  1. Measuring Memory using valgrind CSCE 221H Parasol Lab, Texas A&M University

  2. valgrind • Instrumentation framework for dynamic analysis of programs (http://valgrind.org/) memcheck – detecting memory errors cachegrind – profiling cache / branch prediction helgrind – detecting races in parallel programs massif– profile memory allocation in heap / stack

  3. massif - heap ms_print massif.out.* valgrind --tool=massif --time-unit=B ./a.out

  4. massif - stack ms_print massif.out.* valgrind --tool=massif --time-unit=B --stacks=yes ./a.out

  5. Exercise • Write an iterative version of the all_true algorithm • Measure memory consumption using massif of both the iterative and recursive versions • Plot peak memory consumption for the following: • n = 101, 102, 103, 104, 105
