    COUNT_WARP_LEVEL = 1 - Count warp level or thread level instructions
    EXCLUDE_PRED_OFF = 0 - Exclude predicated off instruction from count
   ACTIVE_FROM_START = 1 - Start instruction counting from start or wait for cuProfilerStart and cuProfilerStop
       MANGLED_NAMES = 1 - Print kernel names mangled or not
