How to tell what I_MPI_ADJUST are set to with Intel MPI 19

$

Is there a way with Intel MPI 19 to see what the I_MPI_ADJUST_* values are set to? 

With Intel 18.0.5, I see a lot like:

[0] MPI startup(): Gather: 3: 3073-16397 & 129-2147483647
[0] MPI startup(): Gather: 2: 16398-65435 & 129-2147483647
[0] MPI startup(): Gather: 3: 0-2147483647 & 129-2147483647
[0] MPI startup(): Gatherv: 1: 0-2147483647 & 0-2147483647
[0] MPI startup(): Reduce_scatter: 4: 0-0 & 0-8
[0] MPI startup(): Reduce_scatter: 1: 1-16 & 0-8

On my cluster which admittedly only has Intel 19.0.2 at the moment installed, I tried running various codes with Intel MPI 19.0.2 and I_MPI_DEBUG set from 1 to 1000 and...not much. For example, when running a hello world:

(1189)(master) $ mpiifort -V

[0] MPI startup(): 2       126172   borga065   {20,21,22,23,24,25,26,27,28,29}
[0] MPI startup(): 3       126173   borga065   {30,31,32,33,34,35,36,37,38,39}
Hello from thread    0 out of    1 on process    1 of    4 on processor borga065
Hello from thread    0 out of    1 on process    2 of    4 on processor borga065
Hello from thread    0 out of    1 on process    3 of    4 on processor borga065
Hello from thread    0 out of    1 on process    0 of    4 on processor borga065

Honestly I'm used to I_MPI_DEBUG being *very* verbose, but I guess not anymore? Is there another value I need to set?

Thanks,

Matt
