The good ones, anyway.

34,000,000 - 35,000,000 69bit
 

Could you bring in the exponents in the 34M-35M DC range, those that are TFed to 69bits so I can take them to at least 70bit (maybe even 71bit if we have the time). I can't request them on GPU72 and they don't show up as assigned on the factoring effort report.

[url]http://www.mersenne.org/report_factoring_effort/default.php?exp_lo=34000000&exp_hi=35000000&bits_lo=69&bits_hi=69&exassigned=1&B1=Get+Data[/url]

All exponents in the range which are not yet DC appear in [URL="http://www.gpu72.com/reports/current_level/"]this list[/URL] (second table), and they ARE reserved by GPU72 (or "own" as some say) already. You can take them from GPU72 by manual reservation (the automatic will give you expos in 36M, which help gimps more right now). Other expos in your link which are not "proper" TF-ed, they already are double-checked, and please be aware that TF-ing them to 70 or 71 do not help GIMPS at all. [edit: of course, everybody is free to do what work type he likes, I am still strongly adhering to this thinking!]
[edit2: the factoring effort reports don't usually show if the expo is reserved or not. The "[URL="http://www.mersenne.org/report_exponent/default.php?exp_lo=34000000&exp_hi=34500000&full=1"]expo status[/URL]" reports, usually do show that]

My mistake, I didn't realize they were already DCed. I should have checked their status (LL/DC) before posting.

They aren't already DC'ed -- LaurV misspoke... :razz: :wink:

I actually "threw those back" to Primenet a couple of days ago. The reason was that the 34M range is at the "tail end" of the DC "Category 3" range -- we have so much of a buffer for Cat 1, 2 and 3 that these won't be assigned by Primenet for another six months to a year from now. As in, working on them is not currently a high priority.

On the other hand, we were falling behind with appropriate TF'ing for the Category 4 range. I actually had to bring some of our LLTF'ing firepower (Jerry, LaurV and myself) down there for a couple of days to build up some candidates -- and we really can't spare the LLTF'ing firepower at the moment.

However, I have brought the 34M range back into GPU72 for those who really want to work that range. Please know that the "What Makes Sense" and "Lowest TF level" options default to 35M or higher. "Lowest Exponent" will honor the request (read: 34M candidates, as long as they are available).

Based on the above, while you are (of course) free to do whatever work tickles your fancy, it would be appreciated, and of greater short-term benefit to GIMPS, if you did at least half your TF'ing work at 35M or above.

Whoops! :redface:
Sorry, I didn't know the details, but the posted lists (I mean both, mine included) contained a lot of already-DC-ed exponents too.
Sorry for this confusion, and for any harm I caused :smile:

Regarding this discussion, is Cat4 DCTF or Cat4 LLTF a bigger concern at the moment? I would have to imagine the LLTF is where the biggest strain is, unless we've built up enough of a buffer for the churners.

Thanks for the clarification. I'll try to split my humble power between 34M and 35M, not that my 300 GHzdays/day is going to make a huge impact.

Cat 4 LLTF is the biggest issue at the moment.

Surfing the edge of the wave, baby! Just the way we like it! :wink:

Every cycle is valued. And you might be surprised by how important only 300 GHd/d is to feed the DC Cat 4.

I've got about 600 myself and I'm in the top-20 yearly GIMPS contributors for TF, so 300 itself is quite substantial. Every bit helps, but don't be surprised by your impact over time.
