sage 9.3 now available on Apple silicon through conda

[Isuru Fernando]

To get a native conda on Apple silicon, run the following

    curl -L -O https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-$(uname)-$(uname -m).sh
    bash Mambaforge-$(uname)-$(uname -m).sh

Start a new session and then you can create a new environment with sage,

    mamba create -n sage sage python=3.9

This is largely untested as all the dependencies were cross compiled from macos-x86_64 to macos-arm64

except for NTL and pari which had to be compiled natively.

Let me know how it goes. You can run the tests by doing,

    mamba install conda-build -n base

    conda build -t ~/mambaforge/pkgs/<path-to-sage-conda-tarball>

Is there anyone with a M1 Mac who can test this out? It'd be great to see how much of sage works.

I have an M1 Macbook Pro. I just tried this out and:

(1) your install instruction process did not confuse me at all
(despite me never installing mamba before), and everything went
perfectly,

(2) Sage starts up fine and all the random "old favorite" commands I
tried worked fine.

(3) It's fast for the first thing I tried! Here's a little benchmark:

sage: a = random_matrix(GF(7),10000)
sage: %time b=a*a
CPU times: user 1min 2s, sys: 3.99 s, total: 1min 6s
Wall time: 10.9 s

vs my random remote intel server:

sage: a = random_matrix(GF(7),10000)
sage: %time b=a*a
....:
CPU times: user 18.8 s, sys: 543 ms, total: 19.3 s
Wall time: 22 s

But then strangely the next thing I tried it was WAY slower than my
remote Intel server:

# M1
sage: %time ModularSymbols(2*997, sign=1).fcp(3)
Wall time: 12.5 s

# Intel server
sage: %time ModularSymbols(2*997, sign=1).fcp(3)
Wall time: 753 ms

Wow, the M1 gets killed by an order of magnitude..
Both benchmarks involve linear algebra -- though different libraries
-- so I wonder if cross compilation messes that up.

Other things like 2d plots pop up just fine.

In any case, excellent work and many, many thanks!

I'll run the full test suite and report back.

I don't know how to run the test suite.

Hi William,

Thanks for checking this.

remote Intel server:

That is strange. If you can track this down to which spkg is responsible, I can have a look.

> I don't know how to run the test suite.

Thanks. That error message is useful. I'll fix it and let you know.
