GiBUU

## Speeding up your code

1. First you should try to get an idea which routines are consuming most of your CPU time:
• Rebuild the whole code with "make MODE=prof" (works with ifort and gfortran).
• Run the code with a sample job card. This will generate an additional file called "gmon.out".
• After the succesful run, just execute
 gprof GiBUU.x gmon.out

which gives you the amount of consumed CPU time per subroutine.
1. Now comes the hard part: Reducing the run time of the main consumers ...
