I agree with what Uncwilly says, on "Do what you like best". There are valid reasons why someone would want to test a 100M(332M) exponent.

We have been working of late on moving some of these forward. Current plans are to see all of the first 100 to 78, then moving that CPU to a different set of assignments.

So um... How should I go about getting exponents that have been factored enough to begin LL immediately? Or what should I be doing?

You click [URL="http://www.mersenne.org/report_factoring_effort/?exp_lo=332192809&exp_hi=333000000&bits_lo=75&bits_hi=99&exassigned=1"]here[/URL]. Remark the selection of checkbox and the bitlevels. The list is (usually) pretty short. You can play around (like changing the upper limit, bitlevels, or unchecking the "reserved" box to see the difference). As the LL in this range takes months, you can do this manually from time to time. The best/fast way is still to select any expo you like [i.e. not in the list] and ask on the forum for somebody to factor it. Don't be shy, we are here to help :razz:

Now, endless discussion can be done about the fact that the most of the reserved exponents will never be finished, most "beginners" come and reserve an exponent because they read something in a news paper or web page, and they expect to find a 100M decimal digits prime by tomorrow and go home with $50k from the EFF's money. When they see how long it takes, they just give up, without unreserving, and never return. As the exponents in this range are not (so often) recycled, the reservations persist for a long time.

So, if you really want an expo which is reserved, because you dreamed last night that it may be prime, just say so. Someone will check if the reservation shows any progress, and most probably you can have it, if you are really willing to invest that HUGE computing power you have, into it.

@Madpoo, as we see you like to play with that database :razz:, maybe this is a nice homework, to make a list of 100M dec digits exponents which are reserved for LL by the people who never did (or did too less) LL work in lower ranges.

Some of the exponents that have a good amount of TF may still need P-1.

This ([URL="http://www.mersenne.org/report_factoring_effort/?exp_lo=332192831&exp_hi=332999999&bits_lo=79&bits_hi=99&exassigned=1&tftobits=72"]link[/URL]) will produce a list of available exponents that meet a reasonable level of TF and are available. The ideal bit level is 81 if there is a GPU to do the work, else it is 78.

If you have a bunch of memory available, check with [URL="http://www.mersenne.ca/prob.php?exponent=332192831&prob=5&work=&factorbits=79&force_b1E=&force_b1=&submitbutton=Calculate"]this tool of James's[/URL] to make sure that the exponent has had enough P-1 for about 4-5% probability of finding a factor, before you take the number for LL.

Would it be possible to unreserve ~60 abandoned exponents shortly before I get those ~30 blades I'm expecting in?

[QUOTE=aurashift;401238](...) those ~30 blades I'm expecting in?[/QUOTE]

:shock::shock:

May I at least try to lure you into giving a hand to this small sub-project (GMP-ECM on very small numbers, namely the (in)famous M1277)? The idea of using all that memory is most enticing... :smile:
