OpenBLAS
- Concerns were raised that the micro-benchmarks may not be representative of actual use
- We should look into BLAS-Tester
- During the GitHub discussion, we're leaning towards making ARMv8 the new base standard and remove A57
- This would encompass all vanilla Arm cores: A53, A57, A72 and A73
- Using minimal settings from the manuals to guess caches and pipelines
- Dynamic Arch would throw a wrench at it again, as it would go back relying on runtime CPU detection
- Arm CPU detection has not followed what Intel has done (for better or worse) but hasn't come up with anything better (or even functional)
- We can use PPTT for caches (with some work), but that doesn't help cpuid for CPU vendor/part, which needs firmware support
- Eric has suggested we find a work around until support gets better
- Adding the files to /sys by hand (via bind mount or just plain copy)
- Add to OpenHPC's recipes, perhaps the Ansible playbooks?
- Everyone was in agreements that, regardless of good cpuid support, having a solid base is crucial
