R548 to n=400K
R549 to n=400K

DAMN, I was talking about R523, not R532. My mistake. :/

R523 is @7T. 15,5K n-values left, sieving goal is 20T.

Dear other sievers,

I decided to to some pre-sieves with srsieve. I´ll focus on Sierpinski for the first months.
I´ll sieve to p=50B, the output file will be uploaded to dropbox (I´ve tested GitHub, but you cant download an selected file...)
I´ll post the links to the files to the forum. Or give me your Mail, that I can give you access to the files, without posting links.

Progress:

Code:

S798 with k-value 33 (N=200K to 1M) sieved to P=50B
S836 (k=2)(n=200K to1M) sieved to 10B (maybe I´ll go to 50B in a few days.)
S17 (k=244; n=2M to 5M) Running to P=50B (This can take a while...)

S798
S836

@lalera Tell me which bases you will run, I can pre-sieve some files for you. :)
@gd_barnes Don´t worry, I´ll write very often here in the future. Sofar I saw "only" two persons are sieving. We should get this under control.

hi,
i do plan to do some bases in the R7xx range in the year 2017
... just take the free ranges ...

gd_barnes · 2016-11-12, 07:22

MisterBitcoin,

See the PM that I sent you. If you are sieving any range for n>100K, please consider a sieve depth of at least P=5T (5000G) in order for us to show your reservation in the first post here and for me to post the files on the project reservation pages.

Note that for the bases you are talking about, the optimum sieve depth will be far greater than P=5T but that is a good minimum point to get the sieving of the files started.

I started the the following bases (only 1 k left)

Code:

R702
R727
R730
R731
R736

All sieved to P=50G, now running them to 5T.
I sieved to n=500K in the hope the prime will be found

I tested R709 (9k´s left), but I got an error with sr2sieve. [ERROR Line 1: Malformed line in input file]
Line 1:

Code:

ABCD 170*709^$a-1 [100002] // Sieved to 419078549 with srsieve

LaurV · 2016-11-12, 15:41

If you have a single k then you should not use sr2sieve, that is for many k's and it is slower. Someone correct me if I am wrong here, but I think sr1sieve is the fastest here. Even for 2,3, k's you can do separate sr1sieve runs in the same time

That is the correct header for an sr2sieve file. I do not know why you got the error. The following command should be issued at the DOS command prompt:

sr2sieve -P 5e12 -i sieve-R709-100K-500K.txt

Just replace the file name with whatever your file is.

Is that the command that you gave sr2sieve?

His example is sieving R709 with 9 k's remaining. Sr2sieve is correct to use.

MisterBitcoin,

You are attempting to reserve too many bases at once and just kind of going all over the place, which makes it difficult to administer. With all of this I cannot tell what it is that you are doing.

It looks like you are trying to sieve 11 bases at once. For now, please reduce your reservations to 3-4 bases. After you are done, you can reserve some more. We do not need to know how far you have sieved so far. Just let us know how far you plan on sieving each base.

For people new to the project, it is important that they know how long any effort is going to take because most people well underestimate the personal and CPU effort involved. Please give us a time frame on how long you think it will take for you to sieve the 3-4 bases to at least P=5T.

Thanks,
Gary

Sieving R958 from n=200k to 500k.

Will do a PRP test at n=400,000 to see roughly what amount of sieving is reasonable. The initial srsieve sweep to 1e10 has left <4000 candidates or so.

MisterBitcoin · 2016-11-14, 19:26

Sorry that I could reply earlier. I was really busy to setup my new dedicated server (Debian Jessie). I´ve got some problems setting up the gnome environment...what ever, it was an short night. ;)

After 5 hrs sleep and 8 hrs work I tryed to start sieving on 7 threads. And, surprise! Nothing works, again.
I tested everything...(I tryed to start sr1sieve via bash, (allready maked the file executable via the filemanager) but just got "commando "file-name" not found". [I hoped setting up is as easy as it is on windows...] (EDIT: Solved, I was in the wrong folder...:/)
I searched in atleast 4 forums for an sollution, well no sucess...sofar. If someone could help me or got an idea how to solve it, please pm me. (German would be easier...last linux use is 1,5 years ago, notice I´m just an user not an admin...additional I god headache. I love Mondays...^^)

EDIT: I got an: Syntax error "(" unexpected. After I maked the sr2sieve with "chmod +x" executable I tryed the following command:

Code:

sh sr2sieve_x86_linux -i input.abcd -pmax 5e12

If I try "./" or "bash" I´ll get some other errors. Like "file not found" or "file not executable. (I´m in the right directory, now). I´m out of motivation...allways I have these problems...Never give up, live is to short to let an Error win.

@gd_barnes Well, I hoped sieving is much faster then it is. Well, I should get another dedicated server in 3 days, with 12 more threads (CPU´s). It will be used to finish R602 and sieving my reserved work. ETA´s are coming when server is running. The first 4 tasks had an ETA on my main computer, estimate an 4 day ETA.
