PyAF support for ARM64 Architecture #187

antoinecarme · 2022-03-09T22:01:21Z

Check PyAF ARM64 support. This can be seen as a software robustness/portability test for PyAF.

Need to run all PyAF tests on a Debian Linux ARM64 on an AWS machine and/or an SBC.

Check that all needed data packages are available (point missing packages).
Run build tests (make -f tests/Makefilebuild-tests), circle-ci equivalent
Run extended tests (make -f tests/Makefile all)
Analyze numerical differences if any.
Reconfigure Cicle-CI to run tests for this hardware architecture on every commit.
Parallel hardware performance ?

Target Release : 2022-07-14

https://aws.amazon.com/fr/ec2/instance-types/c7g/

Amazon EC2 C7g instances, powered by the latest generation AWS Graviton3 processors, provide the best price performance in Amazon EC2 for compute-intensive workloads. C7g instances are ideal for high performance computing (HPC), batch processing, electronic design automation (EDA), gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad-serving. They offer up to 25% better performance over the sixth generation AWS Graviton2-based C6g instances. C7g instances are the first in the cloud to feature DDR5 memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory.

AWS missed our Rendez-vous. ARM64 instances are in preview mode only (a lot of web forms ;).

Using Oracle Cloud with Ampere A1 compute instance (Free Tier). Ubuntu instances. No Debian, but will install/force debian packages anyway.

Oracle cloud has ARM64 ubuntu instances (some danger here, I use debian packages ;)
