CPU profiler

1. CPU profilter
1. 1 gprof, Valgrind and gperftools - an evaluation of some tools for application level CPU profiling on Linux

1.2 List of performance analysis tools

2. Valgrind
 - memory leak profiling: $ valgrind ./sample
 - cache profileing: $ valgrind --tool==cachegrind ./sample
 - function profiling: $ valgrind --tool==callgrind ./sample
 - kcachegrind (GUI tool)

3. gprof

 - How to install and use profiling tool Gprof on Linux
 - GPROF Tutorial
    To write the gmon.out file properly, your program must exit normally. _exit()
    Call graph: gprof2dot
 - gprof Quick-Start Guide

• use the makefile (edit CFLAGS / FFLAGS first) or call compiler at the shell
• required flags for profiling: -pg -g
• try with and without inlining: -finline / -fno-inline
