No, the memory leak won't damage the computer. Part of the issue in this
thread is that we're mixing two terminologies. Your Valgrind report
reported several memory issues but as John already pointed out, that's
normal for all known MPI stacks. You have a real memory leak in addition to
the MPI memory issues. If you run your code, the message you are seeing
about "memory leak detected" is coming from libMesh's reference counting
system. It means that you're not properly releasing a libMesh resource. It
also tells you the next step in tracking it down which you should follow.
When you recompile libMesh with the --enable-reference-counting flag,
you'll see information about which resources were not released which should
help you track them down. Valgrind can also do this, but it takes a little
skill to use the right options and read the report to find things.
To answer the second part of your question about the implications, it
basically depends on the kind of memory leak you have. If you are just
forgetting to release a small finite number of resources that's not a big
deal. The OS will always clean up after you when your program terminates.
It's just a little sloppy. If however you are failing to release new
resources over and over during a simulation those kinds of leaks are much
worse. You may eventually run out of memory and go into swap, crash the
system or make it otherwise unresponsive. Either way a quality program will
always "behave" and clean up after itself so it's a good idea to do so even
if your memory leak is the less destructive kind.
