Hi,
I am attempting to render a 308 tiff image panorama. Each image is 5760 × 3840 pixels. I left most settings on default but did choose Exposure Fusion. Whenever I attempt to render this panorama, it appears to "freeze" at the percent complete shown below. Pausing and restarting does not work, and the completion bar never gets farther along. It has been rendering about two days so far and I cannot tell if it is actually doing something or if it is just completely stopped. I can say that APG is using 6 gigs of ram and 90-95% of my processor so it is not just dead.
I have actually tried to render this multiple times now and it always "freezes" at the same point. Is there anything I can do about this? Do you have any idea if it is actually still rendering?
I am using APG 3.0.0 RC1 while running Windows 7 64 bit.
Thanks for your time.

In reference to http://www.kolor.com/forum/p87033-2011- … -58#p87033 I make the following calculation
Your images are of resolution 21 megapixels
21 * 4 * 308 = 25872 MB or 25 GB
25 GB of RAM memory would be perfect to do this panorama
You have 6 GB so 1:4 ratio of which we have stated that "Autopano will get the job done but you will experience it takes much longer to get things done. If you are on a budget and/or not making money with your panoramas, there is likely no real hurry to upgrade. Otherwise think about upgrading your RAM to get a better 1:n or adding a SSD as temp."
What kind of drive is your tempdrive on? A SSD or a normal harddrive? internal or external.?
From the taskmanager you can open the resource manager. How much activity does it show there?
How much GB are the files all together? What format/size are the originals? I ask as you might wanna ftp them to me so I can do the rendering on my machine.

Hi Hans,
Thank you for your help. I am actually just a hobbyist and am not even selling these photos. The panorama in this case is just of a cliff range and not even that special, but I'd feel better getting a final image out of it. I think my biggest mistake is doing it in TIFF format as I do not appear to have these issues with jpeg's. The TIFF files are much larger than the jpeg's so that could be part of it.
I will admit I didn't really realize I would need that much ram. I may have to use this as an excuse to upgrade. The temp directory and the photos are being stored on an internal raptor 10k RPM drive, but the final output was to an internal raid 5 due to file size. An SSD is on my list of things to buy someday. Maybe I will add it to my Christmas wish list. 
Assuming you mean Windows task manager, I see Autopano Giga using up 96% of CPU (ranging from 90-99% really) and just over 6 gigs of ram.
The pictures were taken with a Canon 5DMKIII in RAW format, so CR2's. I exported from Lightroom as TIFF's. I will get back to you in a couple hours on the exact total file size as I am at work right now.
I am really just curious if the CPU usage means Autopano Giga is still working and not just stuck in some endless computation loop. Since it has been running for just over 2 days now without the status status updating I was just not sure if it would ever finish.
Thanks again!

In windows task manager go to the fourth tab called performance. There you will find a button called resource monitor.
There you can see what your drives are doing. If files are still being written autopano is really doing something. Could also be just the pagefile is busy all the time.
Updating your RAM is always first thing to do to get autopano going. If possible and affordable it is best to go to a 1:2 or even 1:1 ration,. In this case 24 GB would be very, very nice. But 16 GB should also do very well already. I went from 6 GB to 16 GB and that took me for a certain testset from 9 hours to an hour. Then an pcie-ssd took me from an hour to 20 minutes..
