Lab move
- Lab is currently down, lots of new machines added
- New internal switch for warewulf provisioning
- Nothing working yet, will work throughout next week to bring it up
OpenBLAS
- Patch merged, new arches added, correctly identifying them
- Ad-hoc builder in https://openblas.ddns.net/
- We'll have to do something similar for FFTW, too!
D06
- Pak working on PAPI support, wants to upstream needs to find out how
- Would be good to have that for other arches, so we can enable OpenHPC packages
- Testing in the Linaro lab would help making sure of that

OpenBLAS
- Cleanup of the Arm builds, simplifying ARMv8 vs cores and adding support for more cores
- Performance improvement across the board and guaranteeing ARMv8 only holds ARMv8.0 code (not potentially v8.1 as before)
- Tested on Synquacer (A53), D03 (A57), D05 (A72), ThunderX, Amberwing (Falkor), ThunderX2, Moonshot (XGene)
- Pull request: https://github.com/xianyi/OpenBLAS/pull/1876
- Would be good for Fujitsu to test that code on Post-K
- ThunderX2 builds might actually be good for Post-K (larger caches)
- Will need to add
march=armv8.2+sve(inMakefile.arm64) to see SVE code coming out - We can later add Post-K mode when cpuinfo/cache/TLB details are public
