If you need to heat your home, it does not matter whether the watts are converted by a kilowatt electric heater or a kilowatt of computers - the same amount of energy is consumed from the electricity source and converted into the same amount of heat in your home. The difference is that computers also produce data in the process. If heat is needed, one can argue that energy converted into heat computing WCG is more responsible that the same amount of energy simply converted into the same amount of heat.

Sure, let's continue in simple English. Regarding electricity - experts recommend using it as usual. If I'm not mistaken, reducing consumption leads to energy waste.
In my specific case, I was interested in whether it's worth crunching WCG or installing something from other distributed projects. What could my computer calculate and send in three hours? Can anyone give some advice? Maybe someone knows what can be calculated and sent in two or three hours. Finally, expert opinions and large-scale solutions are appreciated. For example, if you figure out that the sum of Ukrainian users' crunching isn't so important for the world balance, you can temporarily turn off WCG in my country from your side by writing about it on your page. Provide a causal-consequential chain example for logical awareness. Turning off electricity in grain storage can lead to mold growth on cereals, some of which contain toxins that increase the likelihood of cancer in the future. Is it worth doing anything to reduce energy waste, such as the energy used by WCG in Ukraine, which leads to electricity shortages, like not being able to boil water or causing health problems? Should WCG and other distribution projects be focused on reducing the consequences? Do you understand? Something else could become a priority in changing the current situation. For example, if you went to lunch in the winter, the food was your priority at the time, and then you slipped and hurt yourself. Would you continue to lunch or go see a doctor? Sorry if the example is unpleasant. Здоровля(с)! |

Not knowing the power of these machines, it's hard to say how long a WU would take. You can tell us. How long do the tasks say they will last in Boinc Manager? How many in your queue right now. Are the deadlines far away or close. If too many then reduce the queue length.
----------------------------------------So do projects which are short. NO ARPS in your profiles. I would keep my checkpoint to a short period. This way when the power cuts out and then comes back in again you would only lose the time from the last checkpoint. Mine are at 600 seconds at most. I seem to remember that I increased it from the default. Don't remember what the default was. That checkpoint option is in the Boinc Manager under Options/Computing preferences. You can see the checkpoints in Boinc Manager logs by turning it on in Options/Event Log Options and select checkpoint_debug. You will have to figure that out from your stats. How many aborted due to time. You mention Intel i3 and AMD E1. Exactly which CPUs just to see if they are comparable to something I have and then I can estimate times. Windows or Linux? I still have the same opinions but will stop the preaching and concentrate on getting something done because that is what you want. [Edit 6 times, last edit by BobbyB at Jan 30, 2023 4:13:33 PM] |

I checked and 600 gives me checkpoints at 10 minute intervals so 300 will give you 5 minute intervals so at most you can lose 5 minutes * number of WUs running on all machines. On average this would be 2.5 minutes.
I had an ARP WU loaded on a slow PC (i5 M 520 @ 2.40GHz) and it lasted 1.5 days at 24/7. With your 3 hours on/off this means 3 days which is why I said no ARPs. |

In my specific case, I was interested in whether it's worth crunching WCG or installing something from other distributed projects. With CPU-only machines, WCG is a good choice IMHO. Stick to MCM, it checkpoints every 10 minutes (even if you set something lower than that), so not much work will be lost in case of power outage.I checked and 600 gives me checkpoints at 10 minute intervals so 300 will give you 5 minute intervals so at most you can lose 5 minutes * number of WUs running on all machines.
