Hello,
I'd like to do an FFT of a moderately large 3D cube, 1024^3. Looking
at the run-time of smaller arrays, this is not a problem in terms of
compute time, but the array doesn't fit in memory. So, several
questions:
1) Numerical Recipes has an out-of-memory FFT algorithm, but looking
through
In setup.py, svn_revision(), there is a line:
log.warn(unrecognized .svn/entries format; skipping %s, base)
log is not defined in setup.py. I'm using svn-1.6.

I don't think so.

Maybe :)

No please don't do that; I'm afraid the Numerical Recipes book has a

Damn - this should be fixed in r6830. Maybe I should have stayed with
my solution instead of

Yes, I meant that, and no, I don't have other suggestion :(

Hi,
In any case, the OS will have to swap a lot of your data :
- if you use floats (32bits), you use 4GB for your input array
- this does not fit inside your memory
- it even fit less if you count on the fact that FFT needs a least one
array as large, so at least 8 GB.
So you should, in every
