Re: Most efficient way to write a large matrix to disk

Hi!

Without any intent of being rude (this is a serious consideration):
when you're handling such large matrices,
isn't it time to ask yourself the question: "Are all the data that I
want to store still meaningful?"

Hi,
unfortunately the answer is "yes" as these data
are intermediate for computing other quantities.
In my particular case, they are the nuclear-motion
wave functions for a triatomic molecule.
What is stored are the values of
each wave function on a 3D grid.
A typical grid is about 100x100x50 (in some coordinate
system) while the number of wave functions (states)
is of the order of 500-1000, so it's not too difficult
to get a huge number of values.
The wave functions are needed later
to calculate transition intensities and other quantities.
