Humm. Well, it's a big array, that's for sure. But
my middling machine can handle it. Do you have a
first born son? Would you be willing to trade him
to your system administrator for more process space?
If you are going to work with big data, you pretty
much have to have decent tools, or things get
hopeless quickly.

I guess you could try reading the data in smaller
chunks, but what is the point? Eventually, you
are going to want to do something with the data
and it doesn't appear you have the memory to do it.

I think I would be thinking about getting more memory
(which is cheap) rather than thinking about complicated
workarounds.

Cheers,

David
