I have an I7 920, and task manager says that all 8 threads are working at 100%, yet there is no(or hardly any) difference in using my computer while BOINC is at full throttle. It seems like is BOINC isn't fully untilizing all the power or else things would be lagging and such when CPU usuage is at 100%. I'm not talking about playing games, but how is normal web browsing and opening small programs not any slower with cpu at 100%? Is it because of the extra RAM I have available?

BOINC is working exactly as designed ... it runs at a very low priority so whenever you want to do something it steps aside precisely aso you won't notice something else is going on. Most people would hate seeing a lag and uninstall BOINC and we would never get anything done. As long as you have it using all cores at 100% you are getting quite a lot done on that snazzy 920.

You don't notice, most of the time. There are features in BOINC and some nifty 3rd party process control tools that allow you reduce the CPU time allocated to BOINC if you do notice (gamers do e.g.).
----------------------------------------A good way to see the result can be found in a 3rd party tool called BoincTasks. It has a CPU % column, reporting the full run time efficiency. At night the jobs reach 99.99% efficiency on 3 of the 4 cores of my quad... the Core 0 is also used by the system, so that one shows about 98.5%. But, during the daytime when using the system, some multithreaded stuff, I see 95/96%. BoincTasks is also very good at logging completed tasks, show the actual CPU time and Wallclock time used by a job, so it visible how much of the time was not going to a BOINC science. For example a RICE job of last night lists 7:03:17 (7.02.23), meaning 54 seconds went somewhere else. From yesterday a RICE job lists 7:17:17 (7:00:17), meaning 17 minutes were used by what the system and I were doing... 96% efficiency. Personally I think most of the lag seen occurs from sciences loading and unloading when they have large work files. I run with the Leave Application In Memory when pre-empted (LAIM) on, so a job is always ready to resume instantaneously and lossless. Which I920 does not have enough RAM to do this? Happy, I don't notice, crunching (what better advert can we get ;>)

I'll have to check that program out. I understand BOINC is designed to not use resources while the computer is in use, but my I920 is rarely used (I usually use my laptop) and I was just making sure that I was maximizing its potential (both while in use and not in use)

With regards to "while not in use" you might make sure that your operating system is not switching your processor down to the energy saving mode. Look for "power management".
----------------------------------------For "when in use", after making sure that you have chosen "use 100 % of processors" and "use at most 100 % of CPU time", from the Advanced view select Activity and "Run always". Next, quietly enjoy the power of your machine which makes you think that you are alone using it while, in fact, applications controlled by BOINC are computing like mad.  Cheers. Jean. |
