Re: [Pharo-project] Memory usage

by David T. Lewis

I don't know of anyone who has built a StackVM for the 64-bit object memory, so this might require some development work. It would certainly be possible to do it, but I don't think that anyone has tried. Note that Eliot has plans for improved object memory formats, and the current 64-bit object memory is a "simplest thing that could possible work" conversion of the 32-bit object memory. I expect that Eliot would want to put his energy into the new object memory format(s), so a StackVM for the current 64-bit object memory would probably require someone to volunteer to do some development work.

Hi guys, I've been building the iOS StackVM for my own uses and am definitely interested in getting a 64-bit StackVM for some large data sets I'd like to load in RAM for some experiments.

Re: [Pharo-project] Memory usage

Hi Jannik, I am not a Mac user, and I have only ever done this on Linux, so I cannot promise that it will be easy. Possibly Esteban can give us some advice here, and correct my errors. Also, if you are going to try this, we may want to take the discussion to the vm-dev list. You will need to install the Mac tools for compiling Unix programs (sorry I do not know what this is called) and you will need to be able to compile programs using CMake and the gcc tools on a Mac. I know very little about this myself, but I'm sure others can give some tips. The actual VM that you will need to build will be an interpreter VM, and you will be building it with a preprocessor macro set to force use of the 64-bit object format. The resulting VM will be slow compared to what you are used to with Cog, and it may not have all the features that you would expect from a Mac VM (i.e. the VM that Esteban supports), but I expect that it should work on Mac and that it would allow you to run a 64-bit image prepared with the SystemTracer. As luck would have it, Ian Piumarta is in the process of updating the unix VM code right now, and this will make it easier to do the build for 64-bit images. I would say that we should wait a couple of days before starting any new work on this so that we have all of the latest updates. I'm not sure if this is something that you want to get into, and it is not what I would call "easy" ;) But if you want to try it I will do my best to step you through the process.
