General / GPU Ram usage on multiple GPU's

« on: April 11, 2025, 06:44:31 AM »

I was recently shown a code block from Alexeys that estimates how much RAM texturing a block model will consume:

Code: [Select]

K = 3 #surface complexity and atlas filling coefficient
K_ghost = 60 #60 - with ghosting filter, 36 - without ghosting filter
texture_size = 16384 #pixels
block_size = 25 #meters
resolution = 0.00075 #m/pix resolution
N_pages = int((block_size / resolution / texture_size) ** 2 * K) + 1
req_memory = texture_size ** 2 * K_ghost * N_pages
print(N_pages, "texture pages, ", req_memory / 1024 ** 3, "GB")
I was wondering how the RAW allocation works with multiple GPUs? Will the texturing be split across the multiple units or should I be aiming for a single GPU to optimise performance?

Is it just me or is the change log on the Download page not updating after the 30th December 2024?
Last one listed is Version 2.2.0 build 19853 (30 December 2024).

Bug Reports / Generating Block Model from Depth + Laser Scans

« on: November 26, 2024, 07:24:54 AM »

I'm getting the following error whilst generating a Block Model from a depth + laser scan solution in Metashape Pro version 2.2.0 build 19522. This is occurring in the estimating resolution stage (~80%)

General / Cluster Processing Assistance

« on: October 02, 2014, 10:12:51 AM »

I am having some trouble getting my network processing up and running and was wondering if anyone else has had any experience with it?

I am able to start the server (Comp1) and connect two node computers to it (Comp1 and Comp2) which say they have connected to server at xxx.xxx.xxx.xxx:5841 (i left it default but it went to this). However, I am not able to connect to the server in Photoscan; it just hangs on 'connecting to server'.

Could it have something to do with having a node running on the same computer as the server?

Thanks
