Build Conda Package for Khiops on Linux ARM64 Architecture

[lucaurelien]

Description

We already have a Conda macOS package compatible with the ARM64 architecture. However, we currently lack a Linux ARM64 version. This is important for Mac users who prefer running Khiops in a Docker container (to be based on a Linux-ARM64 image).

Justification

I conducted a performance benchmark comparing the native Conda installation of Khiops on macOS with an emulated Docker Linux-AMD64 image. The results are as follows:

• Native Conda installation on macOS ARM64: The supervised Adult.txt scenario takes approximately 3 seconds.
• Emulated Docker Linux-AMD64 image: The same scenario takes approximately 50 seconds.
  The execution time in the container may be degraded due to Docker overheads, but the inadequacy of the architecture is likely to be the main cause of performance differences.

These results show that running Khiops on a Linux-ARM64 architecture container might significantly improve performance.

Note that runners for Linux ARM are not planned in GitHub. So we either do this manually or with a self hosted runner or by cross-compiling (always a tricky ordeal).

Perhaps work started on https://github.com/KhiopsML/khiops-python/tree/cross-compile-khiops-to-arm64 could be adapted to Linux in an easier way? Worth trying perhaps?

Now that they are planned, I'd prefer to wait for the Linux ARM runners

Should we join the waitlist?
