[Feature Request] Multi-GPU Support for 3DVA


The 3D variability job is taking a long time. So I checked if I can use multiple GPU. I could not see an option for it. May I please know if the 3D variability job can be executed using multiple GPU.


@iswaryapj Have you tried downsampling your particles? Downsampling to a box size of 128 or even 84 results in 3DVA to speed up exponentially. Once your variability analysis is done, you can “upsample” your particles for further refinements following these instructions. Works like a charm.
