Hi,
In future client version would it be possiable to allow custom CPU percentage limits. As I would like to use 100% CPU after hours and limit CPU usage during businees hours to 90%. The current client allows customised CPU start and finish times, but cannot limit the CPU percentage within these custom times to different levels. This would allow more work units to be processed after hours when resources are available but limiting to 90% CPU during work hours some computers are actually usable. Regards Paul |

There is no point.
CPU use is already at the lowest possible priority. The CPU throttle is to prevent laptops from overheating, not to make computers "usable". If your computers aren't usable with BOINC running, then you have some other problem. |

also, anyway, you cant load 90% (or other fraction) of CPU. 90% of time it works at 100%, and other 10% of time it works at 0%.

Personally I see some benefit in that idle/use percent feature for those that are running more intense applications where for instance rendering is affected, gaming etc. Yes, you can now cause BOINC to fully pause when specified applications are loaded, but if they need 50%, why waste the other 50%... though on quads and up and tools to use affinity control I doubt the need is still there.
----------------------------------------As for the temperature control function, BOINC 6.6 works as pathetic as 5.10 and 6.2 causing a perpetual on/off at whole seconds level. My suggestion for those having that 'problem' to deal with is to use the TThrottle utility, a volunteer designed specifically for BOINC science control of CPU time against a target temperature. Works now permanently on my XP laptop. All windows versions

Sekerob, you have good advice about how to smoothly throttle BOINC, but it still makes no sense from a usability point of view.
CPU is not the bottleneck. CPU is an on-demand resource, and BOINC only gets the spare cycles. Memory can be a bottleneck. But as rilian says, even if CPU throttling could make a difference, the way it is implemented in BOINC rules it out entirely. |

Is the "perpetual on/off at whole seconds level" emphasis saying something different to what rillian says? Never mind.
