Default Why does my work not appear in CPUs, but does on Assignments?

I'm doing PRP testing of a large exponent

https://www.mersenne.org/report_expo...2646233&full=1

This shows up on my Exponent Status as 2.2% done, and updated 2021-02-21 (i.e. today). I just done a manual upload of latest expected completion data. My prime.log file shows an estimated completion of 25th May.

However, this is not seen in my CPUs. There's nothing to indicate computer "jackdaw" is working on this - see screen shots attached. I can't understand why one part of the Primenet server is showing the information, and another is not.

My prime.log file shows the data is being uploaded to the server. I've not dropped the CPU at any time.

If you look at the list again, for example now, you should see it there again. It was not showing, because the CPU was doing some other task at the moment - PRP certification. These are randomly assigned to users who opt-in (or more specifically do not opt-out) for doing the certification and are prioritized. As it was a 10M exponent cofactor result, it took a very short amount of time.

Try going to: https://www.mersenne.org/workload/
Do you see the exponent in question there?

Yes, it shows at



- see attached.



It still does not show at https://www.mersenne.org/cpus/ but what I notice is that https://www.mersenne.org/cpus/ shows a certificate of 10309619 having used over 400 GHz days, and 0% completed. That seems a bit unlikely.

That is the total output of the CPU, not for that assignment.

I edited your attachment to hid your assignment ID's,

As I wrote before, I do see it there, but it does not seem to be updating. It still says 0.9% done, estimated 94 days to go, finishing on 2021-05-27. Yet the output of mprime shows something quite different.

There's obviously a fairly big difference between 0.9%/94 days and 3.76%/66 days.

So there seems two issues

1) Not updating at https://www.mersenne.org/workload/
2) Not shown at https://www.mersenne.org/cpus/

worktodo.txt had two lines in it - the big PRP test followed by a certificate. I stopped mprime, swapped the order of those, and re-started it. The certificate was quickly shown as completed.

https://www.mersenne.org/report_expo...0309619&full=1

but when mprime finished that, and started back on the more CPU intensive task, it still does not update on the GIMPS website.

I may have "confused" the server, as I did unassign one exponent from mprime, which still showed as assigned to me on the website. I then unassigned it on the website.

I'm obviously not keen to waste 64 days computing something, if it is no use to man nor beast.


If the worst comes to the worst, could this manually be updated later? Or would I just be better to stop the process and start something else? If I do that latter, I think I will take on something less ambitious!.

Okay, things have changed. I decided to start a smaller exponent



https://www.mersenne.org/report_expo...9841707&full=1


which will take about 8 days, so 10% of the time. Now



https://www.mersenne.org/workload/


shows sensible data for the large exponent. Now it is showing it is 3.80% done, which is about right. It also has extended the end data a bit, as I'm working on the smaller exponent. But https://www.mersenne.org/workload/
looks a lot more sensible than it did an hour or two ago.

How often is your machine set to send estimated completion dates to PrimeNet. It should only do so once a day or so. Even less is ok if you are working on numbers up near 332M.

1) Not updating at https://www.mersenne.org/workload/
That is what I addressed in the lines above.

Not really the place to check for your current assignment progress.

That had no actual effect. The Cert assignment is a "priority" assignment. Once mprime notices it in the queue, it starts that and will finish it ahead of other assignments.

If you manually pulled it out of the worktodo file, mprime won't know to tell PrimeNet about it.

Think of it as "cycles". There is a more or less set amount of compute that is needed to test that number. If you don't test that number, someone else will. If it is up in the 332.19M range, then it is a 100M decimal digit number. If it is prime, then it is an award winner.

If you have the save files on your machine still, you could resume it. What you do is your own choice.

I would suggest that you try to ask more of your questions in a single thread. That will help the people that answer you see the full scope of your issues.
