Sshah, What do you get if you run file *.oct on any of the files installed by the parallel package? For example, on my Intel machine (running MacPorts) I get marius$ file /opt/local/lib/octave/packages/parallel-4.0.1/x86_64-apple-darwin18.7.0-api-v55/fsave.oct /opt/local/lib/octave/packages/parallel-4.0.1/x86_64-apple-darwin18.7.0-api-v55/fsave.oct: Mach-O 64-bit bundle x86_64 You should get a bundle for arm64, as I do on my M1 Mac mini: % file /opt/local/lib/octave/packages/parallel-4.0.1/aarch64-apple-darwin20.3.0-api-v55/fsave.oct /opt/local/lib/octave/packages/parallel-4.0.1/aarch64-apple-darwin20.3.0-api-v55/fsave.oct: Mach-O 64-bit bundle arm64 If you get a x86_64 bundle, it would run a lot slower due to Rosetta. > On Mar 23, 2021, at 12:41 AM, sshah <[email protected]> wrote: > > I find that on my machine (Mac mini M1), parallel 4.0.1 runs 3 x slower than > parallel 4.0.0.
