that is a priority Action: Linaro to investigate and scope work in this area. Possible Lead project which many can collaborate around
