Apple Arm Chip Support

[huizhen]

Hi developers

I am a fresh user of oneMKL. I am working on Mac OS platform. And I have a question: Does this library currently support the Mac Arm architecture? Or how can I get an arm-based oneMKL library? Thanks!

Hi Huizhenshi,

Thanks for posting on Intel Communities.

Does this library currently support the Mac Arm architecture?

>>Please refer to the below link for details related to oneMKL system compatibility.

 I noticed there is no mentioned Apple Dev IDE XCode. So is it not being supported?

If you look in that document under Supported Hardware Platforms / CPU you see that only Intel CPUs are supported.

Hi Huizhenshi,

As per the system requirements mentioned in an earlier thread, we regret to inform you that the architecture mentioned is not supported as of now.

So is there a plan to support the Arm-based MKL library by intel? Or If building an Arm-based MKL library with source code (https://github.com/oneapi-src/oneMKL), are there any potential problems here?

Hi Huizhenshi,

We are discussing your issue internally. We will get back to you soon with an update.

Hi Huizhen shi,

Is there a plan to support the Arm-based MKL library by intel?

>>At the moment there are no plans to add support for Apple's ARM-based processors.

In addition, There is a difference between oneMKL Interfaces/the GitHub repo and Intel oneMKL that was pointed out.

Intel oneMKL Interfaces/the GitHub repo is a wrapper library around several backends like cuBLAS for Nvidia, etc. The user is free to modify the source code to add an Apple backend (using, e.g., Apple Accelerate) The wrapper library uses Intel oneMKL on Intel platforms.

Intel oneMKL is Intel's implementation for Intel CPUs and GPUs.

 Actually, it does not tune for Intel only It supports AMD now too offically with tuning for it. As for ARM, SVE2 is being merged in libxsmm, that is a key component of OneMKL.

I'd like to correct this: LIBXSMM does not belong to OneMKL and is not even a part of oneAPI. It's a separate project. It supports ARM indeed but this fact is not related to oneMKL support on Mac/ARM.
