Massif Htcondor

Sometimes a condor tool or daemon is using a lot of memory, but isn't leaking, according to valgrind, but just has a lot of memory in use.

Valgrind's massif tool is an easy way to see what lines of code are responsible for the most memory allocations. To run massif, simply

  1. Run the program under question under massif with valgrind --tool=massif my_program my_program_args
  2. When the program exits (it will run much more slowly than usual), it will emit a file to the current directory called massif.xxxx where xxxx is the pid of the instrumented program
  3. ms_print massif.xxx will print out a textual description of the memory allocations made in the program
  4. If your system has KDE support, massif-visualizer may also show this info as a graphical program.
