I answer back on the list...
I think I did not compile it in the last 10 years, but A.villeret did and he use github magic to compile it on various platform.
code is here : https://github.com/ch-nry/pd_shmem
updating this file will certainly do the job for a mac arm64, but I don't have time to look at it for now: https://github.com/ch-nry/pd_shmem/blob/main/.github/workflows/build-pd-exte...

Hi Cyrille,
Sorry to bother you again, but am I correct that shmem is not available for Mac arm64?
May I be of use in compiling it for that architecture, and if so, could you point me to the code repository?
Phil

Hello Phil,
shmem have been develop for this purpose, and it still works great for this purpose...
I think you can install it from deken.

Hello everyone,
I’ve converted my old ‘polywavesynth’ to being able to spawn a new [pd~] process for its voice management, and that’s working really well. I can see the load spread to other cores for multiple synthesizers, and after working out some bugs, I’m really happy with this new capability.
I have another old synthesizer, ‘polygrainsynth’ I’d like to modify similarly. It has a large array which is displayed (and can be edited) in the top-level process. The array is used by the individual voices, which would be in a subprocess. Is there a way to share that array between the parent process and the sub-[pd~] process?
I searched the archives and found mention of ‘share-mem’ by Cyrille Henry back in 2012: https://lists.puredata.info/pipermail/pd-list/2012-11/098714.html https://lists.puredata.info/pipermail/pd-list/2012-11/098714.html <https://lists.puredata.info/pipermail/pd-list/2012-11/098714.html https://lists.puredata.info/pipermail/pd-list/2012-11/098714.html> but I can’t find any other mention of it.
Best,
Phil
