starting again with 332216147 - 332217971, most are to 68 already, going to take the range to 72 first, then 72 - 74. the first few are assigned to LL testers already so should I bother with those at all?

Of course in the 100 000 000 digit primes range some of the assignees will skip trialfactoring in the misunderstanding that they will go quicker. I still think it is better to just wait until they drop out.

You are not sure and thus may be poaching. There is no urgency to treat those numbers. Even if it might be fun to search for the work ;-)

[quote=Uncwilly;151423]If they show no progress after the number has been assigned to them for 15-30, I think that it is likely that they have skipped the TF.[/quote]I'll echo Jacob (though more softly and verbosely).

When one tries to deduce what is going on in an assignee's system, one runs the risk of having one's invalid assumptions about what is and is not shown in the reports lead one to a false conclusion.

That was doubly true in my own case.

Several years ago, the nonstandard way in which I was processing my LL assignments may have made it appear to someone looking at PrimeNet reports that I would be "holding up" some milestones, but in fact I was careful not to do that.

Then, the way in which someone else reported LL results to PrimeNet for exponents that had been assigned to me made it appear to me that the person was deliberately poaching my assignments. However, after I recently established communication with that person, he emphatically assured me that he did nothing of the sort, and had tested only exponents that had been properly assigned to him. That made me realize that I had not previously considered the possibility that all the evidence I had could be explained by some flaw in the assignment system rather than by poaching.

So, please don't do anything on exponents that are assigned to someone else. There are an infinity of Mersenne numbers with prime exponents, enough for everyone to work on exclusively with plenty left over.

I have taken the advice of others to heart. I now grab the factor level report, make the worktodo.add, let Prime95 register assignments, then cull the N/A's.

Here is a progress status report for the range from 332192831 to 332259937

[QUOTE=S485122;154726]This shows that 21 assignments are overlapping (Unproven -Assigned-Available)[/QUOTE]I think that there are some expos that the server shows as assigned to me to LL, that are actually left over TF's. I want to get my hands on the machine and look at the worktodo.txt. I want to make sure that the entries are right, or fix them, or.... I haven't figured out how it happened. They may be part of the 21.

That and maybe the ones that got assigned LL, but TF killed, as reported previously.

Hey UncWilly, I'll join in when I'm done with my poking around below your range (321M 6-9 range).

Some of my cores have been sidelined from this due to lack of access. They are still working for GIMPS. I have put one new core to working the range above this. It is a slower one and I will keep it at the lower bit depths. Once I get all the exponents in this range to 2^68, I will put that core onto the next higher area, bringing those expos up to 67 then 68. I plan on reviving the other cores and have then work the 69-72 area for this range.

[QUOTE=Uncwilly;159660]Here is a progress status report for the range from 332192831 to 332259937[/QUOTE] I am now extending this particular range up to 332319979. The next stats (2/20) will reflect that. Anyone wanting to help can either work above me or take some of the higher bit levels.
