Upon further inspection I have found that Octave does seem to have a
file size limit of 2GB.
....
I got the following error while running one of my scripts:
File size limit exceeded
And the file was exactly 2GB. This happens on both ext3 and FAT32
filesystems. I am running a 2.4.21 kernel.
Ah, but that is a separate issue: currently, octave internally can only
handle a 2GB single object, because it uses int pointers. That is why
I said that there should be no limit if octave makes individual, small reads
and writes to a file---what you are doing is probably reading into
a single array.
BTW, you will be in a world of pain if you are trying to manipulate
2GB+ memory objects on a 32-bit architecture such as x86. Octave may
need a fix, but you do need to run octave on a platform such as MIPS,
SPARC, Itanium, or AMD x86-64. Since MIPS, SPARC, Itanium are either
outrageously expensive, or low performance, or both, AMD Opteron class
64-bit CPUs are basically your only choice.
