Unfortunately I want to use memcheck which seems to be impossible

Hello, Mr. Naderan.
What particular tool would you like to use (Memcheck, Callgrind, Massif)? If
callgrind - you can switch off instrumentation at the start and then switch it
on at some particular point (or time). In any case, at first - please test your
program with:
valgrind --tool=none ./path-to-your-program
If it spends a lot of time then probably Valgrind (like Memcheck, Massif, etc)
is useless for you because of time constrains.
I mean: None - is the fastest tool of Valgrind. It doesn't detect any errors,
simply run your code.
If it runs quite fast (for you) and you want to collect only call-graph (use
Callgrind) - then you can look at parameters for Callgrind.
