It is not clear what you mean by "CPU utilization" here.

No it does not.  It shows you how the CPU time that was consumed by the 
program was divided up amongst the functions that make up that program.

Are you referring to how much CPU time a given program is using over 
specific time periods ?  In which case a tool like "ps" or "top" can 
probably give you the information you need.

Or maybe you want to see a graph of which function was consuming CPU 
cycles at any given point in time ?  This information is recorded in the 
gmon.out file produced by a profiled program, and the format of this 
file is documented.  (See gprof/gprof.texi).  You will probably have to 
write your own tool to extract this information in the format that you 
desire.
