Situation - Raspberry PI and Pharo + Squeak

Hello,

can anyone summarize the situation of Squeak/Pharo under Raspberry PI at
the moment ?

What platform/version is working, which vm should be used and it should
be useable ... what is the difference of SPUR here etc ....

Thanks,

Hi Marten,

Currently I'm using this this vm from here

http://www.mirandabanda.org/files/Cog/VM/VM.r3395/cogspurlinuxhtARM-15.26.3395.tgz

with the latest Pharo 5 spur image from here

http://files.pharo.org/image/50/latest-spur32.zip

As far as I know, spur is a new memory manager but I'm not familiar with the details.

There is also a stack vm that works with ordinary images, but it lacks JIT compilation therefore a lot slower than cog.

This is good to know that you use the spur vm with Pharo 50.

Hi,

thanks for all these explanations. I tested the versions you mentioned
below with both Pharo and Squeak.

Squeak-GUI (4.6) seems still to be three times faster than Pharo's GUI
(5.0) - but actually it's at least a Pharo version which has an
acceptable speed.

Yes, this is a lot like that. Hard to actually compare because they diverged a lot (we adopted Polymorph, etc.) that made our UI slower. In regular machines, this is not a problem but they are some scenarios where it shows it weakness.
We are working on enhance the performance of our tools.
If you are trying a “latest-spur” image (and I suppose you do, because others do not work ;) ), you can try:

Nautilus useExperimentalFastTable: true.

is still WIP, but I would like to have some feedback :)
