Re: Handling a 450,000x450,000 array with Perl

Hi.

Thank you very much for your quick answers. I try to handle data from a
450x450 meter surface.

I've got 100,000 elements distributed on this surface, and each
square millimeter can hold one or more elements. So the array to create
is a sparse one: most of square millimeters holds zero elements, and
the rest, 20 or less.

I'm trying to find the square meter with more elements inside.

Thank you very much.

Hi.

I'd like to create a program to handle data (natural numbers)
within a 450,000 x 450,000 array. I'm considering Perl, but
I don't know is it's powerful enough to manage it.Perl is, but you'll find few computers that could store 202 billion
"natural numbers".
Remember, a PC has a RAM of around 2 billion bytes, give or take a few.
You could hold a maximum of 16 billion natural numbers as long as they
are 0 or 1. But, 16 billion is still not 202 billion.

In any case, this will be a system where native integers have 64 bits.
