== Speeding up your code ==

First you should try to get an idea which routines are consuming most of your CPU time:

 * Use the "-p" option together with your usual compiler flags. 
 * Recompile the whole code.
 * Run the code with a sample job card. This will generate an additional file called "gmon.out".
 * After the succesful run, just execute "gprof main.x gmon.out" which gives you the amount of consumed CPU time per subroutines.


Now the hard part starts : Reducing the run time of the main consumers...
