From "readme.txt":

M1992031 is not prime. Res64: 6549369F4962ADE0. WV1: B253EF24,1414032,00000000
This means 2^1992031-1 is not prime - a Lucas-Lehmer test says so.
The last 64 bits of the...

Instead of looking at "days to go", you can look at the "exp" column. Exponents expire and are released by the server at 0600 UTC the first time an exponent has a negative value in the "exp" column...

Re: Re: Exponents that haven't had a P-1 test done

This was just my initial guess about the motives of the person running the TempleU-CAS account. He also might not be running P-1 because he fears the high memory usage would interfere with the...

Re: Exponents that haven't had a P-1 test done

I figured this out. I think it is because of TempleU-CAS (combined with TempleU-DI in George's files). Earlier this year, TempleU-CAS ramped up his production by putting Prime95 on lots of P4s in...

The reason that so many exponents have not had P-1 done in the 10M range is that GIMPS was doing first-time tests in that range around the time the first P-1 version of Prime95 was released. A...

I understand the algorithm you are using and I agree that is fairly accurate, but I'm not convinced it is accurate enough to say that the error rate is not still increasing with exponent size. I'd...

I don't believe the server automatically handles any aspect of the double-checking process. Every once in a while, George manually re-releases the exponents that had too many errors. I do not know...

GP2 was implying that the three factors in question might be bogus. I was simply pointing out that he had not done enough testing to be sure of that.

Well, if a factor could be 45 digits and the report is only showing 31 or 32, I would think GP2 would need to try up to 14 digits in either direction. Also, if the factor is a product of prime...

Re: Error rate for LL tests

I don't think we can assume the error rate is not increasing based on the data. We should only consider ranges where all exponents have been double-checked. For ranges where this is not the case (7M...

Re: Cleared exponents that never made it into data files

Very large factors are truncated in the Primenet reports which is why the 102 and 103 bit factors appear bogus. The actual factors found are actually larger than 102 and 103 bits, and the correct...
