No Results Posted

Hi there,

New member. Been running Prime95 on a MacPro for a month or so now. Going fine, and seems to be happy communicating results to the server, but there are no results listed for my account on mersenne.org.

Any thoughts?

Thanks.

Can you communicate your user name to Madpoo or George, or just post here an exponent that you worked on, or finished some LL or DC, or you have it just assigned, so we can investigate?

The main and primary work done by the project is performing LL tests on numbers like 2^p-1 (where p is a prime itself). The project has been operating long enough that each individual test of a specific 2^p-1 takes a *long* time, up to a month or more depending on the processor. For reference, my four year old Sandy Bridge desktop processor at 3.4 GHz can do one "iteration" of 2^(35,019,883) - 1 in approximately 20 milliseconds, and it needs to 35,019,883 such iterations (approximately), resulting in one test taking a bit more than a week.

That is a number which has already been tested once, and for which I'm doing the double check to verify results; numbers which haven't been tested before are on the order or 2^(70,000,000)-1 or so (for prime p, obviously 70 million isn't prime); each of those iterations takes closer to 50 milliseconds, and at 70 million iterations, is more than a month for one test.

So yes, this is exactly what you should expect. If you log in to http://mersenne.org, you can then go to http://www.mersenne.org/workload/ to see your current assignment. It should tell you what exponent you are testing, and the estimated completion. You can post what it says here if you're unsure how to interpret it.

Thanks all.Will follow up with madpoo, as suggested.

You could look in the prime.log file to see the communications log between the client and the server. Maybe the client fails to communicate with the server?

Thanks again.

My userid may not have been spec'ed in Prime95, so my prior results are perhaps detached from me. It seems that my current assignments are now visible at mersenne.oeg. That wasn't the case before, so I'm thinking I may have solved the issue.

Appreciate all the replies.

Oh good, because I haven't had a chance to look.

Anyway, I see you have 8 assignments and they all checked in earlier today so looks like you're good to go.

Thanks. I did find my prime.log and results.txt file (attached here), which do have results reported that seem to not be credited. If it's worthwhile to to get those results into the system, fine, otherwise, I'll just carry on.

Thanks again.

It looks like your results were reported as "ANONYMOUS". I believe these files should allow George or MadPoo to transfer the credit for them to you.

I should mention that the log file contains active assignment IDs that you should not publicly reveal. Perhaps a moderator can alter that attached file to mask the IDs?

Thanks again to all for your help and suggestions.

The results file is right, the assignment keys can be easily checked by the server gods, so the credit should be transferred to you.

For the future don't post assignment keys for work you didn't yet finish (lines 282-333 in prime.log should be deleted or masked), some bad guy can use them to steal an assignment from you (in fact, some supermod can delete the prime.log attachment, it is not useful for this discussion, all info for credit transfer is already in results.txt).
