Changes

Summary

1. Adding variables to openacc data statements. Without this, the code crashes when using the GPU with l_godunov_upwind_xpyp_ta=.true. (details)
2. Modifying compiler configurations (mainly optimization level) in order to prepare for switching scipts and tests to cmake, specifically separating out this BIT_CHANGING commit from the rest (details)
3. thlm_ed and rtm_ed caused GPU errors since those variables were added to a acc loop, but never added to the acc data statement. This change makes it so they're only calculated on the CPU, since they are only used for stats, fixing the issue without adding the GPU memory footprint. (details)
4. Adding -Mstack_arrays to the nvfortran flags causes us to use more stack space, which means we need to allow processes to use more stack space (when using lots of columns, since that increases memory footprint). We do by using using 'ulimit BIGNUMBER'. (details)
