Kokkos automatically manages parallelism when running make but this uses too many resources when running with the Cray compiler. Causes compile errors because /tmp is exhausted.

Marking this as a compiler issue just to tease you ;-)

Here you go. I don't have it used yet inside of test_all_sandia though. And regarding compiler issue: maybe the Cray software stack should somehow manage to deal with this. I can compile this on my macbook air with -j.

Now it only runs a single compilation at once, so very slow. What we would like is to just have make -j <n> work if possible (for the user).

Uhm no it shouldn't. I did test this, by default it does -j 32, and you can overwrite the value by --make-j=16 for example as a command line argument to generate_makefile.bash.
