Thanks for asking @idshklein. This package is still under heavy development, so not really ready for "general consumption" just yet, and also not really documented at all. Short answer to your question is here:
https://github.com/ATFutures/m4ra/blob/b57c1cb9c921082d086c68aab883254369ffe13a/R/utils.R#L29-L39
So you just need to:

Sys.setenv ("M4RA_NUM_CORES" = 4) # or whatever

Note that everything really is designed to run in parallel, and running on single core, or even only a few, will generally take a long time to calculate. You also need to actively look at dynamic memory consumption, because depending on how big your GTFS feed is, the routines can require more memory than what is available.

Can I ask what you'd be using this for? I'd be happy to help further if it's an interesting project. It's currently being tested exclusively for my own purposes (mostly https://urbananalyst.city), but would be great to have a second use-case for testing.
