I'm running a MacBookAir M1 and it feels the same: not really faster, just
quiet and cool. But this is just blabla.. Is there a benchmark.scad I
could measure the time ?

Hi,

This topic is the reason I joined this list.

I have done some testing with complex objects to look at both the initial display time and the rendering time. All of what I have done is based on what OpenSCAD reports.

Some of what you are seeing here might be based on the released version running under emulation. I have managed to compile a native M1 version using whatever is on GitHub for comparison.

When initially loading an object, the emulated 2021.01 version seems to be faster than the native version at displaying the preview. This doesn’t make any sense. I think there might be some debugging code getting in the way.

The native version is quite a bit faster when rendering. Rendering an object that takes 3 minutes in 2021.01 under emulation might take less than two minutes when OpenSCAD is native M1.

As a third test, I tried this under ARM version of Ubuntu 20.04 using the VMWare Preview. The Ubuntu version I have is 2019.05. It is the fastest of the bunch both for generating a preview and rendering. The Ubuntu version is faster by a significant amount.

I am using an M1 Max powered MacBook Pro. I also have an M1 Mac Mini available. I haven’t done any comparisons yet between the Mini and the MacBook Pro. I also have an Intel i9 MacBook Pro that I will use for some quick testing.

My native build uses libraries installed by HomeBrew. I haven’t had a chance yet to dig in and see if there are any compiler options or debugging flags that might be slowing things down.

Clarification? All three of those are running on the MBP M1Max? The third one booted into Ubuntu rather than MacOS?

I have to say that I was surprised: the M1 actually felt faster to me, even though OpenSCAD says the M1 is slower.

I'm running a MacBookAir M1 and it feels the same: not really faster, just quiet and cool. But this is just blabla.. Is there a benchmark.scad I could measure the time ?

Thanks. I’ll take a look at this. For now, I would like to get the single-core build working like it should, or at least understand why the native linux build is so much faster. At least that way whatever is causing the slowdown doesn’t get lost in any multi-core improvements.

I did my native build using HomeBrew for all of the dependencies and then manually compiled the OpenSCAD source. That worked pretty well with whatever is current on GitHub. I ran into errors when checking out the 2021.01 release. Now I’m going back and manually building all of the dependencies.

Thanks. I’ll take a look at this. For now, I would like to get the single-core build working like it should, or at least understand why the native linux build is so much faster. At least that way whatever is causing the slowdown doesn’t get lost in any multi-core improvements. I did my native build using HomeBrew for all of the dependencies and then manually compiled the OpenSCAD source. That worked pretty well with whatever is current on GitHub. I ran into errors when checking out the 2021.01 release. Now I’m going back and manually building all of the dependencies. > On Nov 14, 2021, at 4:58 PM, David Phillip Oster <davidphilliposter@gmail.com> wrote: > > If you are going to recompile OpenSCAD from source, here are my notes on attempts to add GPU and multi-core support to OpenSCAD: > > https://github.com/openscad/openscad/pull/3193 <https://github.com/openscad/openscad/pull/3193> > https://github.com/TheJKM/OpenSCAD-Parallel-Build <https://github.com/TheJKM/OpenSCAD-Parallel-Build> > https://www.reddit.com/r/openscad/comments/k790b4/multithreaded_bounty/ <https://www.reddit.com/r/openscad/comments/k790b4/multithreaded_bounty/> > > On Sun, Nov 14, 2021 at 12:36 PM David Schooley <dcschooley@gmail.com <mailto:dcschooley@gmail.com>> wrote: > Yes.

I’ve got the 24 core M1 Max, upgraded from a 2013 13” i7. Between the new processor and turning on some of the experimental features in the nightly builds, one project I tested that used to take over 30 minutes to render now finishes in under 30 seconds. There’s no frame counter on the 3D display, but the most complicated stuff I’ve tried seems to be running at about twice the frame rate that I got with a cube on the old machine. Can’t wait until there’s an M1 native build...

Anyone here running OpenSCAD on an M1, M1 Pro or M1 Max yet?

I have an Intel Mac Mini and the 2 pain points are F6 rendering and then moving around in a complicated rendered display.

Due to the non-multithreading, the gains might not be what I would hope, at least on the first item. Perhaps hoping for better not he second.

I'd like a OpenSCAD compute service running in the cloud. Is this already available?
