Try running that VM with one of your images. If it runs and gives you some sort of error message about not understanding the image format, that's good! That means all you need to do is trace your image to 64-bit object format, which should be fairly easy to do. Dave

Re: [Pharo-project] Memory usage

Hi John, There is no regression in the interpreter VM ... well actually there was about 6 months back, but I keep an eye on it and it's fixed again now :) The 32-bit interpreter VM will not fail on any 2GB or 4BG boundaries, and an interpreter VM compiled for the 64-bit object format can handle images greater than 7GB (probably much more, but my 8GB PC is too small to do anything larger). I'm not sure if all of the necessary fixes are in place for the StackVM and Cog. If not, I'm sure it will be addressed over time (it's just not something that I have ever checked). I believe that Jannik is interested in running very large images, at least on an experimental basis. For anything over a few GB, this requires an interpreter VM and a 64-bit image. As you know, this is sure to run into problems for the garbage collector as the number of objects increases, but it would certainly be interesting to see how far the current garbage collector can go in real world conditions before it turns to mollasses.

One should actually unify the changes before applying them. - try removing duplicate changes - warn if there are duplicate entries and if I'm already in the mood: - show recategorizations as proper changes best cami
