Dear Jason,
in general fnirt isn’t really that hungry for neither memory or CPU. Can you please give me an example of how you use it and what the dimensions are of the data (--ref and --in) that you feed into it?

Even so, I was running into memory constraints on my desktop (which has 12Gb), and so I have moved my code to a supercomputer that can allocate 64Gb of memory for each process. This seems to have solved the memory issues; however, several of the calculations are taking a long time, and I keep having to adjust my wall time and start the calculations all over again - which is wasteful.
