Detecting Bugs and Bottlenecks in C/C++ Sources (Linux)
Here is a whitepaper about the detection of bugs and bottlenecks in C/C++ source codes under Linux. The whitepaper will show you how to use Valgrind and gprof.
Valgrind is a set of debugging and profiling tools including Memcheck (memory error detector), Cachegrind (a cache and branch-prediction profiler), Callgrind (a call-graph generating cache and branch prediction profiler) Helgrind and DRD/ (thread error detectors), Massif (a heap profiler).
gprof is the GNU profiler (see here for more details) and it provides the same kind of information than Callgrind, but faster.
