As Link posted a snippet of the code required. That belongs in the cc_config.xml file. Not the app_config.xml file in the project directory. Just to clarify.

But keep in mind, BOINC will then think you have that many cores and will schedule the running tasks accordingly. IE: If you have a single core processor, but use that config to tell BOINC you have two cores, then BOINC will try to run 2 tasks at the same time. Unless the tasks are multi-threaded, then it'll just think it's running two cores/threads on the single task, but physically only one core will be running.

This can be a problem in that BOINC will try to start way more tasks at once than your system can handle and will slow it down tremendously if you aren't careful. IE: Telling BOINC you have 100 cores on a 8 core CPU. 100 tasks will try to run simultaneously on that poor CPU.

It can work though, depending on the project.

I told BOINC I had 128 cores on my 12 core 24 thread Ryzen CPU so I could run YAFU work units of 32, 64 and 128 threads.
Worked well, but I was a bit slow changing it back once my goal on YAFU had been reached and BOINC flooded my computer with work from other projects thinking I had 128 cores but I only had 24.

The lucky thing about both cc_config.xml and app_config.xml files is that you can change it any time with BOINC still running then in BOINC Manager hit "Read Config Files" and it updates straight away.

Thanks Conan I had never even thought of doing it for that!! I guess I'm on my way to get some hours in a couple new apps!!

Not a problem if you're not trying to interact with it as an everyday computer.

Not sure of the advantage, unless you have tasks not using the whole core when they should be.

If it's multicore tasks, just tell them in the app_config that although they are a 12 core task, they use on average 8 cores.

Yes, good idea. I wondered who had those 128 core CPUs! Not sure what the project's desires are - how important larger ones are, maybe you should ask over there and see what they really need done. And suggest others do the same if they need the 128s done and hardly anybody has machines really that big.

Yes it is. It will cause the computer to grind to a halt and work done will be even slowly than before. Not to mention it could cause Windows or Linux to crash.

Some projects only give tasks based on the number of cores a host has. Faking the core count will allow you to download more tasks at once. Helpful if you're on a limited connection that you only want to use at certain times of the day.

Completely different.

It doesn't affect the results. Those tasks are so old and computers today are so much faster a 16 core CPU is many times faster than 64 or 128 core systems from years ago.

Nonsense, unless you tried to run a billion of them or something ridiculous. What do you think happened when we ran a few programs at once on a single core machine in the past? As long as you don't run out of RAM, there's not a problem, and Boinc limits RAM usage.

I thought the tasks were perhaps programmed to use x cores and if you didn't give them that many the program would screw up. Otherwise why are they dividing them? Just so everyone gets one which runs in a reasonable time?

Its amazing how much you think you know.

To anyone reading this. If you increase your ncpu count far beyond how many cores you actually have and do nothing else to limit the number of tasks that can run at once you'll crash your system on some projects. I am speaking from experience as I've done it, many times, mostly by accident by forgetting to change it back.

I keep a monthly electricity budget

Let me stop you there. A budget is simply a way of worrying before the event. I just wait for the bills. If something is too much, I ease off a bit.

And I refuse to save power. All they need to do is stick more wind farms up and it would be dirt cheap anyway.

Wind and solar need to store power somewhere for use over night or on low wind days.
Skeptics Guide to the Universe debates this all the time. We need nuclear still.
And we have gone through 50% of the 12 year carbon budget to avoid 1.5C average warming in 3 years since 2020.

Crypto, without actual useful work done, GPU's that are not energy efficient, these are starting to be an issue.
We do science and this electricity is well used.

But, like I said, downclocking gets the best work per Watt and I'm not going to rewire my house so I can run 6 boxes each with 4800Watt PS.
I make decision based on science and data.

All this mess (and wasting computing ressources) could have been avoided if they stopped Separation in the right time and the right way.

A month notice, not a week, as some of us only check projects on the weekends, especially during the summer.

I finished my new server and was able to grind out 15k hours of WU's by Wednesday.
Actually, running so many WU's per card, it completed more WU per day than when the GPUs were set at 8WU/card. (It has 96GB RAM compared to the 16GB in it's prior host that died during my rush and forgot to reattach the power cable to the remaining GPU. It shouldn't have died, but 2 power ons 2x GPU error beeps later the 1090T was overheating in 3 secs. RIP 1090t box... you served me so well.)
That was surprising.
In 2020, decided to only run 8 WU/card instead of 12, which got 5%-10% more RAC, but figured this subproject would go on years longer.
The 100k hours of contribution was coming too soon.

Probably said this before, but thankyou all for the Separation work.

Wind and solar need to store power somewhere for use over night or on low wind days. Skeptics Guide to the Universe debates this all the time. We need nuclear still.

If you live off grid, you can store your solar poewr in lead acid batteries and make power way cheaper than you can buy it from the grid. Also you can trade power between different countries with different current weather. Oh, like we already do. Check out the small dials on the right with country names on them. https://gridwatch.templar.co.uk/

And we have gone through 50% of the 12 year carbon budget to avoid 1.5C average warming in 3 years since 2020.

Cut the greenie crap. The climate changes naturally anyway, and I don't care what it ends up as. In fact warmer is better than colder as crops don't grow in ice ages.

But, like I said, downclocking gets the best work per Watt and I'm not going to rewire my house so I can run 6 boxes each with 4800Watt PS.

Why would you need to rewire your house? My garage already had three 3.1kW outlets. Running another wire to the garage is hardly rocket science. I can get 24kW from the mains without paying them to give me three phase.

You make this out like we have rights. We are doing the work they need done. They don't have to tell us what they're doing. If MW work stopped with zero warning, your Boinc would just download from another project, unless you're stupid enough to only have one project connected when it's unmonitored.

A 1090T is a CPU, right? I see no way a CPU could overheat by forgetting to power up a GPU. I've forgotten that billions of times, you just get no GPU showing up in the OS, and the GPU sits idling.

Tell me that you wouldn't run an Epyc 128cpu core setup if you could get one cheap enough? I most certainly would!!

EPYC 7B13 128 core, £1600 for the processor, but only 2.3 times faster than my Ryzen 9 24 core which is £300. Not cost effective.

I have a few of them.

Are you sure they're yours or are you borrowing them from your boss when he isn't looking and using his electricity? Because you've chosen to keep them anonymous, funny that.

hiding his hosts wouldn't hide anything from his hypothetical "boss". he doesn't even work in the tech industry. so yeah, wrong again.

i have five 64c/128t CPUs, and two 48c/96t , wholly owned by me. they're cheap. don't need to use other people's computers. EPYC's are ubiquitous at this point. The whole platform cost isn't much more expensive than high end consumer stuff, but without the silly caps in PCIe lanes and core counts. density and performance per watt goes to the EPYCs
