This is the reservation thread for the Twin Prime Search sieving. The sieve is for k<100G for n=333333.

Before reserving a range, please visit the Welcome thread for instructions and to download the setup files. If using NewPGen (32 bit OS's), see instructions here: NewPGen Instructions. Be sure to make reservations in this thread instead. If using tpsieve (64 bit OS's), continue below. NOTE: tpsieve uses up to 800MB RAM. If this is an issue, then it's better to utilize NewPGen.

NOTE: Manual BOINC cobblestones are available for this sieve. Also, this sieve is best suited for 64 bit OS machines.

tpsieve_7300TE1 is the current sieve file and can be found here: Sieve file.
tpsieve 0.2.1 is the current version we are using and can be downloaded here: tpsieve Sieve Software
32 bit OS's should use NewPGen.
The factor upload folder is located here: Factor Upload

To reserve a range, simply post in this thread the range you wish to reserve, using the following format for your message: Reserving Range Username. For example: Reserving 0T-25T Lennart

k<100G for n=333333
0000T-8500T TPS Sieve at Mersenne
8500T-25000T TPS Sieve Archive at PrimeGrid

25000T: Final Goal

Sieving CLOSED at 25000T

Review other reservation posts before selecting a range. Also, check to make sure you have the latest sieve file.

Updating sieve file
Download and unzip the new sieve file. Stop tpsieve. Edit tpsieve.bat (tpsieve.sh for Linux) file to new sieve file name. Restart tpsieve.

Multicore systems
Please visit the Welcome thread for special instructions on how to easily utilize all cores. NOTE: do not use more than -t2. If using a quad, create two folders of programs and files, split the range, and run two instances of -t2.

Process Priority Switch
Default is not to change process priority. However, if you are affected by the usual Ubuntu Linux problem of CPU frequency scaling, fix this by adding --priority=normal.

-z --priority=N Set process priority to nice N or {idle,low,normal}

Timings at 20P show that sieving is still favorable; therefore, the available range has been opened to 25P. Thanks for all the help!

The sieve is finished!
Let's hope the llr can restart soon

I wonder how long it would have taken to get this goal completed if PrimeGrid would not have taken the time to implement it here....

1. Factor file from:
8660T-8680T John COMPLETE
is missing.

2. In factor file from:
23200T-25000T Puzzle-Peter COMPLETE
range 23600T-23650T is missing.

I'll have a look at this tomorrow. Sorry!

Very curious where we are with TPS. Are we ready for LLR'ing or do we need more sieving? I know a whole lot of people wish to get that badge and well I personally loved just doing TPS for the sake of how well it worked on my computers. Just thought it's been a while and wanted to know what the status is :) Thanks

I thought TPS was done and dusted?

TPS for n=333333 is finished as a twin has been found. There are still a lot of nicely sieved candidates though and a small probability of finding another twin among them. Maybe I could do some LLR work offline *lol*

Anyway, sieving for a whole range of higher n values has started...

If we could add it to PRPNET then I'm sure more people would be able to help out. Or if I have it mixed up at least add it to the Sieving thread like Primorial sieving and such, so people could reserve chunks like they do with the other sieving efforts here on Primegrid.

A sieving effort for 1<k<10M, 480k<n<500k was started in August, but MooooMoo disappeared a while ago and I don't think that anyone is still sieving... so the project can be consired inactive if not dead.
