Adds support for the nvhpc compiler and then recognizes derecho as a known machine (with intel, cray, nvhpc, and gnu compilers).
I should note that the netCDF Comparison (1 inst vs baseline) test fails on derecho for two reasons:
some values of fields that we know are very small went from truly being 0 to being round-off level
the threshold for acceptable relative errors in non-zero fields is exceeded
Both of these are addressed in #430 so I don't want to duplicate the fixes on this branch:
Instead of flagging values where baseline = 0 and new value is non-zero, we flag values where baseline = 0 and |new value| exceeds something like 1e-16
We have a different algorithm for computing relative error (denominator is the max over a three-point stencil), and have also adjusted the threshold. If this comparison still fails with the updated netcdf_comparison script, I'll increase the threshold accordingly
