Multi-GPU parallel computing

Hi!

Using demo_colmap + ba, but the memory usage is too high. I would like to know if there is a way to conduct multi-GPU parallel computing?

Thanks.

Hi! I’ve implemented support for multi-GPU parallel computing to address this issue. You can see the proposed fix in this pull request #445

Please let me know if you have any feedback or if further adjustments are needed:)
