MPI Needed ?
I don't know if it's unique to my machine or not, but I need to explicitly declare that I want to use MPI to get a working build.
If I run cmake ..
with no option then compile, I get errors (mpi.h not found), but it works if I use -DENABLE_MPI=ON
.
Do we want the code to be usable without MPI ? If yes, some additional checks might be required. If not, why not get rid of the option completely?
