Any computer builders here?

It'll use 100% no matter how much CPU you give it.

Thats a very capable box you built there.

You are about at the threshold of bang for buck.

Any additional money you toss at it won't necessarily return an increase in processing that makes ROI sense.

If you really need to get more performance down the road you'd be better served building smaller (cheaper) i7 single GPU boxes and doing distributed rendering, basically build a render farm.

Yea, I know. But I have several map programs that make and work with giant tiff files. If they would put a radio button that say write it anyway it would be great.

Those apps may be using the non standard non certified bigTIFF 64 bit variant.

It's not a certified spec and does not have a unique file extension.

Adobe does not get to define the spec or certify it.

Allowing the files to be saved as a .tiff in 64 bit vs the certified standard 32 bit would be an extremely bad and horrific decision.

It'd be like if Shell formulated a new gas that only 1% of internal combustion engines can use but put it on the market as Regular Unleaded.

There are agreed to standards that the industry complies with for a reason.

The best CPU for this kind of work is actually an i7 8700.

This is not the type of stuff where raw performance numbers translate to actual real world performance.

nVIdia CUDA 2 GPUS are a must and one would think a $4,000 Tesla V100 would blow away the GTX 1080's he has in there and in nearly every function required it does, exxxcccceeeeptttt for one. The Tesla is a pig at depth map calculations and it's poor performance on that more than erases any gains in the other nodes of the processing pipe. It ends up being slower at 4x's the price.

Like a Top Fuel Rail it will beat everything to the other end of the track, but take it to a track with turns, not gonna do very well.

Thats a very capable rig he has there for what he needs to do.

This is all fascinating, before this build, I had no idea someone would need so much power out of a rig.

I just want to be perfectly clear, I am not here arguing or bashing anything, I am reading and learning. If I asked a question or made a suggestion, I was just trying to understand what was going on and hoping I could be helpful with my limited knowledge.

I have built a couple of machines in the past, I push my kids to always build theirs. My 16 year old wants a gaming rig, I told him he has to build it. I prefer them to learn how it all works together over just buying a built box, that will always have corners cut. The gaming rig my 16 y/o is building cost about $850 and will out perform machines that cost 2X if you bought a complete one.

Some deal with my older son when he wanted a rig. He now builds machines for all his friends.

I want to build a new one now, except I really like having laptops as my processing needs are no where near what Glen is doing.

My only suggestion would be to explore liquid cooling for the CPU. My older son experimented with it and said hands down, the liquid cooler is way more efficient.

Yea, I understand standards. Good idea, however if they would let me “play outside the box” I would love it. As it is, I have to cut the giant mosaic into 25 or more pieces, tweak every piece one at a time, reassemble it using the world file made when I cut it up, then make a new giant mosaic in a standard format. Not many if any clients want a 50 gig tif file. So I make a Mr Sid or Jpeg2000 file to send via FTP.

The files I used to make the final product get deleted, as they are not needed anymore. And Photoshop will not read the JPG2000 file made by mapping programs.

I must be missing part of your pipe but why not just open and edit / color tweak your bigTIFF then save as jpeg2000 from Photoshop since that sounds like your final deliverable format anyway?

The photoshop version of JPG2000 is somehow different than the one my mapping software makes or ready. Photoshop just says it is not the right type of file. It has to retain the geotag header as that keeps the image positioned on earth in the proper place and scale.
