No, 19V.

Well you did say "mobile-PC" not "truck".

Are you building a new computer for yourself?

Yes, a 24 core Xeon system. It will run the Rosetta Coronavirus
research program, and when that's done, something else in biology or
physics.

In hindsight, it would have been cheaper to buy a crap version of the
server and upgrade a few parts. I've had to get some difficult to find
brackets and adapters, like these:

That's a very noble thing to be doing. THANK YOU.

I was already doing it for fun and to help out astrophysics projects, I added Rosetta to the mix when the virus appeared. You can set up Boinc with as many projects as you wish and alter the priority of each.

It's a pity these projects don't hand out money (to at least cover the cost of electricity), then I think they'd get 10 times as many people doing it. They already have a brilliant system so you can see how much work you've done, and if you're doing better than others, so it would be easy to apply a small amount of money to that.

I'll have a study here and see what I could do personally to help:-

I believe the program will run on any CPU under Windows, MacOS, or Linux. If you have a good graphics card, you should go for Folding at home instead, as it can use that too.

Even mobile phones running android can run Rosetta. Not sure what you can run on Iphones.

I would use that if Boinc had nothing useful for me to do, but I've been with Boinc since it started a couple of decades ago. Nicer to have all the projects in one place.

Does folding at home do biology research on graphics cards? Boinc only has physics on the graphics cards.

Can you see in Boinc what speed it says about your CPU? Tools menu, run CPU benchmarks. Then go to tools, event log. I get this on one of mine:

Mon, 27/4/2020 08:16:42 PM | | Number of CPUs: 6

I'm wondering if that wastes computing power that could be doing the calculations faster.

Why are you running it on the old one? Newer machines can do it faster.

I don't know - but I suspect that it DOES 'waste' computing power.

Wow, that's old. 65nm die. They're now down to about 8nm.

I'm surprised it runs Rosetta so quickly though, it thoroughly beats my Q8400 which is the next level up, although mine is a 4 core so it does twice as many things although at half the speed. I have noticed some projects run better on some CPUs and some better on others - I guess they keep changing the instruction sets and altering what they're best at. Graphics cards are even worse - I deliberately bought some that are several years old, because they're really fast at high precision calculations, which they've all but removed from the newer ones. But it's what the Milkyway project needs. But not what games need, which is what most are marketed at.

It is when they have 11 million of those tasks queued. There are 34,000 people currently running the project, which will get through the queue in a week, but they keep adding to the queue....

Apparently since the Corona virus appeared, they've quadrupled the number of people running it. They've been around for ages doing biology research into cancers etc.

> I like to keep my 'best' computer for day to day computing! ;-)

And you can. Rosetta doesn't slow things down, except for some games that need the computer's full attention. It normally gets out of the way of day to day stuff automatically, the program is set to "low priority" in the operating system. I let all mine process science 24/7. The one I use has a couple of "exceptions" in Boinc to pause computation if two specific programs are running (both games). You can even tell it to pause computation whenever you use it (i.e. as soon as it detects you moving the mouse or pressing a key).
