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

• 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
