NAME

       TAU_PROFILE_SET_CONTEXT - Informs the measurement system of the context id

SYNOPSIS

       C/C++:

       TAU_PROFILE_SET_CONTEXT(int context);

       Fortran:

       TAU_PROFILE_SET_CONTEXT(integer context);

DESCRIPTION

       The TAU_PROFILE_SET_CONTEXT macro sets the context identifier of the executing task for
       profiling and tracing. Tasks are identified using context, context and thread ids. The
       profile data files generated will accordingly be named
       profile.<context>.<context>.<thread>. Note that it is not necessary to call
       TAU_PROFILE_SET_CONTEXT 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_SET_CONTEXT(1);
         /* ... */
         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)
               call TAU_PROFILE_SET_CONTEXT(1)
             ! 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
