(I) How to make the program run faster through Valgrind profiling? I know I
should use cachegrind and callgrind, but I don't know is what things I should
pay attention to from cachegrind/callgrind reports, what properties
have significant impact on speed;
Bruno already answered this, but I wanted to point you at the introduction of
step-22 for an example.
As for your other email: 10 MB of leaks is small potatoes compared to the 10
GB you allocate. You will have to figure out where all that memory is
allocated. My recommendation would be to debug these sorts of issues on a
local machine, rather than a cluster. You could set up a smaller test case
that runs faster.
