TAU_MAPPING_CREATE(3) TAU Mapping API TAU_MAPPING_CREATE(3)NAME
TAU_MAPPING_CREATE - Creates a mapping
SYNOPSIS
C/C++:
TAU_MAPPING_CREATE(char *name, char *type, char *groupname, unsigned long key, int tid);
DESCRIPTION
TAU_MAPPING_CREATE creates a mapping and associates it with the key that is specified. Later, this key may be used to retrieve the
FunctionInfo object associated with this key for timing purposes. The thread identifier is specified in the tid parameter.
EXAMPLE
C/C++ :
class MyClass {
public:
MyClass() {
TAU_MAPPING_LINK(runtimer, TAU_USER);
}
~MyClass() {}
void Run(void) {
TAU_MAPPING_PROFILE(runtimer); // For one object
TAU_PROFILE("MyClass::Run()", " void (void)", TAU_USER1);
cout <<"Sleeping for 2 secs..."<<endl;
sleep(2);
}
private:
TAU_MAPPING_OBJECT(runtimer) // EMBEDDED ASSOCIATION
};
int main(int argc, char **argv) {
TAU_PROFILE_INIT(argc, argv);
TAU_PROFILE("main()", "int (int, char **)", TAU_DEFAULT);
MyClass x, y, z;
TAU_MAPPING_CREATE("MyClass::Run() for object a", " " , TAU_USER,
"TAU_USER", 0);
MyClass a;
TAU_PROFILE_SET_NODE(0);
cout <<"Inside main"<<endl;
a.Run();
x.Run();
y.Run();
}

TAU_PROFILE_SET_NODE - Informs the measurement system of the node id
SYNOPSIS
C/C++:
TAU_PROFILE_SET_NODE(int node);
Fortran:
TAU_PROFILE_SET_NODE(integer node);
DESCRIPTION
The TAU_PROFILE_SET_NODE macro sets the node identifier of the executing task for profiling and tracing. Tasks are identified using node,
context and thread ids. The profile data files generated will accordingly be named profile.<node>.<context>.<thread>. Note that it is not
necessary to call TAU_PROFILE_SET_NODE when using the TAU MPI wrapper library.
EXAMPLE
C/C++ :
int main (int argc, char **argv) {
int ret, i;
pthread_attr_t attr;
pthread_t tid;
TAU_PROFILE_TIMER(tautimer,"main()", "int (int, char **)",
TAU_DEFAULT);
TAU_PROFILE_START(tautimer);
TAU_PROFILE_INIT(argc, argv);
TAU_PROFILE_SET_NODE(0);
/* ... */
TAU_PROFILE_STOP(tautimer);
return 0;
}
Fortran :
PROGRAM SUM_OF_CUBES
integer profiler(2) / 0, 0 /
save profiler
INTEGER :: H, T, U
call TAU_PROFILE_INIT()
call TAU_PROFILE_TIMER(profiler, 'PROGRAM SUM_OF_CUBES')
call TAU_PROFILE_START(profiler)
call TAU_PROFILE_SET_NODE(0)
! This program prints all 3-digit numbers that
! equal the sum of the cubes of their digits.
DO H = 1, 9
DO T = 0, 9
DO U = 0, 9
IF (100*H + 10*T + U == H**3 + T**3 + U**3) THEN
PRINT "(3I1)", H, T, U
ENDIF
END DO
END DO
END DO
call TAU_PROFILE_STOP(profiler)
END PROGRAM SUM_OF_CUBES

Hi,
char *s="yamaha";
cout<<s<<endl;
int *p;
int i=10;
p=&i;
cout<<p<<endl;
1) For the 1st "cout" we will get "yamaha" as output. That is we are getting "content of the address" for cout<<s.
2) But for integer "cout<<p" we are getting the "address only".
Please clarify how we are... (2 Replies)
