Message 99695 - Posted: 16 Nov 2020, 23:35:54 UTC

I wondered why my 1GB of memory RPi3B+ was frozen for a day and only showing 3% cpu utilization. Found out it was trying to crunch a horns task. Aborted it just as soon as I looked at the name of the task. Much better now.

There's a fresh batch of Horns tasks that have been released.
Currently running Tasks are 2.7GB, 3.1GB, 3.2GB, 2.9GB and 2.8GB in size (at present time). 20GB of RAM in use.

Yes, I have a bunch of them around 4 GB. It must be an interesting new project, but more fun if we knew what it was.

- Maybe the possibility to choose apps in user's profile.
- It's time to drop support to 32bit OS

At the moment, I have 69 Ryzen 3000 cores on Rosetta (Ubuntu 18.04.5). 15 of the work units are Horns, or about 21%.
They are all large, around 4 GB. So the project is still in the early phases. They will shrink in a few days.

Just be careful as they take alot of memory and running ie 24 of them on a Threadripper can quickly run out of memory.
Nothing compared to CMS from LHC - 2GB each. And if you buy a threadripper, surely you also buy lots of RAM?

WCG ARP units can get upwards of about 3/4 of a Gigabyte when they're fresh, possibly closer to a Gig at points. So it's not too much for most modern systems to handle, but it's enough that most people probably wouldn't want more than one. Rosetta units do tend to stay pretty steadily in the lower hundreds of Megabytes. It's just a question of knowing how much RAM you have and whether or not you tend to need RAM for a lot of other things.
I always have 1.5 to 2GB per core in a machine, unless it's one made out of scrap parts. My Aunt bought a laptop from PC World recently with only 4GB in it, and not upgradable! Even with an SSD it was unusable, and all she does is Word processing and emailing and sorting a few photos. PC World apologized and gave her a full refund. She's going elsewhere to someone who has a clue.

At the moment. There have been times when most of them were around 1GB, with some around 3GB.
Allowing 1.3GB of RAM per Task means you won't run in to RAM issues even when there are lots of high RAM usage Tasks being run. If you've got less than 1GB of RAM per Task then you will run in to a lack of RAM issue at some point.
Boinc does have a "use only x% of memory" option, use that. Although I often put mine to 100%, since it allocates more than it needs, I've seen it say it's run out when it's set to 80%, and only 55% is in use, including Windows itself.

horns tasks in the current batch running around 4 GB each [example]

Yes, I have several. The biggest is 4.4 GB, the largest Rosetta WU I have ever seen.
Just went through my list of Valids and found one over 5GB.
I think 2GB was the smallest.
This is starting to sound like a David Attenborough program.

Yeah, it would be nice to know.
Sometimes, you can tell what it is about.

COVID is COVID, MERS is coronavirus as well, VEGF seemed to have something to do with blood vessels, etc
CTLA4, I believe I saw COVID on a result log the other day.

But horns, I can't even attempt to guess what it may be lol
Viagra research :-) I much prefer being able to choose which research I do, like I can in WCG.

The problem has always been they want us to crunch ALL the tasks not just the ones we think we like, if they did something like WCG or PrimeGrid does with the different sub-projects then yes it would work but it's not like they have alot of tasks to begin with so splitting the project wouldn't be ideal right now.
I'm sure most folk at least leave the "other apps if no work is available" box ticked.

I wondered why my 1GB of memory RPi3B+ was frozen for a day and only showing 3% cpu utilization. Found out it was trying to crunch a horns task. Aborted it just as soon as I looked at the name of the task. Much better now.
I've got a 0.5GB phone, it doesn't even attempt Rosetta any more. The project tab shows a complaint in a yellow box that there's not enough memory. It's pretty much limited to Universe and Einstein Radio Pulsar.

Send them here, I'll do 5 at a time. I've just ordered an MSI pro gaming motherboard and a Ryzen 9. The board will take 128GB.

I've only ordered one 32GB RAM stick for it. Yeah I know, it's faster in pairs, but this way I can go up to 128GB without having unused RAM to take out. My main computer is currently 6 cores with 16GB, and occasionally I want a bit more RAM if it's running LHC tasks. The Ryzen is 24 cores, so I might find I run out of RAM in Boinc easily, so I'll make it 64GB, and possibly 128GB in the future. I also love huge RAM for huge disk cache, but probably not needed with NVME disks (which I won't have yet, I've still got a SATA 3 SSD which I'm moving across). I wonder if Windows 10 will let me just shift the SSD over or if I'll get BSODs like the older Windowses used to do in panic with a new motherboard? I really don't want to have to reinstall 100s of applications.

Do some searching on the net, some people say that if you remove all the motherboard drivers and then move the drive over to the new motherboard Windows will auto load the new MB drivers never thinking anything has changed, I have NEVER tried this on my own so have no personal knowledge if this really works or not. For me the key is to do a REALLY REALLY good backup before you do ANYTHING so if things don't work you can always go back to where you are. Another thing I saw says in some cases you can port Windows over to a new system IF you have the right kind of Windows, ie no manufacturer installed versions work, one of my installations says it will do that but I'm not moving anything right now.

it should be possible since win10. maybe it tries to boot twice to recognise the new mb.

It has never worked for me with Win7. I always ended up doing a clean install. But I looked around and found this, though I have not tried it myself.

I backup monthly using a direct clone of both disks (I have an SSD system disk, and a rotary drive for large stuff like films and TV). I ran one of those backups first, then searched on the net and the only caution was about the license getting damaged, which I'm not concerned about for two reasons, one of which is you can just phone Microsoft as long as it doesn't happen too often. I then cloned the system disk to a spare disk, shoved that in the new machine and it very quickly automatically installed the drivers and behaved as if nothing had changed. So I discarded that drive and shoved the real drives across. Works perfectly. The only thing that didn't work was overclocking. I don't know why I bothered trying, I've never had success in the past. I tried 3 things: 1) speed up the main bus, from 100MHz to 110MHz. Couldn't even boot into the BIOS, had to reset the CMOS with the button on the motherboard. 2) change the multiplier. By default it auto varies anywhere between 3.8GHz and 4.7GHz depending on the temperature and how many cores you're using. When trying to overclock it, I changed it from "Auto 3.8" to "3.9". This resulted in it being 3.9 all the time, so slower! I thought about forcing it higher by that method, but thought perhaps I'd remove the safety catch of overheating and slowing down, plus it's probably able to go fast for different numbers of cores so removing that ability is counter productive. 3) "Game boost" in the BIOS, which should do it automatically. It made zero difference to running 1, 4, 8, 12, or 24 Boinc tasks at once. Things may be complicated by me only having one (32GB) RAM stick, so single channel. I did that so I have more room to upgrade in the future. It'll get a second one at some point, and maybe one day a 3rd and a 4th.

Well they've finally fixed it with Windows 10. Like you, I got terrible things happening with 7 and earlier, usually a fatal exception error and not even possible to repair the installation from the DVD. but this one worked seamlessly, and I was changing drastically, from an Intel to an AMD system, so completely different drivers for everything. I think the main problem used to be Windows not having the driver for the SATA controller, so it couldn't access itself. But I think that's more standardised nowadays - Windows 10 just calls all mine "Standard SATA AHCI controller". The only exception is the old DDR2 system. All 6 of the DDR3 and DDR4 era machines say "Standard SATA AHCI controller". I bet you when I put NVME stuff in, the Brahmin excrement hits the fan again.

Very nice. I will be upgrading to Win 10 shortly, and that will be of some use at some point, though it will be a clean install at first. Thanks.

It happens alot for people with slower connections due to the lage even you see when posting being sooooo long. It also happens with fumble fingers.
