In your case, I guess that the file you are mmap-ing is too small to be the peak, and you do not have a detailed snaphot being taken between the mmap and the munmap. E.g. try to mmap a much bigger file, to ensure that the peak is reached by the mmap you are doing, and not any other operations. > BTW, would you please let me know how to compile and run the programs > in massif/tests? in valgrind top directory, to compile/install locally and run all regtests: ./configure --prefix=`pwd`/Inst make install make regtest Philippe ------------------------------------------------------------------------------ _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
