Maximum Variable Size in Octave

[Przemek Klosowski]

Sorry, I didn't need to do IO on large arrays. Since on most systems
the effective disk speed is on the order of 10MB/s, I/O to a 10GB
array takes half an hour. The best way to say it is 'disk is the new
tape'; you don't store unless you really need to; calculate in memory
as much as you can---in most cases the initial conditions and outputs
are much smaller than the intermediate data. 

Still, arguably, Octave is not 64-bit ready because of I/O.
