WRF Radiation Driver: Arithmetic Intensity

Home Previous page Next page

The page shows the results of measurement of the F/B of the WRF Radiation Drives, performed in the same way as described in the previous page.

The radiation driver does not use complex mathematical functions (EXP, etc.). The results do not depend on the grid sizes.

Once more, the F/B of the Radiation Driver is very close to the F/B of the HPCG for realistic cache sizes.
