   TSView()  to binary stores the ENTIRE TS state needed to run (yes including the function pointers provided by the user) and TSLoad() loads it back up ready to run again :-)

Note 1) it is still only proof of concept, I don't do anything with user contexts etc etc.

Yeah, this would need the user to provide create routines that started from scratch. Having that is actually relevant to UQ, so it may be worth adding.
 

Note 2) it, course, doesn't save state inside SNES, KSP, PC, or Mat nor should it ever. Those will all get rebuilt when the next TSSolve() is called.

Okay, it loads when I link with '-pie', but the binary file output from ex1 does not have the DM:
