buy more ram
A LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT more ram!
I tried to render 1920x1080 image and it takes about 50GB of RAM (using cpu backend).
with cuDNN and Adam you should be able to fit 1920x1080 in 12GB of GPU memory.

@jcjohnson do you think that is feasible to implement a trade off between time vs RAM. Using something like a memory map using SSD ?
That is not easy to implement; it would also seriously degrade performance. I've written more details in other issues.

Likewise, if one prefers L-BFGS, using nin-imagenet-conv instead of VGG19 produces 1920x1440 in 10GB (measured using CPU here).

@htoyryla How long does that take for 1000 iterations? :grin:

1 hour 40 minutes, on an i7 3.6 GHz 8 threads.

Does increasing RAM help in gpu mode too or only cpu?
More system memory will not help in GPU mode.
It would be good to centralize these user reported benchmarks
@htoyryla how do the results of nin-imagenet-conv look vs VGG19?
I find them useful enough. Difficult to compare when a) I cannot get images this large with VGG19 b) results with identical parameters on different models are not directly comparable.
Have a look here http://liipetti.net/erratic/tests/1920px-tests/
Since I made those tests, @ProGamerGov has reported that a lower tv_weight can produce sharper images with NIN (without adding too much noise that is). And I would not recommend using the highest conv layers with NIN, at least not without understanding what they contribute, see https://github.com/jcjohnson/neural-style/issues/226 .
my setup is crashing anything beyond about 600 pixels. id like to get as high of a resolution as possible. any tips for make something closer to 2k?
