suspended - cpu busy

Topic 197256
(moderation:
Hi guys, yesterday evening i got this message, for every project. I run Einstein@home, fightmalaria and another one. Everything worked fine untill yesterday, when it said "Suspended - CPU is busy".
I set it to use 90% and it can also use the Nvidia card.
I don't have too many other applications open, so it's quite ackward to have this message.
Still, I can hear something is working, because proc. is between 50 and 100% and can be heard working (the noise).
Another fact: the size of a project hasn't changed: it has 280.000gflops, 100.800, and so on. And I guess 99% of the ones solved were the same. So why suddently - cpu is busy?
pls help!

Probably some other program is using all the cpu time, to find out what program open windows task manager (Ctrl+Alt+Esc) and then click to show more info and check out the process tab. When you have identified the process you could then decide if it's a program you want to run or if it can be shut down. Google is your friend if you don't know what process belongs to what program and if it's an important program that's necessary for the correct function of your system.
If you don't want Boinc to suspend work even though something else is making heavy use of the cpu then go to your computing preference and change "Suspend work if CPU usage is above xx%" and set it to 0 (zero) to disable this function.
I've just checked the tasks

I've just checked the tasks (from the computer, not boinc) andI have none which uses a lot of cpu power or any ram. I have ran boinc for about 48 hours non stop on a ASUS laptop. Is it possible to have "burned" the video card? :) About one day long it was set to use 90% of the cpu, and after that I switched it to 50%.
RE: Is it possible to have
)
Possible yes, probable no. Both CPUs and GPUs reduce their speed if they get to hot to protect themselves so it's unlikely that it's burned.
Just to make it clear witch setting are you talking about?
Is it
1. "Suspend work if CPU usage is above xx%" or
2. "Use at most xx% of CPU time" or
3. "On multiprocessors, use at most xx% of the processors"?
The first one sets Boinc to pause work if anything else on the computer uses the CPU more than the set number and the second one has the effect that Boinc pauses and resumes tasks to make it appear to use the set amount of CPU time and the third limits how many of the CPU cores Boinc can use.
first one = 0, so it means go
)
first one = 0, so it means go on for ever.
second & third = 50% (now).
It was ok, i just did a restart and now it's going fine.
But, as general guidelines, how would such a task ( a distrib. comp. project) be handled responsably 1 - for a laptop and 2 - for a desktop. I know these projects were set initially for supercomputers, not home/office desktops or laptops. So, in order not to burn/destroy/overheat/etc such a computer, how should such a project be run wisely?
Usually, a desktop is used about 8-9 hours/day and then is turned off. So, during these hours, would it be ok to run Boinc projects at about 25-50% of the CPU power? And also for a home laptop (even if it's powerfull), would it be ok to let it run Boinc during the night?
Not advising, recommending,

Not advising, recommending, suggesting or anything like that, but I use my big old desktop 24/7 unless there's lightening. Trust me, nothing about me or my computer is super. I let the Einstein people set up my usage and they haven't steered me wrong yet.
(PS Sorry Mods, for butting in)
The main thing to consider is
)
The main thing to consider is cooling, keep the machine as cool as possible. For a desktop that means that more and bigger fans is almost always better. For a laptop it could be a good idea to put something under it's "feet" to raise it up a bit more from the surface to allow more air underneath it where the air intake usually is. Download a program to monitor the temp, I use Core Temp to monitor my CPU and GPU-Z to check out the GPU. As long as the temp is kept under check there should be no problem to run at full load all the time.
Keeping them clean applies to both a desktop and a laptop although the laptop can be more challenging as it's usually not easy to clean the fan and cooler. But once in a while gently blowing some compressed air into the air outlet while having something inserted to keep the fan from spinning out of control can help a lot.
I have a desktop running Boinc and mainly Einstein 24/7 on all cores and 100% of the time and have done so for the last 10 years or so, during this time I've lost one PSU due to bulging capacitor and one GPU, the graphics card was under warranty and replaced without any fuzz. Normally when I build a new system I aim for it to last about 5 years before I upgrade again, possibly changing the graphics card once in that lifespan.
Thank you Holmis for these

Thank you Holmis for these tips. I got both programs, they're very good. I also use Open Hardwae Monitor, which is a combinatin of these two. If cooling is the main problem, then that's not such a big problem. A cooling pad (for laptops) at about 40-50$ should do it's job, I guess.
