Using jetson nano as an external gpu

Hi, I wanted to use the jetson nano as an external GPU to support the computationally intensive program (FSL – analysis tool for FMRI, MRI and DTI brain imaging data) and on the website they state that the program has been parallelized with CUDA v9.1, which allows the use of an Nvidia GPU if one is available on the system. But I wasn’t sure how I would go about achieving this. Thank you in advance.

I can’t say for sure, but most programs on desktop PC architecture know about what is available through PCI functions, e.g., nvidia-smi. The GPU on Jetsons are directly wired to the memory controller, and thus are invisible to PCI. So I doubt you could do this (and the PC drivers are not meant for anything but PCI on x86/x86_64/amd64).
