Eh... I am not aware that I should do my own verifications... should I do it?

Sorry...somehow I missed this.

Yes you should do your own verifications. Probable primes are not proven primes. Why else would I have asked you if you had proven it?

Based on your output, you appear to have used LLR for testing, which only does probable prime tests (i.e. it outputs PRP's).

Please plug your PRP's into PFGW using the the -tp switch to prove them and post the output here.

Also, please attach your results file(s) or Email them to me at: gbarnes017 at gmail dot com.

All that you have posted here are the PRP's and the original sieve file, which doesn't help.

So far, there have been 3 problems with your range: (1) An incorrect PRP (now corrected). (2) No primality proofs. (3) No results files. If you can prove those PRP's and provide the results, that will correct all of the problems and I'll post your range complete. Otherwise, I'm afraid I'll have to put it back up for reservation and have someone else rerun the range.

Thank you,
Gary

Jason reported the completion of his n=77K-78K range a couple of weeks ago and sent me the results.

The lresults file.
The verification is in progress....

Ian,

I just thought about this: Would you be interested in finishing this drive up to n=100K instead of the Sierp base 3 mini drive II? This one would technically be higher priority since it is for k<100M whereas the Sierp one is for k=100M-200M. It would also be smaller; n=85K-100K vs. n=60K-100K.

If so, I'll send you the remaining n=85K-100K file after you're done with n=78K-85K.

I'll do both. I just finished the 175M-200M n=50K-60K run. Once you clean it up I'll take it. I have resources freeing up to handle both. I'm estimating 16 weeks to do just this part.

I have about 3 days left on 78K-85K on this drive. Each n=1k is taking me about 2 days so that's about a months worth of work on the n=15K left.

So that's 5 months work MINUS any time savings from PFGW PRP finds. Not too bad.

gd_barnes · 2009-09-03, 04:44

You got it. Both of them will be coming your way later tonight. You'll just need to remove the n=78K-85K primes from the Riesel file.

Something tells me you won't take 4-5 months to finish both of them though.
