I downloaded the one you linked 
(http://files.pharo.org/vm/pharoS/raspbian/latest.zip 
), but it was a pre-spur 
VM, so I had to use 50496 from the "preSpur" folder.
It didn't recognize the -nodisplay parameter, so I had to open image normally 
to do tinyBenchmarks.
Performance was fairly bad compared to Cog Spur (34M bytecodes, 2M sends), and 
in general not suitable for live editing of a Pharo image at all (8 seconds to 
open a browser, etc), so if a newer does not exist, I doubt it makes sense to 
spend effort creating one that reads Spur images other than as an intellectual 
exercize with a Cog VM available.

Cheers,
Henry

That's the one I downloaded/ran Pharo on.
Like Todd said, there's also a Spur VM shipped with raspbian (as part of 
nuscratch package, located in /usr/lib/squeak/5.*).
Unless you've already uninstalled scratch/is running on an OS other than 
Raspbian, downloading a Squeak image and running the tinyBenchmarks in an image 
launched by
squeak $PathToMyImage should give a good baseline, on my machine it yields 
comparable tinyBenchmark numbers to the above Pharo build.
(In fact, it runs Pharo 6 images as well, the difference is mostly in plugins 
it seems. I guess you'll encounter errors if opening a file browser that 
attempts to use the extended FilePlugin prims, for example)

I'd recommend focusing on verifying any externally interacting parts you intend 
to use work correctly, since that's generally the area that's most spotty.
For instance, while FFI plugin ships with Pharo VM, you may (as I did on 
cursory testing with the vm linked above) get failing float/double call tests 
(60262 image), or downright crashes due to illegal instructions (latest 5.0 
image)
OSProcessPlugin shipped (externally) with the squeak cog vm has been sort of 
hit-and-miss, on above pharo vm it's built internal and seems to be working 
(but curiously, has no canonical source version from which it was generated in 
the Modules list...).

If you plan on developing on the Pi rather than just deploying to, switching to 
Bitmapped Fonts asap is a good idea; iirc the work that was done to provide 
optimized arm-assembly primitives included (bitmap) font rendering.
Disabling auto-complete and syntax-highlighting (that seem to tend to cause 
frequent noticeable pauses), and commenting out 
"write-entire-contents-to-file-every-keystroke" functionality from Playground 
code (so your SD-card doesn't die a premature death), are other small ways to 
make a less jarring experience of it.

Or, framework use allowing, you could save yourself a lot of work flow 
interruption frustration and develop using a Squeak image instead.

Cheers,
Henry

Speed is similar to what I got before 160M bytecodes/s, 11M sends/s

Maybe all the VMs that I tried before were all Cog VMs ?

Is there still a stack VM (PharoS for ARM, 5.0) ?

 Hi Henry,
 
 That is exactly the kind of reference/experience I am looking for.
 Could you please point me to the exact download URL you downloaded ?
 I will happily test it ;-)

Hi Sven, 

this vm: pharo-linux-i386.7237aa8.zip 


should work. Name is bad but is an ARMv6 VM… did you tried it?

 Are you 100% sure you benched different VM's?
 A stack VM (PharoS) getting the same results as a Spur VM 
 (cog_linux32ARMv6_pharo.cog.spur_201610142319.tar.gz) is rather 
 suspicious...
 
 At least on my Pi3, the spur Cog VM gives  numbers around 250M 
 bytecodes/160M sends
 which, while still "slow", is a decent bump in speed compared to what 
 you're seeing.

The Squeak VMs that come with raspbian seem to be of the older variant (I am 
using Pharo 5).

You known, "This interpreter (vers. 6505) cannot read image file (vers. 6521)."

Still, in order to be sure we are talking about the exact same VM, version info 
is needed.

There is a scratch on cog vm as part of the standard raspbian distro.

Have you tried that?

Hi Henry,

That is exactly the kind of reference/experience I am looking for.
Could you please point me to the exact download URL you downloaded ?
I will happily test it ;-)

Thx,

Sven

Are you 100% sure you benched different VM's?
A stack VM (PharoS) getting the same results as a Spur VM 
(cog_linux32ARMv6_pharo.cog.spur_201610142319.tar.gz) is rather suspicious...

At least on my Pi3, the spur Cog VM gives  numbers around 250M bytecodes/160M 
sends
which, while still "slow", is a decent bump in speed compared to what you're 
seeing.

Cheers,
Henry

[Pharo-users] Cog VM on Raspberry Pi ?

[Sven Van Caekenberghe]

Hi,

Does a (faster) Cog VM for the Raspberry Pi actually exist ?

I tried comparing the latest OpenSmalltalk VM with some older ones, only to 
find that they are all equally fast (slow actually):

pi@raspberrypi ~/Pharo $ ./pharo -nodisplay Pharo.image printVersion
[version] 5.0 #50581

"http://files.pharo.org/vm/pharoS/raspbian/latest.zip;

pi@raspberrypi ~/Pharo $ ./pharo -nodisplay Pharo.image eval '1 tinyBenchmarks'
'167429692 bytecodes/sec; 11160247 sends/sec'

"http://www.mirandabanda.org/files/Cog/VM/VM.r3427/cogspurlinuxhtARM-15.33.3427.tgz;

pi@raspberrypi ~/Pharo $ ./products/phcogspurlinuxhtRPi/pharo -nodisplay 
Pharo.image eval '1 tinyBenchmarks'
'166992824 bytecodes/sec; 11337746 sends/sec'

"https://bintray.com/opensmalltalk/vm/download_file?file_path=cog_linux32ARMv6_pharo.cog.spur_201610142319.tar.gz;

pi@raspberrypi ~/Pharo $ ./products/phcogspurlinuxhtRPi/pharo -nodisplay 
Pharo.image eval '1 tinyBenchmarks'
'166992824 bytecodes/sec; 11337746 sends/sec'

That is no significant difference on a RPi 3, at all. Is this normal ? Am I 
missing something ?

Thx,

Sven
