@bobpaw I think that would work. My only concern with 'test compilation' to detect feature support is the added complexity when we have to cross compile. We haven't had a...
@bobpaw Good find. That looks good. Lets try it.
@bobpaw Does `PCU_Comm_Init()` check if MPI was initialized?
@bobpaw OK. I'm wondering if it will make sense to make the MPI check in that call, and if it fails call MPI_Init. But... handling MPI_Finalize could be a bit...
We should probably just make a PUMI_config.h file ([like this](https://github.com/SCOREC/meshFields/blob/main/src/MeshField_Config.hpp.in)) and the first entry in it can be the `SCOREC_NO_MPI` flag. Over time, we can move away from using `add_definition(...)`...
Are the `#ifdef SCOREC_NO_MPI` conditionals only used in the examples/drivers?
> SCOREC_NO_MPI is also likely exclusive with ENABLE_ZOLTAN since zoltan.h has `#include `. Hmmm. Zoltan can be used locally on each process (see the MPI_COMM = SELF) to do what...
@bobpaw Here is a comment that discusses running the delta wing regression test I mentioned earlier: https://github.com/SCOREC/core/pull/433#issuecomment-2516069759
We should check timing and quality.
@bobpaw Hmmm. I'm guessing that was a serial run? If so, I only have prior results for a 32 processes (see https://github.com/SCOREC/core/pull/433#issuecomment-2516069759). Regarding quality, if the final entity counts are...
