Print "Approximated Real Time"

[TApplencourt]

Some users want to know how much time their application run (real time ).

We cannot have this value in THAPI, but we can provide a approximation:
time_last_message - time_first_message.
If we assume that people start with Zenit/CuInit and stop with zeFinalize/CuFinalize this can be good enough.

Things to do:

• Modify the tally to save the first and last message (

  THAPI/xprof/tally.cpp

  Line 95 in 8096497

  for (uint64_t i = 0; i < message_count; i++) {

  ) and display it
  • Need to think of how to take care of multi-process ( do we want max - min global, or per process than then do the max)
• Choose the correct string to display: Approximated Real Time? Runtime real-time? Elapasted Time for the runtime?
