+        GPAW is a density-functional theory (DFT)
+        program for ab initio electronic structure calculations using the projector
+        augmented wave method. It uses a uniform real-space grid representation of the
+        electronic wavefunctions that allows for excellent computational scalability
+        and systematic converge properties.
+        The GPAW benchmark tests MPI parallelization and the quality of the provided mathematical
+        libraries, including BLAS, LAPACK, ScaLAPACK, and FFTW-compatible library. There is
+        also an experimental CUDA-based implementation for GPU systems, but it is not covered
+        by this UEABS release.
