my laptop appears to suspend tasks (cpu busy) after about 3 minutes and then I have to move the mouse to get back into running mode. what's up with that? I check my laptop power and sleep settings and they appear to be in high performance mode ---- meaning I am not have the laptop shut anything down or go into some power saver mode. Jedeeze can anybody help on this one? Please. I have a DELL Inspiron 15 3537, dual core with 12GB ram. Usage of ram is only 3.1GB My desktop is cruising along fine. No problems |

I think I discovered the problem and the solution: My desktop has 4 cores and runs at 3.3GHZ, running 4 threads. RAM = 12GB. The setting in BOINC computing preferences for non-BOINC CPU is at 35%. GPU is OFF. All is good and I have never had a problem. My laptop only has 2 cores but is running 4 threads at 1.7GHZ. RAM = 12GB. The setting in BOINC computing preferences is set at 25% for non-BOINC CPU usage. GPU is OFF. Since I have only 2 cores, I set the non-BOINC usgae needed to be raised to 40%. And this my friends has appeared to have solved the problem of my laptop suspending tasks indefinitely. There are other tasks running that need CPU time and raising the non-BOINC usgae from 25% to 40% appears to have fixed my problem. |

I always set the "suspend when non-BOINC usage is above" (or whatever the setting is called) to 0. The CPU and OS can handle the scheduling of tasks just fine and I find that setting overly conservative for most computers. D |

I too set this "limit" to 0. Maybe I'm wrong (I mean the setting is there for a reason), but I'd imagine that reading the CPU usage and suspending and then resuming the task takes time/CPU cycles necessarily. Letting it run alone in low priority would simply make the application itself back off in favor of normal priority tasks... IMO, BOINC doesn't doesn't affect my PC performance at all (except playing CPU intensive apps or games where every CPU cycle counts). I think the biggest "burden"of running R@H on a PC is the RAM usage. But if you have 2+ GB per core, then running Rosetta shouldn't interfere with normal PC operations. As a matter of fact, the only way I can "tell" BOINC is suspended (without looking at the manager of course) is by listening closely to my laptop fan. If it's too quiet (it has two BIG fans) then it's because GPUGrid and Rosie are suspended. This is different for old and slow computers that tho. OP should be able to run Rosie at "0" without problems. |

(it has two BIG fans) then it's because GPUGrid and Rosie are suspended. What model of notebook is that? Looks like a beast and I'm in the market for a new development grade laptop. PS - your RAC is through the roof these days (I suspect due to those cloud trials).. Here I thought I was slowly catching up to you :P |

My laptop is an old Asus ROG G55VW (about 3-4 years old) 15 inch screen (this host) i7 3610QM + nvidia GTX 660M GPU. I have it running vLHC on two threads, and Rosetta on 6. GPUGrid on the GPU. It pulls almost 3K for Rosetta and 1K for vLHC. It has been under this stress ever since I got it... and it still works flawlessly. It does get hot during the summer when running both GPU and CPU (the CPU is cooking at 90C right now). It drops down to 78-80 during winter. It lives as if it were the last. There are newer models out there, like the G752. Most new laptops are 17 inches though. So they are really a desktop replacement laptop. You should see the size of the transformer/power supply of these things... HUGE. lol Fast and impressive cooling, but... big and heavy. There's even a water cooled laptop from Asus. |
