 2015-06-19, 16:48 #1 eltodesukane   Jun 2015 102 Posts Countdown units - on the GIMPS Milestones Report? What are the units in the GIMPS Milestones Report countdowns? http://www.mersenne.org/report_milestones/ Countdown to testing all exponents below M(57885161) once: 189 189 what? How long will that takes? Thanks

You are correct. It could be phrased:
Number of exponents that need testing completed below M(57885161) once: 189

 2015-06-20, 00:07 #4 eltodesukane   Jun 2015 2 Posts Thank you. That make sense. I did not realize testing a single exponent is so much work. Countdown to first time checking all exponents below 57M: 2 (Estimated completion : 2015-08-02)

That is based upon the computers that those exponents are assigned to. We still have some old computers with some old assignments. They are still making slow progress. They are being watched. If they fail to meet minimum standards, the exponents can be reassigned.

I don't know but this kind of thinking is part of my reasoning for prioritizing the double- or triple- checking of suspect results (and perhaps the results of known unreliable sources).
