Dear G4,
I am doing some basic calculations to test the new I9-13900HX CPU with GEANT4.
I have tried in multithread and monothread and I get similar behavior. I am not using the viewer.
The real time of calculation is always above the CPU time of calculation as you can see below for 1 thread:
Number of events processed : 500
User=37.047000s Real=236.042703s Sys=0.281000s [Cpu=15.8%]
It is like if the CPU is not used in totality because the USER time (understand CPU calculation time) is 37 sec while the real time to execute the calculation is 236 sec. I have checked that this time does not include the initialization but only the run time.
I do not understand this behavior. Do you have any hint ?
