hello, I noticed that Valgrind maybe use memory more than twice orignal memory that program need in your guide, Now I got a error from valgrind which hint me that I have use more 32G memory on 64-bit platform, My program orginally use 5G memory ,when I use helgrind to analyze my program, I found it really used more than 32G memory(use top -p pid to see), My answer is that helgrind really need more than 6 times or even more memory than before ,is that true? or helgrind have a bug? By the way ,my program have used mmap function. |
