dedoppler should be passed a GPU ID parameter for use with cudaSetDevice(gpu_id) Command line default: 0

Is it good enough to use the environment variable CUDA_VISIBLE_DEVICES ? I'd rather not support extra flags if there's already some way to do it.

texadactyl commented 2 years ago

rawspec, turbo_seti, and hyperseti have set a precedent by providing this flexibility

Should seticore become successful, this won't be the last user interface change

texadactyl commented 2 years ago

e.g. min_drift_rate which might be set quite high in the case of Mars

The author has the right to design how a specific device is selected. Therefore, I am closing this issue and opening a PR that just amends README.md to add a section on how to deterministically select a specific device using environment variables.
