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_LINKcreates 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();
