Oh my god, where did you get all those Ryzens from? That's pure pornography!

I just happened to spend the winter expanding my fleet. They came online just in time for the coronavirus.
I also do Folding on each one too - which just recently announced a project for it.

But they are really to heat my basement. You might as well have fun at the same time.

I think you're considerably richer than me. I'm using 2nd hand GPUs and old computers I've been given. And wondering how I'm going to pay the electric bill.

I think you're considerably richer than me.

You need to check out a fellow named Doneske on WCG. He has a real layout.
Though unfortunately you can not see it directly. But he mentions it once in a while, and you can infer it.

This is interesting. After being stuck for 12 hours, BOINC is willing to download new Rosetta work units.
It is perhaps not coincidental that I have it set to run the 12-hour work units. Apparently all the old ones have to finish.

The ones that are stuck still remain stuck (four of the 4.08 Rosetta rb_03_01_17261_17076_ab_t000__robetta_cstwt_5.0_IGNORE_THE_REST), but at least you get new ones.
So you could set a backup project (zero resource share) to fill in the cores as they go empty, and get back to Rosetta automatically.
You then only have to delete the stuck ones at your convenience, but they do not tie up the entire machine.

I always have more than one project for a processor, as I hate things sitting idle. Either I give them weights to relate to how important I think they are, or I set one to priority 0 so it only runs when the other isn't working.

What's annoying me just now is I have most of my processors assisting GPUs for Milkyway and Einstein, so Rosetta doesn't have many spare cores to work with. I want one of those 64 core Ryzen threadrippers.

It's a pity Rosetta won't run on GPUs, but I guess it depends on the calculations involved.

Save some money and still get a big boost.
https://www.amazon.com/AMD-Ryzen-3900X-24-Thread-Processor/dp/B07SXMZLP9/ref=sr_1_3

I expect that sales are off due to the virus, so prices are coming down a bit.
We can use the virus to fight the virus.

By the way, I would rather have two of the smaller chips than a Threadripper. You have to feed it with memory, cool it, and buy expensive motherboards. Besides, a lot of projects can't use all those cores. You just buy into trouble.

£400 or £3700, ok I didn't realise they cost THAT much!

And surely any project can use all those cores, you just run many WUs at once? Rosetta for example is single core, yet it runs on multi core chips just fine, just several at once.

The good thing about absurd chips like the threadripper is it makes the others cheaper. Same with cars, the posh folk buy new cars then I get their old ones cheaper.

---

There are limits in BOINC (somewhere), there are limits in VirtualBox, there are limits all over the place.
You will find them when you get to them.

Threadrippers are really for servers, where space is at a premium. Also, they have cache limitations that you avoid with the smaller chips. I think the latter are more for our use.
I even use the micro-ATX motherboards, since I have dedicated machines and don't need the other stuff. They are cheap and stable, since I never overclock (Just don't get the cheapest. They leave out the heatsinks on the voltage regulators.)

Are you saying you can't get Boinc to run 64 cores? I'm sure I've seen somebody doing so successfully.

At the current prices, definitely.

I seldom buy boards, I tend to collect donated stuff and have fun cobbling it together. Only thing I've bought is GPUs, and those were second hand or broken.

I don't know where the limits are, but I have seen reports of problems in various places.

Sounds like a CPU (memory access) problem rather than a Boinc problem:
https://setiathome.berkeley.edu/forum_thread.php?id=83824&sort_style=6&start=0

---

That speed problem may have to do with cache access. As I recall, the Threadrippers access it differently than the Ryzens, since they are intended more for server use.

---

Here is another curiosity. I saw a download start and then hang up for two work units. So I immediately did a "retry all", and it worked.
So there is something about the time delay that causes them to stay stuck?

Yes, I see a whole bunch of them too (on seven machines).
They are mostly rb_03, but a few others too.

You would think it would be easy for them to track them down.

---

I am getting small stuck downloads that stop the client from getting any work. Was hoping to see a solution here, but there doesn't seem to be one. Am discontinuing participation until this is fixed.

I have tried many times to get it to work, but I am being forced to take machines off of Rosetta as they get stuck.
They will go back to where they were. You can't fight the coronavirus if they don't send you the work.

This is odd, as I've not had any stuck ones for over a fortnight on 4 different computers. There must be a reason they fixed it for me and not you :-) It just suddenly started working, before then every machine stuck once a day. I don't think I changed anything that would have fixed it.

Yep, got a bunch of stuck downloads on all of my computers today too.

In addition to files from rb_03_08_ tasks already reported above there were few tasks like this:

10/03/2020 23:53:17 | Rosetta@home | Temporarily failed download of twc_method_msd_cpp_10v4nme2_1719_result_0965_msd.zip: transient HTTP error

It getting really annoying, this bug repeats every few days for at least a month already.
Next time i probable just switch my computers to WCG from R@H.

P.S.
Looks like aborting whole WUs with stalled downloads instead of aborting download itself (internet transfer) is a faster/easier way to clear such errors.
BOINC resume work fetch almost immediately after WU abort while after aborting download it usually still refuses to get new work for few more hours (complaining about stalled downloads even after all of it already aborted) or until BOINC restart.

This is odd, as I've not had any stuck ones for over a fortnight on 4 different computers. There must be a reason they fixed it for me and not you :-) It just suddenly started working, before then every machine stuck once a day. I don't think I changed anything that would have fixed it.

I have seen that too. I wonder if it is determined by the number of machines (that is, cores) you have on Rosetta?
As I go down, I will see. It could be that their server chokes up, but would be surprised if it starts working permanently.

Several stuck downloads recently. Here's one on on Ubuntu 19.10. The offending file is

twc_method_msd_cpp_c3212_9mer_gb_000182_msd.zip (workunit 1014896837)
