Good morning,I have installed openFoam v9 on my new macbook pro 13 with SoC M1 and 16 Gb RAM via docker. However, the performances are disappointing.
I did some tests with some tutorials and with a personal project (interFoam), and the comparisons with an i7 6700 (Desktop) with window 10 are very disappointing.

The intel processor is much faster.

I was wondering if this is due to the fact of using Docker on Mac or depends on the fact that the M1, being arm, is not yet supported natively, therefore the performance is lower?

To be honest, I have read that docker is now natively supported on M1...

Also, is it possible to install openFoam on Mac Os natively, without Docker?

Thanks to all.

Miguel.

Dear Miguel,

I am wondering about the same.

Information on how to install older version of OpenFoam from source on older version of MacOS is listed here http://openfoamwiki.net/index.php/In...6-ext#OpenFOAM .

I imagine that much (but certainly not all) does carry over to newer
version of OpenFoam on MacOS-Big-Sur in M1 (e.g. Xcode and gcc run fine on M1).

I am happy to join a small group to explore details.

Buena suerte y saludos, Domenico.

Hi Domenico, thank you for your replay...

To be honest I’m not able to compile from source code in my MacBook Pro M1.

I’ve tried some guides (similar to the link you reported) but whithout success...

Can anyone provide a guide or some tips to compile in Mac OS from source code? Thank you...

Miguel, our users have tested this M1 CPU, also on virtual machine. From our standard test case, m1 needs 359s to run with 4 cores, which is almost identical with 2680V2 or even 7742 (337s), of course 4 cores. Since this user also use virtual machine, so I think the problem does not come from the OS.

For more information of different CPUs, please check it here (Chinese though, maybe you can translate them by google)

Thank you for your reply... in virtual machine, do you mean that your test was running using docker?

I’ve tried weirOverflow tutorial on my MacBook Pro m1 (docker) and on my desktop Intel i7 (6700) - Ubuntu 21.04. MacBook took 1572 sec to run the simulation, the desktop pc 160 sec!!!!

not sure. That user said its on virtual machine, but I have no idea what kind of virtual machine. but shouldn't be docker.

These are the results if you run my test case. https://www.jianguoyun.com/p/DeabU1wQ9s3ZBhjc7LgD
