UPDATED: The current presieved range reservation thread and stats page
Reservations have been temporarily stopped. Please see pacionet's note at the bottom of this thread.
Post in this thread to reserve a range for LLR'ing. Report results the same way. The output file only contains twin primes, so check your lresults.txt file for single primes. Lowest available ranges: 3015M3100M Old incomplete ranges: 1005M1010M Dailian Really old ranges: These ranges were reserved more than a month ago. Please give us an update of your progress, because we haven't heard from you since then. 900M920M Zhou_Tong 930M931M prime_Elsbethen Code:

Reservation for n=195,000 are temporarily stopped.
You cannot reserve other ranges for the moment. Also PrimeGrid has stopped the reservation. We plan to test our next exponent soon.

MooMooo, do you think that will be possible to start LLR testing of n=333,333 soon or not ?
What are we waiting for ? Last fiddled with by pacionet on 20070116 at 16:09

LLR testing will be available as soon as Rytis is ready to put the presieved files onto PrimeGrid. I think this will happen sometime around this weekend, when his exams are over.

I began to upload the presieved files here:
http://www.twinprimesearch.org/n333333/01000.tps (0M1000M) For the moment they will be all 1G . Tonight (GMT) I'll begin to create the presieved page. If you have updated versions of the files please send me a link to the file (please create files with the same ranges of those present on the site). Somebody can send me some script/program (Windows) to create single 1G range files from the entire file of presieved number, instead to do it manually ? (For reason of maximum space available, there can be MAX (about) 25 presieved file at the same moment on the server, but this is not a problem) Rytis, when he will need new ranges, can access here and download them (in this way we 'll always have an updated version in a single location) Last fiddled with by pacionet on 20070117 at 13:15

pacionet, we haven't deleted factored numbers yet.
We need to decide when we will start LLR, and I will merge everything the day before. And some technical details: I suggest the files to be of 5G. And, probably zip them. Anyway, we first need to remove factored numbers. Last fiddled with by gribozavr on 20070117 at 17:40

OK so please send me a link to the presieved file, when it is ready.
Putting them on the site, in my opinion, should simplify Rytis 's life: he can create an automatic script to dowload them when necessary (when the queue of PrimeGrid is almost empty); otherwise he should ask on the forum "Give me next presieved file",then we must use a temporary URL to upload it, and so on. I have this process in mind: 1) Different users sieve n=333,333 and send their file to somebody (gribozavr ?) 2) somebody (gribozavr ?) merge and work on them to create updated presieved files 3) gribozavr upload them on the site (or send them to me and I'll upload them) 4) the automatic script download updated files when necessary Do you agree ? As suggested by jimblazek we must use an unique convention for the names of presieved files. Personally, I suggests: pre_01000.tps (from 0 to 1000M ) pre_10002000.tps (from 1000M to 2000M) and so on, replacing the old conventions. Last fiddled with by pacionet on 20070117 at 21:04

I think that LLR restart 22 or 23 January. No problem to upload 5G file (zipped or not). Rytis, do you think it is the right size for PrimeGrid ? (that is, all the users join us ?) Last fiddled with by pacionet on 20070117 at 21:42

I already have the automated download and import script, it just needs to be adapted to 333333. Yes, 5G should be fine.
I plan to restart on 23rd, so until then sieve like there is no tomorrow :)
