Title: Photoscan Peformance on Dell server without GPU
Post by: marg on September 25, 2015, 11:25:04 AM

Hi,
just wanted to know if anybody has got experience running photoscan for aligning and point cloud generation on a server with no GPU. The server is a Dell r520 with 2*6 core Xeons with HT. It also features 96 GB of RAM. It will be running Ubuntu. How will the performance of this system compare to a regular desktop machine with dedicated GPU (like an i7 GTX 980 combo with 16 GB RAM)
Any ideas?

Hello marg,

GPU is used only for the depth maps estimation (sub-step of Build Dense Cloud stage), so the presence of GPU will not give any effect on the Align Photos stage.

So does that mean that particular step (which is very important for me) will not work at all, or will it just be slower?

Just slower than the same machine with a high speed GPU. But it may be faster than some machines with GPU.

Ok, I'll try it then, thank you!
