This seems to be inline for what I'm looking for.

My university wants to buy a system, to initially process small to medium data sets, but that can be upgraded later.  I've been looking at this motherboard.  What you ya'll think?

http://www.newegg.com/Product/Product.aspx?Item=N82E16813182718

Which CPU should I use?

I would find something that uses DDR4 ECC RAM and not DDR3. DDR4 prices are just 10% more than DDR3 right now. If you want something you can buy RAM for now and expand on later then DDR4 will be much cheaper in the future than DDR3.

As for a CPU, the highest clock speed 2011-v3 6 or 8 core Xeon you can afford. Just remember, if your going to do a system with 2 CPUs it has to be a E5-2xxx CPU and not a E5-1xxx model.

For servers like this I like Supermicro units.

Drop the Intel CPU to 10/12 cores....you are dropping 1 physical core, 2 virtual cores, per GPU, not GPU cores

Here is the memory requirements PDF:
http://www.agisoft.com/pdf/tips_and_tricks/PhotoScan_Memory_Requirements.pdf

Full system requirements really all depend on what you are looking at modeling/how many pictures you will be taking and how long you feel like waiting

My workstation specs are:

Asrock X99 WS Motherboard
Xeon E5-1650v3 CPU
128GB Crucial DDR4-2133 ECC RAM
2 Tesla Co-Processors
2 GTX-780 Video cards
Samsung 850 Pro SSD Boot Drive
Crucial M4 SSD Working Drives

I have a feeling the complete white background is messing it up. Try putting something under the plate so it has additional objects to match and align the photos. Also try not doing a mask next time

With a 7 month year old baby in the house its hard to find time to get out and scan things....This will be most helpful

Thanks

General / Can someone upload test photos of persons full body
« on: April 27, 2015, 02:59:50 PM »
Just wondering if someone could upload a image set of a full body scan. Im wanting to test out a few things but I dont have any good images to work off of. Not looking for anything in particular, just good photos from head to toe so I can run it through Agisoft.

Thanks in advance

The fans im using were pulled from a 4U server. The reason they are running how is just simply becuase im not getting enough air directed through the cards, its going over and under....ill just wait for the water blocks to arrive, should help cool the room down as well.

Well these cards run HOTTTTTTTT! I thought my setup with a few 10,000RPM server fans forcing air into the cards would be good enough but I was wrong. I created a funnel to push air into each card and was able to do some basic 2-3 minute tests, but in those short periods the cards would ramp from 30-40C to almost 100C so anything over a small 50 picture project all at medium settings is not possible at the moment.

I ordered some water block for the cards on Sunday so I should be able to get some good tests not this coming weekend but the following weekend. I will also do a write up on cooling these cards just in case someone else goes this route down the road and needs to cool them as well.

for same price can get 2-3 gamer card that are much much faster...   

These were $75

General / NVIDIA Tesla Benchmarks

So I got tired of ray tracing taking forever and picked up a pair of Tesla cards. Figured I would give them a run at Agisoft and share some informaiton on them:

Nvidia Tesla M2090
6GB DDR5
225W TDP
Average power usage with Agisoft 150-180w
Idle power usage 20-30w
Idle temps 30-47C
Average temps under load 70-90C (passive cooling right now)
ECC Memory State turned ON

I am getting a lot of throttling use to temps right now, the case was not designed for passive cooling co-processors.  I have a few ideas I will be testing out this weekend to try adn get the load temps to under 70C all the time.  Ocne I do I will run the tests again. After multiples tests with the Agisoft benchmark data I got the following average samples/sec

Medium Reconstruction 500-600 million samples/sec

I think I might be able to squeeze a little more out of the cards by turning off ECC memory state, which will raise the memory bandwith. I will test this out tomorrow after I work on getting the cards cooler.

All in all I am very happy with these cards and their performance. They are under permorning the $300 GTX 780 cards I have, but at the price poitn I got them for, $75 each, they are simply amazing.

Just wanted to share since there has been a few other interested in Tesla/Phi chard performance. Check back later this weekend for more results

1. Do what @driftertravel said....get a older v2 CPU and find a used faster unit for the same price as the v3.
2. Just run standard SSDs, the speed will be there with the PCI-E units, but the question is really, will you see any benifits from it....and the answer in more than likely no. I think you would see better performance putting more money into a faster CPU or more/faster RAM

Which Titan-X version? I was about to upgrade to the new 12GB 2015 model and found out that the FP64 performance of the new cards is horrible compared to the older X model and Z units. Really just depends on if your software will take full advantage of the double precision workloads or not.

If you were just going to use the card for Agisoft the new Titan X card is showing great results, especially when it only uses 250w of power.

Are the tests with 2 cards with or without SLI disabled?

Are these the new 12GB cards?

Just read your other post and realized they are the new 12GB cards....performance is not what I was expecting. My GTX780 cards pull 700-800 million samples/sec and ran me $200 each. Crap, I really was looking forward to buying new cards this month. Guess I will just hold off for a little longer

On a side note, the 250w max power draw from each card is nice.
