Hi,
As mentioned earlier I am often stitching 500 or more microscope images.
I am thinking to get a new dedicated computer for this.
How much computing power can Hugin utilize (RAM, GPU etc)?
Does it make sense to buy a really high spec desktop computer with
high end graphics card?

Hello!
I don't know how much Hugin can utilize re RAM, GPU, etc, but I run
Hugin on a laptop with an 8-core/16-thread i9, 64GB of RAM, 2TB NVME PCI
drive. The laptop has two GPUs - Intel UHD630 and NVidia GTX-1650 Max.
I run Linux and have never been able to get any application to use the
GTX, but the Intel GPU works fine for remapping images.
I've done some big panoramas - not as many frames as yours! - and had
the system consume more than 64GB of RAM. I don't think the RAM
consumption is related to processes running on a GPU. It comes when
Hugin goes to the blending process. Hugin happily runs 16 threads and
takes as much memory as it needs.
I'm giving up on laptops as power computing platforms. While modern ones
can pack fast processors and almost enough memory, they can't dissipate
heat fast enough. Throttling kicks in, and then a processor capable of
hitting a nominal 5GHz is running at 3GHz instead, with a temperature
reported at 212F.
For comparison, the 2-core, no-thread Pentium 4 in my server (in a
midsize desktop tower case) is set to run a constant 3GHz (and does) and
runs at 110F. It never throttles.
My current plans would be for an AMD 7950X, 128GB (256GB if possible).
My current camera shoots 20MPX and I prefer to work with RAW and
high-dynamic range. I'm hoping to replace with camera with a 61MPX Sony
A7R IVA model, so I expect RAM consumption will go up a lot.
I don't know if the Windows version of Hugin supports NVidia GPUs better
than the Linux version does. I understand Linux supports AMD GPUs better
than the NVidia line.
I'm sure there are people on the list that know more about Hugin and
GPUs, maybe they have thoughts?
