The FUH on the server is reporting that it's out of disk space.


Is this something that will not be fixed until tomorrow due to timezone? I am trying to figure out if I should just wait, or fire up some other project until this is fixed.


Timezones work to our advantage in this case, as the sun will be coming on on stream in an hour or two.

It will be interesting to see which happens first: we finish the DC or Elon Musk successfully lands something on Mars. Not a person, but any sort of lander.

As for predictions, I think you're in the right ballpark.


Was looking through old posts, and of course we finished it earlier than Elon Musk :P

Also,
Understand that both Jim and myself are really paranoid about business continuity, and it's hard to imagine any sort of disaster that would result in the data being lost. I can think of things that would shut PrimeGrid down permanently, but the data would survive such an event. I might need to use sneakernet to distribute the data (the proverbial station wagon filled with 9-track tapes), but short of a nuclear holocaust hitting multiple locations, the data is well preserved. And if there's s single event that takes out both the data center and the secondary storage site, which is hundreds of miles away, I suspect what's left of civilization won't be worrying about our data.

What would shut down PG permanently? Just asking.


Rytis dies of Covid-19? Everyone gets bored and stops crunching? All the admins get tired and nobody else wants to do it? World War III? Economic disruption from the pandemic is so bad that we can't afford to keep the project running?

The USUAL things that kill a project are either "disk crashed and I lost all the data", or "server died and I can't afford to replace it." Those are not things most hobbyists plan for (or even most University-run projects). PrimeGrid's pretty well protected against that kind of failure.

Not 50*** , I am still getting those.
When might we find out which base was prime and how found it?


Looking at the tasks I've gotten in the last day or two, it's either 68633 or 76877, and most likely 68633.

I have lots of the tasks for the other 4 k's with n's near the leading edge. 76877 highest n is about 3.0M, but I only have recent double check tasks for 68633 around 2.6 or 2.7M. So 68633 seems like the best bet.

Does LLR2 use AVX-512 if available?


Yup.

I believe it also has a switch to turn off AVX-512 for those with "special" CPUs.

Run BOINC instead of PRPNet. Every task there gets validated.


I will do that, I have been running BOINC for two decades. I figured I could help out here as well, but it appears it is easier for me to go away than to contribute with some help from others. You are not the first person to imply that I should go away.


I don't recall anyone, especially me, saying you should go away. I said you should run tasks from our BOINC server instead of the PRPNet server. Running a known unreliable host on PRPNet, where errors won't be caught, creates errors in our data. On the BOINC server, the errors will be caught and corrected automatically.

More importantly -- for you -- you asked how you could tell if your computer is running reliably, and the literal answer to your question is that you should be running tasks on our BOINC server instead of our PRPNet server. Every task run on our BOINC server is also run by a second computer, so you get feedback on every task you run telling you whether your computer produced the correct result.


Sorry, been a rough day...I was out of line.


No problem. You're in good company -- there's about 7 billion of us who have been having a LOT of bad days lately.

I call it "Covid brain" everyone is more stressed out and on edge than normal.

I have been informed that my machine has produced bad results. I have a failing CPU cooler and the replacement is on order. This failing unit has caused the machine to force restart several times recently and I wonder if that would cause errors in the PRP clients. It was my understanding that it would just resume from prior checkpoint, is that not true? How do I track down the source of errors, I would like to still run PRPnet but do not want to produce bad data. Any suggestions would be appreciated.

Thanks,
Greg


That's possible, but the more likely answer is that the CPU was malfunctioning because it was overheating.

If it's overclocked, that's even more likely to be the cause of the errors.



It is not overclocked but with 32 cores, it runs hot! Is there anyway to validate jobs as a user? I can back off the number of clients until new cooler arrives but I have no insight as to quality of computation.....
