compute capability check

[natowi]

In the public release we state: "The binaries are built with CUDA-12 and are compatible with compute capability >= 5.0."

However, internally we still reference at least cc2.0:

AliceVision/src/software/pipeline/main_depthMapEstimation.cpp

Line 253 in 48c8f8f

ALICEVISION_LOG_ERROR("This program needs a CUDA-Enabled GPU (with at least compute capability 2.0).");

Should this be updated?

I'd vote for adapting the logging message :D.

We require CUDA 11 in CMake here. And the CUDA 11 toolkit only supports 3.5-5.0 as deprecated architectures (see here).

So 2.0 is definitely wrong. Question being: Should that be changed to 5.0 (which is deprecated) or 5.2 (which is the oldest non-deprecated microarchitecture afaik, see here).

EDIT:

Just had a look at the devices affected, and I must say that microarchitecture <=5.0 are ancient. If anyone is still using these, they probably don't have a good time anyway :D.
