Exercise 9: An evaluation of the Persian Gulf Tidal Model for various platforms and with slight changes of the input parameters.

a) Determine the time that it takes to execute the Persian Gulf Tidal Model on the Sparc workstation, the CRAY YMP, and CM5.

b) Try your hand at running different tidal components or all of them, from scratch, by changing the TIDE variable in pegtdu10 appropriately. Make sure ITDASM=0. Make sure you save the resulting pegfldtd files, if you plan to continue the runs further in time.
