Michael Smith commented on IMPALA-12118:
----------------------------------------
With LLVM 5,
https://github.com/aws/aws-graviton-getting-started/blob/main/c-c++.md suggests
using {{cortex-a72}} for compatibility.
> Consider using pytorch cpuinfo library for CPU detection / logging

> Key: IMPALA-12118
> URL: https://issues.apache.org/jira/browse/IMPALA-12118
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 4.3.0
> Reporter: Joe McDonnell
> Priority: Major
> Labels: arm
>
> The code in be/src/util/cpu-info.h/.cc provides information about the CPU
> that we run on, along with NUMA configurations, cache sizes, etc.
> Pytorch's cpuinfo package seems to cover most of what we want to do across a
> much broader set of processors / architectures. It has a compatible license.
> See [https://github.com/pytorch/cpuinfo]
> We should see if this is useful for our cpu detection code.
