G-Parallel-Profiler

A parallel profiler that uses hardware performance counter to provide detailed function usage in each thread.

Example Output

Profiler output:
  thread 0:
    func1 800 cycles 80%
    func2 100 cycles 10%
    func3 50  cycles 5%
    func4 50  cycles 5%
  thread 1:
    func1 500 cycles 50%
    func2 200 cycles 20%
    func3 150 cycles 15%
    func4 150 cycles 15%
  ...

Example Usage

IMPORTANT: Remember to build your program with -g option which turns on the debug information.

cd test
make clean all
cd ..
make clean all

# Running a test program that uses four threads to do some random computation
./g-profiler test/test

# Running a password cracker program that cracks passwords in multiple threads
./g-profiler test/password-cracker test/passwords.txt

# Running a single thread computational intensive program (doesn't do anything)
./g-profielr test/calc
