I am still getting out of Memory error...

Photoscan has used all the RAM and has cached just over double the RAM as well, see here in the Screenshot it stopped at 111GB.

I have around 600GB in Virtual memory + RAM but it does not seem to be used. What can be done about this?



I get this in the console.

Error: bad allocation
Finished processing in 82892.9 sec (exit code -1)


Here is from the Console, it didn't allow me to post the whole text from the console due to 2000 character limit.

And I guess its worth asking, the Generating Mesh step, is that a single thread process... If so, using the full potential of RAM speed would not be necessary anyways.

I am not sure how much RAM you need to be able to work with such a set I am working on right now, I don't think it is wise to try and put it all in RAM, you might as well cache some of it, yes it takes time to process but again, it will finish.

I have now about 1TB in virtual memory + the 64GB in RAM.

I am using This Motherboard...

http://www.msi.com/product/mb/X79A-GD65--8D-.html

And I have 8x8GB in the motherboard. It does support 128GB but it is very pricey due to cost of 16GB chips.

Right now I am processing a set with 38 x 195Mpix photos.

Buying a dual socked motherboard is not an option right now.

I am fine if the process takes a week, as long as it is able to finish.

Yes I am in the process of finding the 1 bad one, I have narrowed down to 4 modules and soon narrow down to 2 modules.

But What I meant is when I need more then 64GB to process dataset I can still use Windows virtual memory to process the dataset. I know it will be slow but it can be done.

So you are saying it is better to have Windows take care of the Swapping as virtual memory? Then something that could be built into Photoscan.

Well maybe there is a faulty memory in my system.. been running a test on the RAM.



Might be the reason for the error, I still would like to see a cache option in Photoscan.

I used WinDbg to take a look at the BlueScreen dump file, in the bottom it states.

Code: [Select]
Probably caused by : ntoskrnl.exe ( nt+3ceb8 )

General / Cache directory in Photoscan
« on: April 05, 2012, 01:08:44 PM »
When working on larger projects where more RAM is needed towards the end of the Meshing would it be possible to have a caching directory in Photoscan to cache to instead of using the Windows Swap file, most software is set up this way.

Reason I am asking is I have assigned swap file in Windows but Photoscan keeps on bluescreening when it starts to swap.

I know it will be slow, but processing can then be done on larger sets, there are fast SSD solutions out there that can be used.

So could you please add internal Cache/Swap to Photoscan.

Does swapping from the GPU cause any problems maybe, is that why I get bluescreen?

P.s. I have 64GB of RAM but I am still running easily out of RAM. And there is not really any indication how much more RAM I need.

And, actually, if you use Ground Control before meshing will it be faster at meshing as it will know that only x many images are visible in each section of the mesh, or will the bundle adjustment have already taken care of that.

So I add to this question, if the images are aligning fine using 100.000 points per image is there any reason to use 200.000 points or more. Or should I even use less to speed up the process.

Yes I changed the max to 200.000 in preferences, and it is finding 200.000 points per image just fine.

Will this have any impact on the Meshing, or accuracy of the model in any way...?

You do get the option of doing pair selection in Align images if you have ground control points in the images before.. but still wonder if it does change anything in the process.

I would look into getting a Canon 5D Mark II and a 24mm TS Mark II lens...

Or look at the new Nikon D800 or D800E, not sure what lens to look for there.

Does it matter if I add GPS iformation per image before or after the align images is run?

Will it improve the alignment?

Oli, you must be a first tester. from what i know from Agisoft, reconstruction routines use single precision arithmetic, that mean the 680 could speedup the process. But still need someone with the card..

I think I will stick to the 580 card for now, I might just get another one of them as they should get cheaper now being an "old" card now.

What about the Nvidia Quadro cards, are they outperforming the gaming cards in Photoscan or is it the other way.
