HI all, does anyone know the status of Racket on Raspberry Pi?

@mark.warren it works.

Let me know if I can provide further help.

@pocmatos Cool, can I just apt-get it or is there a distribution somewhere?

apt-get it should work. You can also compile it from scratch.

@pocmatos Thanks, I’ll give it a go later (just got a new 8Gb Pi 4 and I want to give it a workout)

Should work great. I have been testing them on rpi3 and rpi4s with both 2 and 4 Gb.

If you have aarch64 on the rpi4, you won’t have a jit btw.

but it still works great.

I’m just using the latest PiOS

32bits?

Yep

ok

Would Ubuntu be better

OS doesn’t really matter here.

Just meant that you can get 64 bit Ubuntu if that would be better

@pocmatos Ok, apt-get gets 7.2 (which is fine) but can I get a later version?

@mark.warren you might have to compile it yourself.

I am happy to create one distribution of racket 7.7 for you, if you want.

I don’t want to put you to any trouble, I’ll give compiling myself a go. I ought to learn how to do it. In the mean time 7.2 is quite enough to keep me going. Thanks for all the help.

Sure.

Let me know if you run into troubles compiling it.

Cheers

If Ubuntu’s apt-get works fine, wouldn’t the PPA work too?

I haven’t tried Ubuntu, I’m just using Raspbian at the moment.

Thanks for helping out @mark.warren - next time, moving the conversation to a thread might be helpful :)

@badkins Sorry, I don’t know about threads. I’ll check it out. Cheers

No problem @mark.warren - I was mainly directing that toward @pocmatos. Once the first person replies in a thread, it’s easy to continue the conversation in a thread. In other words, you can’t start in a thread, but you can reply in a thread to start the thread :slightly_smiling_face:

Not a big deal, it just cleans up the main channel.

Ok, I’ll remember that for the future, thanks for the info.

As of version v7.7.0.7 (starting with snapshot 20200601), Racket CS locally unboxes floating-point arithmetic. That change speeds up single-process mandelbrot by about a factor of 2, but by avoiding allocation, it speeds up mandelbrot with futures by a factor of 10 or so — which means that Racket BC and CS now run the mandelbrot benchmark from the game at about the same speed.
