cpu time

  simu simu-reco real-reco
compiled 1.08788949 0.471163 0.185127714
non-compiled 1.0850429 0.480806 0.185445857
32-bit 1.0845695 0.475669 0.182371785785
comparison <0.3% ~1% ~1%
From the above table, we can see cpu time consumed in both modes are very close to each other in the error range.

memory usage

  • There are two measures of memory to be monitoring here: VSize, RSS
  • The process is to be monitoring: simulation, simulation-reconstruction, real-reconstruction
  • virtual memory (VSize)
Vsize(MB) simu simu-reco real-reco
compiled 588.4 499.4 583.7
non-compiled 586.6 497.4 583.2

  • summary
    • From the above monitoring pictures, no memory leaks are found
    • vsize is 584MB, rss is 277MB in average.
