To test our implementation, we 1) ported the existing
MPICH F90 test suite to F08; 2) wrote a set of new tests involving
F08 subarrays; 3) ported the NASA parallel benchmark
(NPB) 3.3 [3] to F08, which was originally written
using the F77 binding. The backend compilers we used include
a development version of gfortran 4.10 and the Cray
Fortran compiler 8.3.0. We compared performance of NPB
in F08 with that in F77 and did not observe any perfor
