Mac Native M1 (arm64) support?

[dstranathan]

What is the status of Mac Native M1 (arm64) CPU support?

[psobolewskiPhD]

I've had success with Fiji, by downloading with no JRE and using a native JRE (e.g. Azul). Works very well, nice speed up ~40% on a CPU computational task. Some plugins that use compiled libs, etc. may need tweaks. For example getting native CLIJ working resulted in an 8-fold speedup over Rosetta. You can see some of my experience in this twitter thread: https://twitter.com/psobolewskiPhD/status/1342494593082920960?s=20

@psobolewskiPhD JogAmp 2.4.0 (JOGL, JOCL, JOAL, Gluegen) was released earlier this month, and the release includes builds for mac-arm64. I should have new releases of imagej2 and fiji by the end of the week that include this release. This will be a big step toward ImageJ2 and Fiji supporting Mac M1 more comprehensively.

Cool, @ctrueden I'm happy to help test, though I'm not sure I've used those elements much previously (as I've been using Fiji with native arm64 JRE for a long time now)

@psobolewskiPhD I'm guessing that your current Fiji setup cannot use the 3D Viewer plugin. One easy way to test that is to do:

• File > Open Samples > T1 Head
• Image > Type > 8-bit
• Plugins > 3D Viewer

And see what happens.

My hope is that with the new JOGL 2.4.0, this will either begin working automatically, or else maybe with some small tweak somewhere.

Correct:

Sounds good!
