Pharo (cog) Vm on Windows with 2GB virtual mem

oscar
Hi Guys,

   I read in this thread


 that 512 mb limit can be avoided in windows, but a re-compilation is needed. I was wondering if the situation changed, and now we can pass a parameter. Otherwise, I would be interested if any of you has a pre-compiled vm with more mem.

I need to run some experiments and I need 2GB (or 1.5 GB at least ) on a cog VM for Windows.  

Thanks in advance.

I think latest Pharo VM supports to change the memory limit by only changing an ini file. Igor did that not long ago.

Cheers,
Guille

Thanks, but what would be the parameter?

 

This is the default .ini

 

[Global]

DeferUpdate=1

ShowConsole=0

DynamicConsole=1

ReduceCPUUsage=1

ReduceCPUInBackground=0

3ButtonMouse=0

1ButtonMouse=0

UseDirectSound=1

PriorityBoost=1

B3DXUsesOpenGL=0

CaseSensitiveFileMode=0

 

 

So there is no mention the paratemer to change or add.

 

Cheers.

I can only guess by the comment in the commit:


Can you check that?

Talking about GBs it makes me wonder , even if the image allowed more than 500MBs if that would be a wise move.

Smalltalk is afterall one of the slowest , execution wise, programming languages. In python which is as slow if not slower, the attitude is to move big data to C libs and then interface with these C libs via python.

When I see even morphic at times take up to 50% of my dual core 2.0GHz CPU just makes me wonder if cramming 1 GB or more inside the image will end bringing pharo to a crawl for processing that data.

So what pharo may need is something that already nativeboost is doing, mapping to C types and access to fast C functions for processing and manipulating big data. Just make it more easier.

For example python has numpy (mainly C code, extra types etc) and nowdays also Blaze is emerging as a future candidate.

https://github.com/ContinuumIO/blaze

just a thought.

Thanks a lot, I added

 

AddressSpaceLimit = 2147483648

 

To the .ini file and all is working smoothly.

 

FYI, I don’t have speed problems with such memory. Of course, If I’ll process some big data, I’ll wait a while to get the answer, but the same happens in any other lang/platt. Certainty, I can do fast experiments in C, but I don’t get all Pharo benefits, like pausing my analysis and resuming it later, such thing in C (or may be any other language) would require to store the intermediate data into files or a database. With Pharo, I don’t care about that.

 

Cheers.

That's a great quote for marketing Pharo. Thanks Oscar.

Hi,

As far as I can tell, you should set the limit in MBytes.

So, for 2G, you should have:
AddressSpaceLimit=2048

I am using 1GB for some Moose analyses. I benchmarked and got no sign of slowdown.

Cheers,
Doru

thats great indeed. I would be interested to hear your experience with it when you start processing that data , maybe hint* *hint* a blog post ? :D

It benefits pharo in general to have practical examples that show that pharo can be a very efficient environment and language.
