Default loaded module is PrgEnv-nvidia on Polaris. If not swapped to PrgEnv-gnu, all Fortran test programs failed when running darhan-test/regression/run-all.sh. Only C and C++ programs ran fine.

According to Phil, Darshan is usually built with gnu compilers on DOE parallel computers, because then the library can be safely linked into executables built with any compiler.
