So has anyone tried the new 680 card?

I see the results but I don't believe it... can they fix this with better drivers or is it fubar from a hardware perspective in relations to compute capabilities?

Well what it looks like is Nvidia is crippling the gaming cards in the Computational calculations in their drivers... One reason sell more Quadro and Tesla cards. I think its the most stupid move on their behalf.

If that is true, about it being software, as in on the driver side. Then there is allways a change of someone making hacked drivers. Like these. http://www.omegadrivers.net/

Sadly the guy behind the drivers can not keep developing, due to the recession.

Well if this is all true it might be worth just to get another GTX 580 and have two of them.

I need CUDA for other projects so AMD is a no go for now at least.

Memory use on 18Mpix photos as i remember:
LOW - 168 MB
Medium - 390 MB
HIGH - 950 MB
so a ultra will use much more memory, that mean a lot of RAM - CPU - GPU - GPU mem transfers. best app for that  http://www.ozone3d.net/gpushark/ and set detailed info...... Could test it someone

Seems like I am getting a Max of about 800MB on the GPU when using ULTRA with 21Mpix images. So its not even getting close.

General / Disable Core for GPU

« on: March 12, 2012, 01:35:55 AM »

I have been wondering if you have a CPU with hyper threading do you disable 1 or 2 cores in Photoscan, due to Hyper threading being virtual core.

So for example if you have the i7 3930K it has 6+6 "cores" thats how Photoscan sees it.

I got a GTX 580 and I was wondering if I should disable 1 or 2 cores in Photoscan. Is there a thread enough to feed the GPU or does it need the whole real core for itself.

Just a little question on the side, I have been wondering regarding using full res images for reconstruction if that is indeed needed, or there to say getting the best results.

Reason I am bringing this up is regarding the bayer sensor as pixel at full resolution are being created, therefore 1/3 of the full resolution should be in theory enough detail for the reconstruction and should get roughly the same amount of accuracy as the full resolution.

This of course does not count the texturing step into this as you would always want to use the full res for the texturing part.

Just a little side thought I have been thinking about ever since I started in photogrammetry, and my fascination by the foveon sensor. (I have not done comparison between the bayer and faveon, but would love to see some tests at full res)

Again just a little side note that could maybe in theory save a lot of processing time.

As well, if you are indeed running out of RAM with 96GB I would take into consideration to get something like this for RAM cache.

Any more info on this, I am trying to decide if to take 1.5GB or 3.0GB GTX 580 card.

Unless you have an urgent need for it I suggest waiting for the 680 release in april (or at least that is what the rumors say). http://lenzfire.com/2012/02/entire-nvidia-kepler-series-specifications-price-release-date-43823/

Yes I have been keeping an eye on this, I will then probably take the 1.5 as its cheaper... 

Can get this one for a pretty good deal.

P.s. the rumored 690 looks pretty good, 2x1024 Cuda cores... pretty insane. 1000$ price to go along with it.

Is there any gain for Photoscan to have a card with 3.0GB RAM instead of 1.5GB

For example you can get the GTX580 in 1.5 and 3.0 GB flavors

Often the 1.5 cards are clocked higher then the 3.0 cards so that would impact this as well.

What is the gain if any?

Yes as I stated I can do that, but that will result in Photoscan not clearing the cache used on Harddrive.

« on: August 25, 2011, 05:33:56 PM »

Sometimes if I cancel the Generating mesh stage, it can take more then 1 hour for it to cancel.

I can kill the app but that will result in not clearing the cache it has been using.

General / Nvidia Tesla and Photoscan

« on: August 16, 2011, 03:03:11 PM »

Can Photoscan use Nvidia Tesla cards, or is the missing shaders a problem for it.

Say for example the NVIDIA Tesla “Fermi” M2050 GPUs

Sent link to the file in email, would be great to get to know when support for EPSG::3057 is there, I guess adding EPSG::5325 would also be great, as its the same just newer.

Thanks.

I got a test file with rough 3 ground control points, meant for then EPSG::3057...

Will it help to send that one, or will the EPSG::3057 be no problem to add?
