TAU_ENABLE_INSTRUMEN(3)

Name
TAU_ENABLE_INSTRUMENTATION - Enables instrumentation

Synopsis

C/C++:

TAU_ENABLE_INSTRUMENTATION(void);

Fortran:

TAU_ENABLE_INSTRUMENTATION(void);

Description

TAU_ENABLE_INSTRUMENTATION macro re-enables all TAU instrumentation. All instances of functions and statements that occur between the disable/enable section are ignored by TAU. This allows a user to limit the trace size, if the macros are used to disable recording of a set of iterations that have the same characteristics as, for example, the first recorded instance.

Example

C/C++ :

    int main(int argc, char **argv) {
      foo();
      TAU_DISABLE_INSTRUMENTATION();
      for (int i =0; i < N; i++) {
        bar();  // not recorded
      }
      TAU_ENABLE_INSTRUMENTATION();
      bar(); // recorded
    }

Fortran :

    call TAU_DISABLE_INSTRUMENTATION()
    ...
    call TAU_ENABLE_INSTRUMENTATION()

Python:

    import pytau
    pytau.enableInstrumentation()
    ...
    pytau.disableInstrumentation()
