I'm currently building a 16-core workstation to use with AutoPano Giga and I'm trying to decide on whether I should go with 128GB of 1600MHz RAM or 256GB of 1333MHz RAM. I will be working primarily with images in the hundreds-of-gigapixels range.
What would you recommend?

Would you mind sharing the more hardware info for 16 core setup?

Sure. Here are the primary components.
Case: Corsair 800D
Motherboard: Supermicro X9DAi
CPU: x2 Intel E5-2690
GPU: Undecided, but probably an Nvidia GTX 680
Boot Volume: OCZ RevoDrive 3 120GB PCIe SSD
RAID 0 Array for Storage: x6 Seagate Barracuda XT 3TB Hard Drives
PSU: Corsair AX1200
Offline
100drets of gigapixel...
256 minimum
6x3T Raid0... I would tripple this... 3raidcontroller with 6x3T each
For sorce inages, destination images and one for temp dir.

Brian what are you currently using?
You definatel will need something alot faster for your disk storage, and you need to calc in, your scratch disk/temp disk, i would probably look at something like 2x Areca 1882xi-24 channels with 4gb cache.
regarding the ram the quantity will be more important then the speed.
looking at your setup, i thnik you have heavily underestimated the importnce of our disk system...
i a just finishing off my upgrade to 96gb of ram and will post results later

Hi Brian
Prefere Quad channel RAM with a low timing (latency). With a QPI of 8 GT/s you have "only" a bandwith of 32GBytes/s (theoretically, in the best case)
The X9DAi need very expensive ECC DRx4 RDIMM's when using more than 128 GB.
So the 16x8GB setup will be the more economically solution.
Read the note 1) at the bottom of the RAM site in the manual (only 1GB, 2GB, 4GB DRAM's are validated)
See also the tested memory configurations on http://www.supermicro.com/products/moth … /x9dai.cfm
The Corsair AX1200 will definitely not be able to power this system at higher loads. Then you need two of this PSU's ![]()
What kind of work you are planning ? For video editing in full HD mode, 64 GB is more than enough.
APG is optimized to deal with really big panoramas (more than 20 GPixel) with less RAM. I'm creating 23 GPixel with 8 GB RAM in less than 2 hours (on a old intel x38 system).
If you like to create panoramas with hundreds of GPixel, you need to shot several thousands of single images with a super tele-lens (minimal 600-1000mm).
There is a critical time limit to do so. If you need more than 2 hours for shooting, the light conditions will change massively most of time.
But most robotic pano heads need several seconds for each image.
And at the end, how to publish such panoramas ? You can print it several hundert meters large ![]()
Or fill a separate server with only one panorama with one TByte of data ![]()

Thank you all for your replies. I have the storage system under control; I'm using a few other 6-18TB arrays each with hardware RAID controllers, but I was posting what I have just internally in this system. I apologize for not mentioning that previously.
Each of my RAID 0 arrays have read and write speeds in the 600 Mps to 1 Gbps range. Would you all think that those speeds would be sufficient enough when dealing with images this large?
Regarding the RAM, I suppose I will go with 256GB instead of 128GB of only slightly faster memory.
Thank you all very much for your advice. ![]()

By the way, do you actually recommend that I have 54TB of storage space available in the system?

Hey!
Sounds great! But did you think about having a very big image means a very big single file! Most RAIDs and SSDs have their main-speed with many small files - but not with ONE very big single file of 40GB for example! Opening that .psb file in Photoshop takes a while - and saving it takes another while . . .
Some (!) filters need another while additionally . . ![]()
I´m also thinking about new hardware - but it´s definitely not my interest to go into "hundreds of gigapixels" . . ![]()
best and good luck, Klaus

well ;-)
I think yes, if you try to keep the storages clean - I mean only holding images of the actual project. if project is finished move them to archive.
also depending on your workflow. if you must hold one set orig raws, 1-5 sets of developed raws, one set tifs and than playing with rendering results ... ;-)
I think yes to answer but finally you can fill any disksize...

Coming from a corporate IT, this setup could host a core of an enterprise back end system for hundreds of concurrent users, powering an organization with millions $ in revenue:)

ah - rather think its a basic setup for starting with kolors upcoming video-pano-stitching solution. and meanwhile we're waitung for the software he can do some gigapixel panos as warmup ;-)

I understand that the single final file will be very large; I am prepared to manage a single file up to 2TB in size. Although, I do have a question. I've heard that the maximum resolution for a PSB file is 300Kx300K pixels. What would you recommend I do if I'm assembling a file in AutoPano that I expect to surpass that size?

Okay, I see. Do you have a general size estimate of the total storage space each 100 gigapixel image would require, including source images, temporary storage and destination images? (For example, 5TB/100GP, 10TB/200GB, etc.) I'd just like to have a 'guideline' I can follow while assembling my disk arrays so that I can predict the amount of hard drive space I'll need. ![]()

You have to render it to KRO format. Works without problems ...
If you need to open the files with Photoshop you have to break it down to smaller pieces (krpano tools work great for this) ... edit the "smaller" files and then merge them back together ...

Brian - you say "hundreds-of-gigapixels", so I think it's safe to assume that you're talking about a minimum of 200GP, yes?
And I'm also assuming we're talking about "real" sizing here, and not some of the nonsense that's been created in the past?
OK. First off. Putting the computer hardware to one side for a moment, would you mind sharing how you're planning on shooting the images themselves?
The highest pixel-density DSLR out there right now is I believe the Sony A77. Forget the Nikon D800 - that's got a lower pixel density than even the Canon 7D, so if what you're after is shooting huge panos for the sake of shooting huge panos, the Sony is the logical choice.
Sony are releasing a 500mm f/4 lens this month. Slap that on an A77, shoot a full spherical panorama, and you'd be looking at something in the region of 300 gigapixels. That's of course assuming you can come up with a rig that can spin the thing through 180 degrees on the Y-axis (the lens is 37cm long).
Number of shots would be in the region of 22,000. Regardless of what pano head you use, that lens is going to take a good few seconds to settle, and you'll want the mirror up. So lets assume 5 seconds per shot. That's 30 hours of shooting.

Hi Gerald
My words, see above ! I shot in the past manual panos with 600mm tele and up to 2500 images - and get "only" 25 GPixel ![]()
Manually, I'm really fast, faster than most of the motorized panoheads, but I need also 2 hours for the shooting. And in this time, light change hardly.
But some students from California sometimes have crazy ideas, even with the hardware
And don't read our recommendations: think big but start small !
Offline
well. if money is no problem... why not. otherwise no single sportscar would be sold, no rolex would be sold ever etc...
and if finally wont do such x hundrets panos, well maybe he come to the idea he could/must use focus stacking for his below hundret pano... or he wanna create bracketing or hdrs...
and also not so far this year kolors koloreyes will be released and so maybe he comes to the idea to create some 15min. 5gigapixel pano videos...
so enough space for dreams ![]()
PS: time: none of the 1xx gigapixelpanos I saw was shot in one run... see also descriptions in kolors blog... they waited months to "catch" the fitting days to shoot the pano

Hi Georg -
Oh I couldn't agree more. It's great that there is someone out there with the resources and desire to push the envelope. I'm just not clear on the implications on what I refer to as the upstream side of things (i.e. actually shooting the images).
And koloreyes? What's that? Sounds intriguing!
Regards,
Gerald.

Hi Gerald
I like to push the limits too ! But for a rookie in pano shooting, I recommend to start small. Not with a pano of "hundreds of Gigapixel".
This may not go well, and then he loses the joy of it and threw the money out the window. That's what I mean.

still confounds me this type of purist pursuit of perfect gigapixels. Nothing wrong with it at all - just i dont understand, y'know why. I'd prefer to err on the side of making some pretty, but bloody big.

uups late with my reply...
use an webGL capable browser (see http://www.khronos.org/webgl/wiki/Getti … ementation ) and visit kolors page:
http://www.gigastitch.com/kolor-eyes-1.0/
(and be patient)
well - I wanted to test it myself now after some time. it worked for me in past, now I upgraded my browsers Firefox etc. and no videos are shown, only saying that loading has finished 100%... so dont know why its no longer working

I agree with that analysis and am too wondering what kind of shooting rig Brian has in mind, as well as the practical application of a 300GP image???

Its not that is an overkill, its more that it doesn't appear to have been thought through. To me is sound more like someone has gone...hmmm what will be the most extreme outfit I can put together...(sorry that should have been what is the most extreme outfit I get someone else to put together for me) but the more I read this the more I think we have a troll in our mix.
Having just added another 48GB of ram to my own system (total 96GB), plus adding more SSD drives into new and bigger arrays, I have also come to realise that, I am not able to push things through enough to maximise it. Secondly my current controllers now needs to be upgraded to bigger and faster controllers, so they too can take advantage of the added speed more and newer SSD's are offering.
Now this is a dual processor board that can be overclocked, and by adding more of the same ram, I now lost the option to overclock, as that ram isn't liking to get push. This means that at the next opportunity that ram have to be replaced, to better ram/different.
The moral here is that the more you add, the more can go wrong...I am not regretting building what I have done, but I am kicking myself for not having been able to forsee the new constrains that I am faced with.
As for the Rig to do a 22.000 image pano, I can only see the big Dr Clauss as an option. but It wouldn't be possible with just one rig, you would have to set up several rigs (Pano-heads)...even that would be a nightmare. lets just say that you have 6 rigs, covering 60+Degrees angle, they would still be shooting 5 hours, the light would change dramaticly in that period...obviously you could do in on an overcasted day...but who wants a grey sky!
BUT... I suppose from looking at your linked profiles, you do sit and play with a RED camera $$$$$... so given that little bit of info who is to say you don't have a few hundred thousands of dollars available to spend on a project like this. It certainly would be interesting to tackle and solve all the constrains a project like this would through at you.
Again, best of luck - it certainly is an interesting project! :-)
