 2021-06-17, 18:02 #556 drkirkby   "David Kirkby" Jan 2021 Althorne, Essex, UK 1101010002 Posts I got a DC assignment for M102164971, but are actually doing a PRP test as requested above. Code: PRP=AID,1,2,102164971,-1,77,1 [Worker #1 Jun 17 17:57] Optimal bounds are B1=391000, B2=18346000 [Worker #1 Jun 17 18:11] Available memory is 376728MB.

Which happens automatically... You would know this if you read more...

The certification is taken care of. But why did you repeat the P-1 with lower bounds for both B1 and B2. This doesn't make any sense. It cannot find any new factor.

There is no need to add the M in front of the number when using the [M] tags. Your post was not to: requests for DC and TC's and claim of exponents. as in post #1 There is no cause to post this as noted below.

Because of the last sentence of the next quote.

Not only does it happen automatically, the PrimeNet server must be involved between the person that does the PRP and the one that runs the cert. But, to know that requires reading. Also, there is no manual assignment type for certs.

 2021-06-19, 18:09 #561 drkirkby   "David Kirkby" Jan 2021 Althorne, Essex, UK 1101010002 Posts I may have put this in the wrong thread by mistake. (Yes, I am human, and I do make mistakes). There was a thread by Uncwilly requesting double-checks of some dubious exponents. Despite I would rather have done a first time PRP test, I decided to help out and check one of the exponents on the suspect list. I did comment that I had started the P-1 by mistake. I realised my error, but decided to let P-1 complete, as I was keen to know how much RAM would be used on stage 2. It was only 190 GB or so, which was far less than the 340 GB or so for a similar sized exponent a couple of weeks ago. I think the other one had erroneously be issued by the server indicting it would safe 2 primality tests, so probably B1 and B2 were larger, requiring more RAM. I was keen to experiment, so let it run. Personally I think the Mersenne numbers look better with the M, so I prefer M102164971 to 102164971, So that was a conscious decision. My comment about the certificate was just to highlight the fact that the prime/composite nature of the Mersenne number had not been fully settled at that point. I do know the server issues the certificates, so the comment about reading more was not called for. Whilst one can't get a manual assignment of verifying the proof, I suspect if one was determined to do so, one could probably get an assignment for a specific exponent n by putting the following in local.txt Code: GetMinExponent=n GetMaxExponent=n
