11) Message boards : Number crunching : WW testing (Message 144608)
Posted 4 days ago by Profile Michael GoetzProject donor
Can you estimate a rough timeline? Will it first be available in PSA or go straight to PG?


The major change to the software, at least one of the major changes, is to allow WW to run on BOINC. It used to run on PRPNet. So it's going to be a BOINC project. Timing is "as soon as it's ready".

When I first got the 3700X the temperatures were crazy, with it going into the 90s at times and showing higher temperatures when I was running *fewer* cores. It was clear that the included stock cooler, pretty as it is, was woefully inadequate.

My old Noctua needed a different mounting system for this MB, so I was considering all options. AOI looked enticing, but it wouldn't fit well in this case, so that caused other problems.

Adding some additional case fans plus understanding that the CPU actually runs cooler when fully loaded helped with the temperatures. Even with just the Wraith cooler, it was usually in the 70s with the fans full up.

Turning off boost dropped the temperature to 61. Big difference. It's running at a steady 3.6 GHz now instead of 4.0-4.2.
13) Message boards : Problems and Help : LLR2 task validation error but no Gerbicz error? (Message 144577)
Posted 4 days ago by Profile Michael GoetzProject donor
It can happen, but it's rare. The Gerbicz error checking can't catch errors at the very end of the calculation.

I see that this computer has had several tasks completely fail before the tasks were completed. I suspect whatever caused those tasks to fail was also responsible for this error.

in particular AMD Zen2 CPUs (Ryzen 3xxx) out of the box tend to be a bit too aggressive with Boost frequencies and voltages. Several have us have simply turned off Boost in the BIOS, or at least dialed it back a little bit.

Maybe I missed the discussion, is there is a summary of how this conclusion was reached?


My system with the warnings is a recent rebuild. It is a launch day 3700X, in a B450 ITX mobo so not the best combination there. I do have a Noctua D15 so air cooling doesn't get much better, and haven't yet touched ram speeds so it is still only at 2400.

I did try lowering the power limit, which amusingly is done by going into the "overclocking" section of bios. I've had bad experiences with Ryzen Master so I wont be installing that. I did note Spread Spectrum was on so I turned that off. This is a small frequency variation in an attempt to lower peak interference generation, but at times it is in effect a slight overclock balanced out by a slight underclock at other times. Anyway, first reboot afterwards: I get a BSOD on starting BOINC. Not good... I've restored the power limit to stock, so only setting change is Spread Spectrum disabled, and will see if that helps in itself.


Summary of the Discord discussion:

Honza: One of my teammates is seeing some Gerbicz errors.

Me: Let me go search the database to see how many computers are affected.
Me: Hey, Honza, two of your computers are on the list too!
Me: Holy crap, so is my new 3700X Uh oh...

Someone then mentioned that the Zen 2's were notorious for running at the edge of stability right out of the box. It might have been tng who said that, but I'm not sure. After soom poking around in the BIOS, I decided that the part that I understood best was turning Boost off. That completely eliminated the Gerbicz errors, reduced both power consumption and temperatures, and seems to have also eliminated a very infrequent system crash that had no obvious cause.

I'm fairly confident I can turn boost back on and just lower some clocks or voltages, but I haven't gotten around to tweaking the settings. For now I have Boost off. Temps are in the 60s -- with the stock Wraith Prism.

Good to see I'm not on that list.
My 3950X runs at stock. I don't use the boost settings in the BIOS. I figured running BOINC 24/7 at stock was harsh enough :)
Running 8 tasks is currently clocking at 4.0Ghz.


Boost IS stock. Unless you modified the BIOS settings, Boost is turned on.

3.5 GHz is the base clock speed for the 3950X. Boost is raising it to 4.0.

This is a list of all computers that have had a Gerbicz error detected in their challenge PPS-DIV tests. If you're on this list, the listed computer is malfunctioning. We advise correcting the problem. Even brand new, un-modified, not overclocked computers may appear on this list. Like mine did! Both Intel and AMD CPUs are on this list, but in particular AMD Zen2 CPUs (Ryzen 3xxx) out of the box tend to be a bit too aggressive with Boost frequencies and voltages. Several have us have simply turned off Boost in the BIOS, or at least dialed it back a little bit.

Here's the list of all the computers that have had errors during the challenge. Note that all of these tasks completed successfully, but that's only because LLR2 corrects the errors. If we were still running the original LLR, all of these tasks would be invalid.

Task took 56,773.59 seconds :) I see its waiting for validation but was wondering is there somewhere I can see if computer reckons its a prime or not or do you have to just wait ?


You have to wait. We can see the results, but you can't.

Rest assured that those are so rare (none are known to exist) that if it was prime, we'd know, and we'd be getting in touch with you as soon as we verified that it's really prime.

Posted 5 days ago by Profile Michael GoetzProject donor
Just learning... what is a P number. (i.e. what does 95P mean)


P == Peta, or 10^15. So 95P = 95,000,000,000,000,000

Sieving works by using "small" primes to divide the big numbers and easily and rapidly remove any that are composite. When we say we've "sieved to 95P", we mean we've removed all candidates that are divisible by any prime numbers smaller than 95,000,000,000,000,000.

Any way to sort tasks so that those tasks with warnings come to the top? Kinda hard to find them with many thousands of completed tasks listed, 20 at a time.


I know it could be better and there probably will be some more improvements in the future.

My experience has been that if there's one error, there's probably a lot, so if you don't see any errors in the first pages of completed tasks for a single host, you probably won't see any.
