I am trying to use Moose to do run graph algorithms on data with about 300,000 nodes. This data is map data downloaded from OpenStreetMap, and I am trying to analyze it with the Moose-Analysis-Graphs package. However, it seems completely unable to handle this, partially due to unoptimized algorithms, but mostly due to memory limits of the VM or image itself.

I am using the vm and image of the moose one-click image for mac: http://www.moosetechnology.org/#install . I believe this is a pharo vm and image, I don��t know if pharo and squeak are still different these days, or if it matters. Been out of squeak for a few years

This platform is seemingly unable to use more than about 500Mb of memory. I watch it in mac��s activity monitor. Once it reaches about 450Mb as measured by activity monitor, it is spending nearly all it��s time in the garbage collector, (as measured by activity monitor��s Sample Process tool). The most I��ve seen it eventually reach is 556Mb, after about an hour, then it does a hard VM crash (Pharo has quit unexpectedly).

Is there a way to remedy this? I tried running the image in 4 alternative VM��s:

- The latest pharo mac vm from http://files.pharo.org/vm/pharo/mac/ . Same issue as above. likely the same vm

- Cocoa Cog vm from http://squeakvm.org/mac/ : crashed at startup. could not load image

- Cocoa Stack vm from http://squeakvm.org/mac/ : crashed at startup; could not load image

- Carbon Stack vm from http://squeakvm.org/mac/ : refused to start

Is it possible to allocate more than 500Mb of memory to squeak?
