I don't see a day here where there was under 200 exponents factored to 72: [URL="http://gpu.mersenne.info/reports/overall/graph/"]http://gpu.mersenne.info/reports/overall/graph/[/URL]

P-1 is once more limiting than TF. There are 250 factors waiting now for P-1 that have been factored to 72. Plus challsall says we are releasing some back to PrimeNet.

Do you? Not only this incident, but there was the other case where you tried to poach from a completely different project!! And you admitted you knew about it! [URL="http://mersenneforum.org/showpost.php?p=279785&postcount=121"]http://mersenneforum.org/showpost.php?p=279785&postcount=121[/URL]

If you had found a factor the amount of wasted processor time would have been absolutely mammoth from NFS@home.

There are tons of numbers out there that have not been assigned to people to do whatever worktype you want to do. Don't be selfish. Think about the people who are working on the exponent. I would be pissed if I turned in a P-1 and was not given credit because someone else already found that factor with TF. Or if I was working on it and someone told me they had already done it.

My humble apologies.

In truth, I was just being lazy. Not a defence, obviously! I said above (way above now) "I don't usually poach": actually I'm quite sure this was my first time, and it didn't feel good. Quite apart from any issue of credit (and at least with primenet v5, if you have the AID, you get the credit, even if someone else submitted first) it meant your machine spent time on this exponent that it could have used to actually further the project.

I don't think anyone doing P-1 or TF below 20M are in it for the PrimeNet credits. PrimeNet doesn't (or didn't) handle TF reservation below preset limits, soo people extending those limits are out of the loop...

I won't do back-flips when I try extending limits and the TF take all of 5-6 minutes. If I do 500 such test in a week. Trying to find if any of the exponents are reserved for something else like P-1 or DC, is a ridiculous notion. I do the TF regardless of DC status (proven or not) or P-1 limits anyway.

I do however look for TF activity in the range I work, so that I can avoid clash with other TFers. obviously I was alone in those [URL="http://www.mersenne.info/trial_factored_tabular_delta_30/3/10000000/"]range[/URL]

LaurV, with reference to your lengthy post #956, could I just offer you the following tip?

Because different people will have different ideas about what constitutes poaching (indeed you acknowledge that you and cheesehead have different ideas from each other in that post), it might not be a good idea to justify behaviour which impinges on other people's work on the basis of your own particular ideas.

Sigh... It's a bit like debating with a mental midget... :sad:

Let's look at the empirical evidence, rather than emotional hysteria.

As you can clearly see from [URL="http://www.mersenne.info/exponent_status_tabular_delta_7/1/0/"]this chart[/URL], in the last week a total of 1217 LL tests were completed in the 40M to 60M range. Or, 174 a day.

During the same temporal period, as KyleAskine pointed out from another report, not a single day in the last week have we completed less than 200 TF jobs to at least 72 bits. (And note that Xyzzy hasn't reported in in a few days; when he does he's going to blow our charts and heuristics out of the water! :smile:)

Ergo, at this point in time all new LL assignments from PrimeNet will have been TFed to at least 72 bits. And many, additionally, will have been P1ed "well" (we have garnered an impressive amount of P-1 "fire power").

Also, just for completeness, it should be pointed out that the lower candidates take less time to LL. It doesn't matter that they've been "recycled"; the fact is they have not been LLed.

I must be missing something.

I am one of those people that occasionally does TF in the low ranges knowing I V-E-R-Y likely will NOT find a factor (though I have found several in the 3M range it was a small percentage). I have other reasons of personal interest.

However, from my perspective I do NOT find it difficult to ensure any assignment I take is NOT already assigned. I don't do 500 a week; closer to 100.

I start with a query like this (ensuring I exclude currently assigned exponents):
[url]http://www.mersenne.org/report_factoring_effort/?exp_lo=400000&exp_hi=499999&bits_lo=0&bits_hi=60&txt=1&exassigned=1&B1=Get+Data[/url]

Then copy and paste the exponents I want into worktodo.add(or txt) and with basic editing massage them into Factor= statements.

I still do it manually because it doesn't take me more than a minute or two but I know it would also be quite easy to automate the entire process (others have).
