Question as I am working my way through all the projects trying to get a gold badge as my OCD has kicked in.

Of the 31 WUs I have crunched on PSP. 1 Error, 6 Completed, marked as invalid. 9 Completed, validation inconclusive 10 Completed, waiting for validation and 1 Completed and validated 1st. Of all the other projects, none have had this high of a rate of invalid or error WU's, is that something with PSP or me?

Also what does Completed, validation inconclusive mean? I have never seen that result before. How does the Completed, marked as invalid work as well? Given that each WU takes about 2 days 12 hours to complete that is a lot of wasted computing power for the invalid and inconclusive units. Any tips to minimize this going forward?

Thanks!

Your computer is experiencing hardware failures. Usual causes are overclocking, heat, bad memory, a BIOS in need of of updating, or a bad power supply. It could also be a bad CPU, and while that does happen, it's rare to have a faulty CPU that produces bad results but doesn't also crash Windows.

Also what does Completed, validation inconclusive mean? I have never seen that result before. How does the Completed, marked as invalid work as well?


The result of each LLR test is a 16 digit hexadecimal "residue". In order for your result to validate, the residue you return must exactly match the residue returned by your wingman. If they match, both results are validated and receive credit.

If they do not match, they are temporarily set to "Completed, validation inconclusive" and a third task is sent out. Presumably that third task will match one of the two original tasks. If so, the two matching tasks are set to "Valid" and get credit, and the task with the incorrect residue is set to "Invalid" and does not get credit.

If the third task doesn't match either of the original the two tasks, then a fourth task is sent out. This continues until we have two matching tasks.

Given that each WU takes about 2 days 12 hours to complete that is a lot of wasted computing power for the invalid and inconclusive units. Any tips to minimize this going forward?


If you're overclocking, set the clocks to be slower.

Check the temperatures and make sure nothing is overheating.

WARNING: Power down the computer, unplug the power cord, and take proper grounding precautions before making any hardware changes!

Remove the memory, clean the contacts, and re-seat it. If appropriate, try running with just half of the memory, and then with just the other half. If there's a bad memory module, removing it and running with just the good memory should make the problem go away. If you have two memory modules, it's very likely you can remove either one and the system will work fine. If there's more than two, you should consult the motherboard's manual.

Make sure the power supply is sufficiently powerful. If you have a spare, see if replacing the power supply helps.

Thank you for the very fast reply!

Obviously not what I wanted to hear but I will have some diagnosing to do.

I just switched from SDD to a m.2 drive for my primary HDD around the time the issues first popped up. I did a copy and not a clean install. Bad I know. Also overclock but watercooling keeps the temps under 70c. I will check the bios, drivers and turn the clock down some.

Thanks!

If you're overclocking, regardless of the temps, that's the #1 suspect. Start by running at stock clocks to see if the problem goes away. If it does, you know that's the problem. Then you can start playing with the overclocking to see how much you can get out of the CPU. And when you do -- then go and back off a bit from the best settings. You want some headroom so that an unusually warm day won't ruin a long calculation.

LLR is the most brutal program you will ever run on your CPU. You may never see a problem running anything else and still get errors running LLR.

LLR is the most brutal program you will ever run on your CPU.

Let me sign "brutal" with rainbow ink. It can get to a point where a simple reset due to power failures can cause RAM to miss training and suddenly start producing errors.

Noob question: Does rainbow brutal apply to all LLR programs or just PSP LLR?

Because if it is all LLRs then I think that since I have gotten gold on 321, esp,gcw,pps and sob and been running my computer at a slight overclock with stock voltages 24/7 for 3 mo's of LLR was more stressing of the system than I thought. However I also didn't start getting errors till PSP LLR was going.

I was pretty cavalier about the LLR program and running 24/7 in the background while also doing photo editing and other cpu intensive tasks which I should maybe now understand why was getting errors....

Have a I7-6800K @ 4.5mhz with stock voltage that is water cooled. 16gb ram at stock timings.

This applies to all LLR, however PSP has the second longest tasks, and thus has the highest likelihood of having an error occur during the test. SoB is the only one that's longer, and it's likely that if you ran SoB now you would also see errors.

Tasks having worked in the past doesn't mean that they will work today, especially if you're overclocking close to the limit. Over time, electronics degrade, ambient temperature may increase, and cooling systems degrade.

They can be differently brutal. "large FFT" tests will often stress the ram, memory controller as well as the CPU. "smaller FFT" tests will likely sit within the CPU cache and stress the cores more, but not be demanding on the ram.

6800k is Broadwell isn't it? I'd say 4.5 GHz is pretty good going for one of those, and at stock voltage at that. Without looking it up, isn't that also the first CPU that Intel introduced AVX offset on? That is, when doing loads like LLR, it may use a lower clock than otherwise. Is it actually running 4.5 GHz all cores when you run LLR? If it does have AVX offset option, that can be used to lower the clock in these use cases, while remaining at the set full clock for less demanding workloads.

You might find downloading the latest Prime95 and using its stress test mode easier to diagnose problems. Prime95 and LLR share the same core math library, although there are some differences they can be considered the same for testing. If you can run small FFT without error, the core itself is probably ok. Then move on to large FFT which will also stress the ram side more.

Sorry...6700k. Skylake processor.

Got it running at base speeds now and as soon as lightroom gets done processing I will download prime95 and get to stress testing some overclocks.

How much extra wear would you, in your opinion, say that running LLR 24/7 puts on a processor/motherboard? Lets say normal lifespan of 5 years... we talking half that ?

thanks!

I'm not sure anyone has really good information on how crunching affects longevity. But we have lots of experience with what makes computers reliable, meaning able to produce the correct result.

Personally, I don't worry too much about most of the components in a desktop computers, except for a GPU and anything that spins. I've found GPUs usually have the shortest lifetimes, whether you're crunching or not. Hard disks (the spinning kind) can fail, as can fans. Other than that I usually get at least 5 to 10 years out of a desktop, and more often than not it's turned off because it's obsolete, not because it's broken. I had a desktop fail in 2017 -- but it was about 12 years old by then.

Laptops are another story. They're not built for continuous high power loads like this, I and usually only subject them to crunching for short periods of time. I've also become a convert to using TThrottle on laptops to keep the temperature down (at the expense of computing speed.)

You should check to make sure your BIOS is up to date. It probably is, but when Skylakes were new, there were some problems with CPUs that resulted in calculation errors. It was fixable with a BIOS update. That was years ago, and I don't expect any Skylakes today to have that problem, but if you were an early adopter of the Skylake CPU and never updated the BIOS, it's likely the problem wouldn't show up until you started running LLR.

Interesting problem.

There's nothing you can do to fix that task. We may, or may not, be able to correct it on our end. But the more interesting part about this is how it could have happened.

The filename llrPSP_308585931_0_r359405060_0 is wrong. The highlighted portion is what's called the LLR-ID, and that's not the correct LLR-ID for that task. It's the LLR-ID for a task you did a long time ago -- long enough ago that the task has been purged from the database. The real question is why BOINC used the old filename instead of the correct filename.

BOINC uses symbolic links for the output file, and my guess is that the link for that long-ago result got stuck somehow -- perhaps it's write protected, or perhaps something transient prevented it from being deleted when it was supposed to be deleted. Sometimes that can happen when you restore from backups, sometimes it's a side affect of interactions with backup programs or virus scanners, or other background programs.

The important thing right now is to make sure the problem doesn't happen again. I recommend you do the following steps, in this order:

1) Set "No new tasks" on every project.

(As an alternative to (1), you could also abort all the tasks instead of letting them all finish.)

2) Wait until every task on your computer is finished and reported back to the server(s).

3) Using Windows explorer, navigate to the directory C:\ProgramData\BOINC\slots\ . There will be a bunch of sub-directories called 0, 1, 2, 3, etc. Look in each directory. They should all be empty.

4) If they're all empty, you should be good moving forward, and the problem probably was temporary and corrected itself. If there's anything at all in any of those directories, you should delete those files.

That should fix the problem if it still exists. However, the underlying cause -- whatever caused that symbolic link to get stuck in the first place -- might happen again since it's not clear what that underlying cause actually was.
