TAU_MAPPING_LINK(3)

Name
TAU_MAPPING_LINK - Creates a mapping link

Synopsis

C/C++:

TAU_MAPPING_LINK(FunctionInfo FuncIdVar, unsigned long Key);

Description

TAU_MAPPING_LINK creates a link between the object defined in TAU_MAPPING_OBJECT (that identifies a statement) and the actual higher-level statement that is mapped with TAU_MAPPING. The Key argument represents a profile group to which the statement belongs, as specified in the TAU_MAPPING macro argument. For the example of array statements, this link should be created in the constructor of the class that represents the expression. TAU_MAPPING_LINK should be executed before any measurement takes place. It assigns the identifier of the statement to the object to which FuncIdVar refers. For example

Example

C/C++ :

    class MyClass {
      public:
        MyClass() { }
        ~MyClass() { }
        void Run(void) {
          TAU_MAPPING_OBJECT(runtimer)
          TAU_MAPPING_LINK(runtimer, (unsigned long) this);
          TAU_MAPPING_PROFILE(runtimer); // For one object
          TAU_PROFILE("MyClass::Run()", " void (void)", TAU_USER1);

          /* ... */
        }
    };
    int main(int argc, char **argv) {
      TAU_PROFILE_INIT(argc, argv);
      TAU_PROFILE("main()", "int (int, char **)", TAU_DEFAULT);
      MyClass x, y, z;
      MyClass a;
      TAU_MAPPING_CREATE("MyClass::Run() for object a", " " ,
                         (TauGroup_t) &a, "TAU_USER", 0);
      TAU_MAPPING_CREATE("MyClass::Run() for object x", " " ,
                         (TauGroup_t) &x, "TAU_USER", 0);
      TAU_PROFILE_SET_NODE(0);
      cout <<"Inside main"<<endl;
      a.Run();
      x.Run();
      y.Run();
