I'm writing a Cocoa app (10.4.6, Xcode 2.2, PM 2xG5 2GHz, 8GB), and I'm
loading large tensor matrices, 1.1 GB each. The problem is that I can only
load one, the second one crashes the app with malloc complaining "cannot
allocate memory". I've verified in gdb that the size I'm requesting is
correct.
Base VM of the app is 380 MB. After loading one of the tensor matrices, it
goes up to 1.48 GB. But why should loading the next 1.1 GB tensor matrix
cause the app to blow? Adding the next one should only bring it up to 2.58
GB (Safari currently is sitting at 2.66 GB). Don't I have 4 GB (or
thereabouts) of VM available to the app? Do the new Intel machines have a
64-bit VM address space?
