Does pipeline.sh use GPU?

[tashrifbillah]

epi_reg distorted b0 to T1
epi_reg --epi=/INPUTS/b0.nii.gz --t1=/INPUTS/T1.nii.gz --t1brain=/tmp/tmp.z3zFpgMgdl/T1_mask.nii.gz --out=/tmp/tmp.z3zFpgMgdl/epi_reg_d
Running FAST segmentation
FLIRT pre-alignment
Running BBR

Shouldn't this step use GPU? nvidia-smi command does not print an associated GPU process at the time of running.

I'm not a developer or expert with this program. However, I'd say no.
Those are just FSL programs. They use CPUs and can use multiple threads.

AFAIK, nothing in the pipeline uses GPU. The model is already built and so inference is just a forward run through the model and uses CPU. IN fact, I know that the torch library in the container version, was not compiled for GPUs.
