Speeding up finalize

Hi.  I'm wondering if there are any tricks to speeding up finalization.  My jobs usually run for 4-6 hours, of which maybe one or two hours has profiling enabled.  However, finalization can take 2-4 days.  I've tried limiting the sampling rate and the total data stored, but even then it still usually takes 10x longer to finalize than to profile (I have this sense that this didn't use to be the case when I was last using vtune a few years ago; perhaps I was using an older version?).  I'm currently using VTune  2019.  If it will make a big difference I could try to get it upgraded, but the tools are managed centrally so that's not always easy.  I'm hoping there are some things I can do to bring the finalization time down without losing too much in the way of profiling coverage.

Thanks,

Ben

Hi,

Thanks for reaching out to us.

Could you please share the following additional information :

1. Which analysis you are trying?

2. Which application you are using?

  1. I’m just doing regular hotspot analysis
     
  2. As for which application, I’m not sure if you are asking which vtune application (I’m not aware of more than one), but you are asking that, it’s “ample-cl“.

Can you provide details of the system on which you are running, how you are running your collection, and what application you are analyzing?

I'm not sure exactly what kind of information you are looking for.

  • The system is a redhat 6 linux system with a xeon processor using VTune 2019
  • The command is usually run like this "amplxe-cl --start-paused --collect hotspots <command>"
    • The program internally turns on and off profiling around the specific code that needs to be profiled
  • The application being profiled is a compute-intensive CAD tool
