Infiniband installation on OpenHPC tracking on HPC-351:

  • Code mostly finished, will test next week
  • Will submit a pull request once finished

We need to move the repository to Linaro, Fujitsu forks, we all send pull requests to

  • Pulls requested will be merged on master, but we still keep the production branch for our lab
  • Fujitsu should slowly review our own changes, so that we can merge them to master, too
  • We can still keep separate branches for each lab, so that we can slowly review each other's patches

LLVM development on track

  • GVN ad pipeliners done, no tests yet but rebased to trunk
  • regalloc still working, still on LLVM 6
  • There was a round table at LLVM dev meeting about pipeliner
  • We sent our work to them, but not yet got feedback on discussions
  • GitHub's monorepo move should not affect those changes, we'll move when they're done

Finishing the cleanup of the lab

  • Mr-Provisioner client is upstream
  • Removing the old Ansible client from our lab (almost finished)
  • Adding an Infiniband automated test in Jenkins

Working on ERP for next release

  • Tested on our machines, kernel 4.18, working well
  • Some backports coming, we'll test again

Will look into OpenHPC test suite next week

  • Fix long/short run issues
  • understand why tests all run n 0s
  • add missing tests

Looked at OpenBLAS performance

Arm claims improvements on their Fortran support (commercial compiler)

  • None of this is upstream, so we have no idea what's going on
  • Fujitsu has to use their own old compiler or gfortran
  • Our work is independent of language
  • F18 is a new Fortran compiler for LLVM written in C++17 (sounds promising)
