Riesel base 2 discussion

gd_barnes · 2008-09-23, 00:24

I'm going to shortly remove the link to Rieselsieve from our web pages as the link is no longer valid and hence it appears to no longer be a project.

Can someone refer me to a list of the k-values remaining and the search limits for each one? I will then manually list the info. in the CRUS web pages.

Unless someone knows otherwise, technically the effort is now wide open for anyone to begin anew on so if anyone wants to coordinate any efforts here for Riesel base 2, go right ahead! I'll go ahead and remove the green project reservation from the page.

Thanks,
Gary

I was able to obtain the k's remaining and test limits for the Riesel Sieve k's from www.rieselprime.org. Note that the test limits are several months out of date. For the 4 k's < 32000 that affect our Riesel base 4 and 16 conjectures, the test limits were limits that I got < 2 months before the project went down so they are more up to date.

The Riesel Sieve project going down had a major ripple effect through the CRUS web pages. The Riesel Sieve remaining k's are now incorporated with the CRUS remaining k's for Riesel bases 2, 4, and 16. All links to the Riesel Sieve project have been removed. References are still made to the 'former Riesel Sieve project' about which k's were searched by it on the various powers of 2 bases.

As far as we are concerned unless we hear otherwise, any former Riesel sieve k is now shown as (available) for coordination, sieving, and testing here unless another effort starts up somewhere else.

If anyone knows of any effort anywhere else that is under way to continue on the Riesel base 2 conjecture, please let me know. Also, if anyone knows more up-to-date test limits on the various Riesel base 2 k-values, please let me know. If either affects what is shown on the pages, I'll update them quickly.

Thanks,
Gary

Were there 65 k's remaining? I was trying to figure this out myself.

Hello Gary

I obtained this information on dc.rieselsieve.com, and one of those using the message board there did send me the .dat file. From that I removed the k that was found prime after the date of the dat file. This made me end up with following 64 k's remaining:

Code:

I was able to make a list of all remaining k/n pair which were held by the dat, I can compress this output file and e-mail it to you, so you can start running a LLRNet client or something, if you're interested

Hope it helps!

KEP

Ps. There is about 3.2M untested k/n pairs left in the dat file, above n=3.42M (test limit mentioned on the dc.rieselsieve.com forum).

No, there were 64 k's remaining.

On my web pages, I show 66 k's remaining because for all bases here, we include multiples of the base that have not yielded a prime for n>=1. For riesel base 2, there are 2 even k's remaining that Karsten (kar_bon) is working on.

Great!

KEP, can you send me the .dat file in an Email? I'm sure it is huge. I'm not sure how it is sorted but if you can break it up in some logical fashion; perhaps one file for each 3 k's or one file for each n=1M range, that might help. Alternatively, is there a link where I can get the file?

Also, can you refer me to a link or otherwise let me know what the exact test limits are (i.e. n-range completion limits) for all of the k's here? I need to know the n-value where there are ZERO k/n pairs below that n-value remaining to be tested.

If people are interested, we could break up the .dat file here and start a drive to begin crunching again. Somebody please let me know if that would be politically incorrect. I don't want to start any wars.

In looking at the Riesel Sieve threads, it appears the admins there aren't interested in responding to people in a timely fashion even though they say some things are 'in the works'. So they really don't look serious in getting a stable project running again.

I did not send you the .dat file in the e-mail sent to you, however I did send you the finished output file. In a few I'll send you the .abcd file, which I created, which has made the output-file that I did send to you. It turns out, that the way the .dat file from RieselSieve is formed, srfile were impossible to use, so I had to do some search and replace, to get the proper coding in order to change to .abcd coding. The file I sent to you, is containing all k/n pairs not yet factored, even though they are LLR-tested at least once. The testing limits you show, should maybe be increased to at least n=2.9M, since (if my memory is correct) boinc.rieselsieve.com showed something with 3.1M n being the lowest n availeable on their stat charts. So in order to not miss anything, I suggest that ALL 64 availeable k's is being tested from n>3M except the k's with test limits n>4M, it should be sufficient to test those 2 k's from n>4M, and still not miss a prime.

Unfortunantly in only few words on: http://dc.rieselsieve.com there is described a test limit by bryan at 3.42M, however this is much higher than the numbers BOINC ever got to, so I'm not sure if any k/n pairs could be left behind untested, going from that depth and up.

This sadly is all I have, but I greatly appreciate your effort on getting this conjecture running again. Not sure if you collide with Bryan and any of his efforts, but do not expect anything else than empty promises. Several weeks ago he promised to get back to me and Rytis on setting up the base 2 Riesel conjecture and run it using PG, no replys has come to either of our e-mails yet.

As said, as soon as I'm done checking the remaining posts, and getting my last fix before going to bed, I'll send you the .abcd file, I used the -G to create the output file, if you want an seperate output file for each k, just use -g... well I'm shure you know about that and finds your own solution :)

Best of luck

Kenneth!

EDIT: I suggest a vote, that we vote "yes" or "no" to officially strip the RS project any ownership of this conjecture, so we can get things working again. In response to em99010pepe, it just verifies that nothing has really changed at RS since they gave up getting back online months and months ago :(

2. EDIT: No Gary, there is no way to download the .dat file, unless you knows someone who sieved using BOINC and who is willing to send you the .dat file on e-mail, like I just did :)

LLRNet RieselSieve server at dc.rieselsieve.com, port 7000, is down so it's better to set up a new one.

gd_barnes · 2008-09-23, 23:14

Oh wow guys. Perhaps some could view me as having done politically incorrect stuff in the past but this would be the biggest of them all! lol

'Stripping RS of any ownership' of the effort and taking a vote HERE to do such a thing would be tantamount to a big fight that I don't want this project involved in. I'll avoid anything of that nature.

What I'll do is put a post or 2 in the dc.rieselsieve threads. What I generally do in situations such as this where people are not responding or are dragging their feet on efforts or reservations is to ask for specific estimates and time lines.

Here's what I want to see: I want to see exactly what it is they need to fix their site. That is: an exact plan of action, realistic dates for accomplishing each item within the action plan, and a realistic completion date. Then, as the date for the first item in the action plan is nearing, I follow up to see if they are still on target. In effect, I become a quasi project manager just like in the real world. lol

If they can't provide such a detailed plan within the next 3-4 weeks, THEN the project should be considered dead.

What I'm hoping is this: If another project comes in and is potentially in a position to take over their effort, THEN they may actually get moving and get things fixed. We'll give them that chance first.

I'll go ahead and update all the ranges that are n<2.9M to n=2.9M in the next few hours. Expect to see a couple of posts in the dc.rieselsieve threads by mid-morning GMT.

The gauntlet has been dropped:

Limits also requested:

If they don't restart the RS project, I hope we can get more accurate limits.
