Topic: Only getting 60% CPU usage with optimised app (Read 1182 times)

This is for my XP-M 3000 Athlon Laptop in a Asus A2500D but since running the optimised app, SaH_5.15_KWSN_......, it has reduced computing time from 80k secs to 36k secs, but am only using 60% CPU.? Any ideas about getting 100% would be great.
Thanks

Any ideas about getting 100% would be great. If the System Idle process is getting most of the rest of CPU, there could be a problem. If not, I think it may be a flaw in the reporting; certainly if the times you quote are for WUs of similar angle range the time reduction is about all you might expect from the optimizations. If you're running the graphic version with graphics on, that might possibly give such an effect since the default graphic settings allow that to use up to 50% of the CPU time. That can be improved from the project preferences page, either "Maximum frames per second" or "Maximum CPU % for graphics" (or both) can be reduced. Joe |

It appears that the balance of CPU% is idle. Am not running the graphics version. Cant find the preferences page, only running BOINC Manager if that makes any sense to you?

By preferences I meant the settings from the project "Your account" area. The graphics settings would be in the "SETI@home preferences" group, but you're not using that. The "General preferences" do have some settings which could cause BOINC to think you want it to idle tasks part of the time, I suggest you look there. Or you could find the global_prefs.xml file in your BOINC directory and attach a copy here. Joe |

If I'm reading that correctly, you have "Do work while computer is in use?" set to No. Mine's set to Yes, and has a <run_if_user_active/> entry.
That could be the key. Every time you touch a key or move the mouse S@H would be turned off, and not come back on until you were "inactive" for 2 minutes (the <idle_time_to_run>2).
