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, -- Marten Feldtmann
Hi Marten, Currently I'm using this this vm from here http://www.mirandabanda.org/files/Cog/VM/VM.r3395/cogspurlinuxhtARM-15.26.33... 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. Le 5/7/15 21:24, Attila Magyar a écrit :

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 âlatest-spurâ 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 :) Esteban
