Default UPDATED: The current pre-sieved 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:

3015M-3100M

Old incomplete ranges:

1005M-1010M 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.

900M-920M Zhou_Tong
930M-931M prime_Elsbethen

Code:

You may reserve a range of any size under 50M.

Please reserve the lowest range available. Thanks!

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 ?

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

I began to upload the pre-sieved files here:

http://www.twinprimesearch.org/n333333/0-1000.tps (0M-1000M)

For the moment they will be all 1G .
Tonight (GMT) I'll begin to create the pre-sieved 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 pre-sieved number, instead to do it manually ?

(For reason of maximum space available, there can be MAX (about) 25 pre-sieved 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)

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.

OK so please send me a link to the pre-sieved 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 pre-sieved 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 pre-sieved 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 pre-sieved files. Personally, I suggests:

pre_0-1000.tps (from 0 to 1000M )
pre_1000-2000.tps (from 1000M to 2000M)

and so on, replacing the old conventions.

I think that LLR re-start 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 ?)

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 :)
