interesting..
My machines run BOINC client and I find that background processes affect them noticeably AthlonXP 3000+ 500MB generic PC3200 Ram= average 5.7 hours (no significant background work) AthlonXP 3200+ 1Gb Corsair PC3200 Ram = average 6.2 Hours (main general useage, lots in background) On the subject of background operations. I have noticed that "BOINCview" grabs 40 -50% + processor time at regular intervals.  Does anyone know of another program that does a similar job without the resource penalty? Cheers. ozylynx  |

I have noticed that "BOINCview" grabs 40 -50% + processor time at regular intervals. Really? Strange... I run BV 24/7, with it constantly pinging the other system every 10 seconds for updates via RPC, and it's only used about 25 CPU seconds in the last day. I don't think I've ever seen it put any noticeable load on the machine. I wonder what the difference is from. Sorry, I don't know of anything comparable. |

Ozylynx, how does your BV communicate with BOINC.... direct or via the network option? With latter and Contact frequency at 15s and Offline refresh 30s, its build up 12 minutes of cum CPU time per taskmanager on 3.5 days uptime on my box. Log is set at 7 days to display in e.g. Work Completion tab.
----------------------------------------There are a few posts on BV on the forum here and the unofficial BOINC wiki does have a configuration page.....works like a dream. ciao

Mine is pinging every 5 seconds on 8 threads and the % use is momentary but still there. As seen in Windows Task Manager. I know that 'cumulative use it is probably small, but given the apparent delay in BOINC coming back to full usage, I think the overall CPU time lost would be significant, Cheers. ozylynx |

Display the "CPU Time" column in the Task Manager process tab.

Hi Didy
I can't find the "CPU time" in the processes tab. There is a CPU tab there which I use now, but that onlty seems to show % useage in realtime. Cheers. ozylynx |

hmmmm Windows or Linux? The Windows version in the Processes Tab allows adding of many columns such as the mentioned cum time, peak ram use, memory increment change, virtual memory et cet. Open the View Menu to add / remove.
----------------------------------------ciao PS, posted a specific Taskmanager Member Tip "SR 03-06" on the how too's

Tnx Sek that did it.
Out of interest, BV took 5:18 WCG = 70:00. That's not a small proportion. About 1:49:00 lost per day!!! I think some time checking config files migh be well spent. Cheers. ozylynx |

Careful what you're comparing. The cumulative CPU time is from the time the process started executing. BV will have been running continuously since you started it, but WCG starts a fresh process for each WU. So unless you just booted your machine 70 minutes ago, they're not comparable. How long ago was BV started? 5:18 might not be bad if it's been running for a couple days or more.
But anyway, are you using the "Get data via direct file access" or the "Get data via network access" mode in the Locations options? Network mode will be much more efficient than file access mode. Much better to send a short message and get a response, than to do all the overhead necessary to open and read several remotely mounted disk files every update. |

This is generally what I see with my machines:
----------------------------------------Intel C2D E6400 3.4GHz- 3-3.5hr per FAAH AMD Opteron 170 2.8GHz- 4-4.5hr per FAAH Naturally some are longer or shorter but the majority fall in those ranges.  |
