MMC Installation on Mac

[Mayna Nguyen]

Hi,

I am trying to install MMC on a Macbook with an M2 Pro Chip. I followed the instructions from GitHub and I'm getting this error when I run make:

/Library/Developer/CommandLineTools/usr/lib/clang/14.0.3/include/smmintrin.h:14:2: error: "This header is only meant to be used on x86 and x64 architecture"

Is it possible to install MMC on a newer Mac or is there a quick fix for this?

Thanks,

Mayna

it is strange that I also do not see this post in my email, only found out when browsing the web based forum.

I do not have an M2 based Mac (only intel macs), but I expect it to work.

if your goal is to just use OpenCL version of mmc, you can type "make omp CC=gcc-10 CXX=g++-10 AR=g++-10", and install gcc-10 using

brew install gcc@10

you can also use gcc@11 or 12 as well. you can checkout our Github action CI script to see how we build mmc on the mac

https://github.com/fangq/mmc/blob/master/.github/workflows/build_all.yml

it is also possible to also use clang to build mmc under omp+OpenCL, but you will have to install libomp and replace all -fopenmp flag by -Xclang -fopenmp in compilation and -lomp in linking, this requires you to first install libomp

brew install libomp

brew link --force libomp

M2 processors are expected to support OpenCL, if you are able to build/run mmc on it, please let me know how its speed look like, you can run example/validation/run_tess.sh

Hi All,

I have a M1 Max MBP and I was able to build and run MMC-OpenCL following Dr. Fang's instructions. Note that the minimum version of GCC that supports Apple Silicon is gcc-11. In addition, you may want to modify this line to link libomp.a in case it is installed in a path different than /usr/local/lib/.

gcc@11 Homebrew’s package index formulae.brew.sh

Best,

Shijie

if you run `brew link --force libomp`, your libomp.a/libomp.dylib will be linked to /usr/local/lib

what's the speed of mmc looks like on M1? how does it compare to other GPUs in our lab?

never mind, just saw your screenshot - looks like it is just int he league of Intel integrated GPU, still quite far from the performance of dedicated NVIDIA/AMD GPUs - even the old GTX1080 GPU is about 10x of the speed in M1 max
