What are your BOINC and SRBase projects that you are talking about? Will you be reporting all primes here and any top-5000 primes with CRUS as the project?

For any testing n>25k, please also send the residues.

Rebirther has set up a BOINC project, to help CRUS. You can see further [URL="http://srbase.myfirewall.org/sr5/index.php"]here[/URL] :smile:

I think Reb is clear on the procedure, however it's always nice to check in advance, such that all get their appropriate credit. However this SRbase BOINC project is only going to work on CRUS bases, so maybe in the future a merge could be done or a rename of SRbase to CRUS@home or similar. The naming is up to Rebirther, however I'm glad that we finally get a BOINC project dedicated to support our effort.

Take care

Yes, will do, the first run has some compressed files in zip too (around 6800) so I need to figure out how to put all the residues in one file. For your first question of course I will reporting all top 5000 primes here and you can report it to the primebase with CRUS if you want.

[QUOTE=rebirther;388919]I have asked KEP and spoken in detail. Sorry if I missed someone.[/QUOTE]

KEP is not an admin for this project. In the future, you need to check with admins. Since you did not go through proper channels, this has an air of hijacking the project.

I expect that all statuses and residues be reported here and that all top-5000 primes be reported here and at the top-5000 site with CRUS in the prover code. It will be your responsibility to make sure that they are all reported properly.

I have informed Rebirther by PM that we are OK with the BOINC effort to extend some of our bases. I have requested that he restrict the BOINC searches to n>50K to avoid overwhelming us with 1000s of small primes. It will be interesting to see how this plays out.

My anti-virus keeps stopping me from going to this site. It says it is malware. I have to turn off the anti-virus in order to access it. I've attempted to add the site to the exclude list but it keeps saying it's malware. Is anyone else having this problem?

It makes no difference. It still rejects it. If the site is hitting people's anti-viruses it's not going to be very popular. I'll keep playing around with it to see if I can it to quick rejecting it.

I am using AVG and I have no problem.

is it when you are downloading app. or when do you get rejected by antivirus software ?

Lennart

In the past when we talked about going BOINC for some of the heavier bases I usually thought PrimeGrid. Lots of computing power there. But it's nice having a dedicated project and not being one of several subprojects for PG.

Depending on how this evolves it might become a challenge to provide enough sieve files. I'll do some sieving if needed. Which bases should we try to BOINCify? My suggestion would be stuff that nobody wants to tackle on their own like R19 and the like.

I'm glad that you have told Rebirther by PM, that you're OK with the BOINC effort. Your previous post, to some extent offered the suggestion that you and propably also Ian missunderstood the purpose of the BOINC server. Personally I don't really see a problem with someone setting up a BOINC server to support CRUS, even without asking in advance. We all have to be realistic and time is more or less running out for CRUS as a non BOINC project, if we want to see any noteable progress on most of our bases. As long as srbase project doesn't reserve all aveilable k's for all started bases, then the BOINC effort should never for one, be considered/viewed as a hijacking of CRUS.

Untill rebirther get's sieving to work (if he ever decide to offer that through BOINC), then the biggest problem with going BOINC can be to have enough sieving power. However PuzzlePeter and Lennart may be able to ultimately cure that problem, given that Lennart would also join the sieve effort. On a sidenote, if it is decided to take up the effort of taking R256 from current minN to n=750K, then there is plenty of work for thousand users, at least for the time it takes to optimally sieve one or more conjectures :smile:

Well just my two cents, and on a very final note:

No I'm not an admin and I do not expect to ever be, however I have for long desired to see some part of CRUS be offered to the BOINC community and therefor I started discussing the possibilities with Rebirther. I guess next time, it may be correct to ask the moderators/admins first and I appologize if anyone is offended by Rebirthers tremendous work.

Take care

I had not added it properly to my exclusion list. My anti-virus no longer blocks it. I don't know why it did to begin with.

Reb,

Since you have only done Riesel bases up to this point, I'd like to request that you also do Sierpinski bases in the BOINC effort. To the extent that it is reasonably possible, we try to keep both sides about equally searched.

Gary[/QUOTE]

Yes, no problem, I will pick up another one soon.

As safety minimum quorum and initial replication should be set to 2.

Just stopped by the forum and noticed this...very interesting idea. I'm looking forward to seeing how this turns out going forward.

One thing though...I'm getting the same issue Gary had with antivirus (Avast in my case) blocking the link. For me, it happens whether or not the "index.php" is included. The reason for this is that "myfirewall.com" is (I'm guessing from the looks of it) a "Dynamic DNS" server, similar to No-IP and others, which is used to run servers on dynamic residential IP addresses - but also heavily abused by bad guys running botnets and such. Some dynamic DNS providers are more heavily abused than others; the "better" ones shouldn't be blocked by antivirus.

NPLB/CRUS used No-IP for a long time in our earlier days before Gary got a business class connection, and we never had an issue with antivius blocking us. I would [i]highly[/i] recommend checking them out as an alternative (it's free, and you could still leave the current address active as an alternate address). Otherwise, you're going to have a serious problem advertising and gaining participants, because if major antivirus products are blocking you (the one I use, Avast, is very popular), that's a significant portion of the Internet that simply can't reach your site.

I can also recommend other good (not typically blocked) dynamic DNS services if you're interested - I use a couple of them for my own network.

I also have Avast. The best free anti-virus out there.

Is there no option in the antivirus programs to set the site on a whitelist?

While that works for regulars who already know what your project is doing, it's not going to get you new users from the greater BOINC community- that's the problem they're trying to address.

Yes, Curtis's response is the point. It took me a little while to add your website to the exclusion (white) list on my anti-virus so that it would not block it. I barely know what I am doing and it took 2 attempts and about 15 minutes of my time. For people who don't know how anti-virus's work, you will likely lose them as potential searchers because they are unable to reach your site.

Lennart

Yeah, the instructions are not clear ...
You have to goto the website first, attempt to login, and then it will let you create an account.
That's when you use the invite code...
After that's done, then you follow the directions to add the project to your BOINC manager.

Ah that's good for us "early adopters" as it allows us to race ahead in the BOINC stats :)

Only problem I've had with this new BOINC project is that they run out of work too often. Primegrid never runs dry.

With respect to Sieving, PG also allows us to sieve using our NVidia GPUs. Dunno why Rebirther hasn't set that up for SRBase yet.

[QUOTE=vaughan;391456]With respect to Sieving, PG also allows us to sieve using our NVidia GPUs. Dunno why Rebirther hasn't set that up for SRBase yet.[/QUOTE]

Well GPU is propably never gonna happen at SRBase, since the work that CRUS does is using either srsieve, sr1sieve or sr2sieve for sieving. None of these 3 programs has been ported to any GPU system. Last I heard of it, the problem is not with the applications themself, but with the required memory getting bigger than the available memory in the GPU.

KEP

OK thanks for the info KEP.
It appears that SRBase is attracting some crunchers who wouldn't normally be seen on any of the non BOINC math projects. I think its good to see some activity.

[QUOTE=vaughan;391529]OK thanks for the info KEP.

It is very good, because even though we are a few very dedicated crunchers at the mersenneforum, then weather we like it or not, our resources is getting stretched more and more thin, so it was about time to go BOINC if we would like to see all the started base move towards significant levels, within reasonable time. Eventually not even BOINC will be able to run out of work, because the n-range and the amount of remaining k's in a high-n level is going to be many enough to keep a sustainable flow of work at BOINC, weather or not sieving is implemented at srbase.

KEP do you mean like 17 or Bust and its incredibly long running tasks?

Personally, I cannot stand such long runners and I'll switch to another project. For example, in November and December I was running a project called BOINC@Fiit and I had some tasks that ran for over 1000 hours. One completed OK but I lost the other two I was running on a different PC as I inadvertently re-booted it. The stupid project doesn't have checkpointing enabled so I lost all that CPU time (and electricity). Consequently, I'll never run that project again.

Well eventually yes, but because CRUS is spread over 1031 bases on the Riesel and 1032 bases on the Sierpinski side (2063 bases in total), then there will for the next hundreds of years, be the possibility of offering work, where the test completes in just a few minutes.

For the bases with a low conjecture (conjectured k<=10K), it is most likely, that computation time required per test, will eventually reach the times that you currently see on SeventeenOrBust since the increase in computation speed will not be able to keep up compensating for the increase in the size of the numbers tested.

So as you can see, Rebirther has the possibility of offering plenty of small workunits, it may very well be so for the next hundreds of IRL years of using BOINC, before all 2063 bases reaches an n level where testing time will frequently be above 1 hour.

Another fact is that it may very well be several decades before all bases<=100 is tested to n=25K.

Personally I hope that Rebirther will eventually offer very long tests, since that will attract some entirely new kind of users. But who knows, what the future will hold for us :smile:

I think it would be best to offer two or three subprojects so users can decide which runtime they prefer.

[QUOTE=Puzzle-Peter;391600]I think it would be best to offer two or three subprojects so users can decide which runtime they prefer.[/QUOTE]

I very much like that idea, maybe it should be six, such that people can choose as follows:

Sierp short
Riesel short
Sierp
Riesel
Sierp long (day/week/month+)
Riesel long (day/week/month+)

That all sounds very good to me. :-)

Is the BOINC server down?

[QUOTE]Is the BOINC server down?
[/QUOTE]

Server is not ours. Belongs to Rebirther somewhere, I think, in Germany.
It does seem to be down.

The choice / decision to select short or longer tasks is available (when the server comes back up) by going to the project's preferences in Your account, in the project's site.

Personally, I unchecked the long tasks. Happy to run the short tasks for a few hundred years :smile: as long as they award cobblestones at the rate they have been issued recently. Its become one of the better "paying" projects. Nowhere near Bitcoin Utopia but then I only have a few ASICS devices running that.

[QUOTE=vaughan;391794]... as long as they award cobblestones at the rate they have been issued recently. Its become one of the better "paying" projects.[/QUOTE]
Ah, I see now what [I]really[/I] matters.
So, tomorrow, PrimeGrid will decide to give 20% "bonus" cobblestones on everything - and you will switch to them.
To retaliate, CRUS will double the issued cobblestones - and you will switch back to them.
Then, PrimeGrid will triple cobblestones - and you will switch back to them.

Nice! I wish real-life people were so easy to manipulate with a carrot. Oh, wait... they are!
But in real life, they are not paid with "air", so inflation and the need to trade using the currency of the seller keeps the monetary system away from insanity. Barely.

Seriously though, if CRUS BOINC is (because of their young age) issuing [URL="http://en.wikipedia.org/wiki/BOINC_Credit_System#Cobblestones"]unreasonable amount of credits[/URL], they should rethink their position pro-actively. Before other projects contact them to ask about that.

Rest assured, we're not going down that road!

I think Reb is simply struggling with the whole credit thing, trying to set the proper amount. It's not easy to do with LLR, and he's not in a position to use the system Jim and I set up at PrimeGrid.

The funny thing is, unless I'm remembering it wrong, when I ran a few of the tasks over there the LONG tasks were yielding more credit per hour. (It's actually a good thing to bias the credit that way since people prefer short tasks.)

It has always astounded me how big a motivator the competitive spirit is. Give people a scoreboard and they'll cross heaven and hell for you, merely to get a higher position on the board.

It's a great way to solve those big conjectures that need several millennia worth of cpu-hours to crunch all the numbers. :)

[QUOTE]It's a great way to solve those big conjectures that need several millennia worth of cpu-hours to crunch all the numbers. :) [/QUOTE]

And we haven't started the BIG ones yet. There about 20 or so bases still left to start that make R3 look downright
puny.

[QUOTE=AG5BPilot;391815]Rest assured, we're not going down that road!
[/QUOTE]
I know! I was merely trying to make a point by exaggeration ;-)

I have not yet mentioned the infamous example of mersenneathome.com - they gave high credits, they had decent participation, they listened to no one (believe me, for my part, I've tried and tried and tried to get their admin to think). The trouble was - they were doing absolute bull:poop:!! Did it matter to their contributors? Hell, no! "Just give us a scoreboard", absolutely right you are. ...but then again, just give mother nature some time and evolution takes care of any weird mutants. They are long gone, and I have no tears to shed.

Tangentially, the ASIC credit, though poorly understood by some, is probably fair to the BOINC standard. ASICs are simply insanely productive (by objective dhrystones or whatnot) - but of course for one single particular task at hand. there are in fact amazing side products of their mining. Honestly, I think some of long k-tuplets found by them are quite spectacular - [URL="http://anthony.d.forbes.googlepages.com/ktuplets.htm"]here[/URL].

Last thing (the "Graduate" moment, so to speak), while someone is reading this... I have but one word to say to anyone who is interested in a good investment for the future.
[STRIKE]"Plastics"[/STRIKE] ... [B]"Cyclo!" [/B]
All ingredients are in place! It is time to start the uwine/primesearch folders for Cyclo_N=16...22, send out announcements, and then, sometime soon start Cycl-ing! All the GFN people who are now hitting their B limits will be only too happy to switch.

P.S. This reminds me to give Riecoin some competition. They haven't advanced the sextuplet record so far that I couldn't potentially beat that (because I found quite a nice template for them, which no-one used before: k * p# / 2 + d, d = −8, −4, −2, 2, 4, 8 ...and all I spent was probably a day or two, back in 2013)

I sort of understand what you are saying about the points Batalov but to be fair my BOINC stats reveal that I have put in a reasonable amount of work on under-paying projects: Leiden Classical being a good example.

I agree PG can be a good payer for some sub-projects and it still has my all-time favourite GPU crunching application for nVidia GPUs PPS_sr2seive which accounts for 789,904,021 points out of my total 835,940,884 PrimeGrid points (at time of posting).

[QUOTE=rebirther;394112]Reserving R79 to n=100k (25-100k) for BOINC[/QUOTE]

Suggestion for BOINC:

Stop R79 when it reaches n=50K (> 7000 k's remaining). Instead search R19 for n=50K-100K (1216 k's remaining).

Reasoning: Excluding huge bases 3/7/15, R19 is the only base < 35 that has not been searched to n>=100K and a sieve file is available.

Another nice candidate (not <35 though) would be R40. I thought about giving it some more sieving but I soon realized the file is fit to start LLRing.

As long as the suggestion box is open, I'd add R39, S39 and S40. R39 alone has over 8M tests in 7 sieve files.
It would also move the bar up to >41 as far as tested to 100K (on both sides).

BTW: A nice job being done by all on BOINC. Over 200 active users and 4200 active ports. Zowza!!!!!

Yes I would prefer stopping R79 at n=50K and advancing R19 to n=100K if that is OK with you and the BOINC folks. I'll leave it up to you whether you run R19 to n=100K and finish R79 to n=50K at the same time.

I can also finish the R79 to n=100k. But if you cant maintain it I will stop at 50k. I will release the rest of the sievefile then. There are around 15M tests left. R19 was started from 50-60k now.

That would be great if you could stop R79 at 50k. Thanks.

I added R35 to n=100K to the BOINC list. Finishing all of those would bring all bases < 50 (sans 3/7/15) to n=100K.

Suggestion for future: Some of the lowest difficulty bases as shown at the bottom of the unproven conjecture list at [URL]http://www.noprimeleftbehind.net/crus/vstats_new/crus-unproven.htm[/URL]. I've been working on some of those myself lately. They are the easiest to move forward and are generally behind their neighbor bases with similar #'s of k's remaining on search depth.

R19 seems like an interesting base for BOINC work in the medium term. Once it is complete to 100k, would BOINCers test 100k-250k if I make a sieve file? It would take me 30ish days to sieve fully, I expect. Is that worthwhile?

Thanks for the offer. I'm not stopping the BOINC effort from doing what it wants but I'd prefer that it not take on such a large effort for a base with no chance of proof in our lifetimes. After some of the smallish bases < 50 with large #'s of k's remaining have been searched to n=100K, I feel that the huge resources needed to search them higher would be better utilized in some of our high-n searches on bases with few k's remaining that have a reasonable chance of being proven. If you'd like to help sieve, consider taking our Sierp base 6 n=1M-2M file (12 k's). A link is on our reservations page. It is already sieved to P=220T. That would be the kind of effort I'd like to see BOINC go after.

I prefer to help on Riesel bases. Does R30 fit your criteria? 9 k's, at 500k now, unreserved. If I built a sieve file for 500k-1M, would BOINC test it?[/QUOTE]

Close but how about R28 instead? 4 k's for n=500k-1M. It's currently tested to n=450k by Ian and he should be done to n=500k anytime now. Another good one would be R37. 16 k's for n=100k-250k. I tend to look at the bases with lower relative difficulty (to catch them up so to speak) as shown at [URL]http://www.noprimeleftbehind.net/crus/vstats_new/crus-unproven.htm[/URL].

[SIZE=1]Of course not stopping anyone from doing whatever he wants to do.[/SIZE]

Should be done in about 2 weeks.

OK. R37 is a smaller sieve project anyway, in case I lose interest before a 500k-1M sieve is done. I'll start this in a few days, 100-250k.

For BOINC ranges between 25-200k are good at the moment. If someone want to sieve some bases in the list 10-25k or 100-200k with some smaller k this would be fine. So we can combine the power by sieving, starting new bases up to 10-25k and BOINC is testing 25-200k. At the moment the rate of 4.6k tests in progress are low. My goal is 10k. Iam always open for some wishes what bases are run first.

Are you suggesting I sieve 100-200k rather than 100-250? In the long run, this is fine, as the next sieve can be 200-500k to hit the usual next milestone. Note that base 37 is pretty low, so the tests will run quite a bit faster than bases over 100- meaning 250k isn't unreasonable.

For the smaller bases you can sieve up to 500k.

Attached is the sieve file, with just under 42000 candidates, for base R37 from 100k to 250k. Once you finish this file, I'll sieve the remaining k's to 500k.

I sieved to 5T. This produced a time per factor of just over 400 sec, with an LLR test of the first candidate taking 125 sec on the same machine.

Rebirther-
If I sieve R28 from 500k up, how high are you/BOINC willing to test? I'm thinking 750 or 800k would be enough chance to find a prime to make a sieve worthwhile for me to build, with the leftover sieve posted for someone to take on afterward.

The R37 sieve 250-500k is at 19T now, stopping at 28T in about 2 weeks.

I always need the runtimes on a based CPU to know where I can put it in. Small runtimes up to 30min are good.

For base 37, 30 minutes is around 400k on my haswell-i7; so 500k will be a bit longer than 40 min (extrapolating from my tests with 100k to 200k candidates on the previous base-37 sieve).

MyDogBuster can tell us exactly what time base 28 @500k took, but it should scale with the square of the base (?) and thus be about 60% the time of base 37. If my estimates are correct, that's around 25 min for 500k, 50 min for 700k on a haswell. If you aim for 30 min or less, you won't test enough of base 28 for me to build a sieve for you.
Ian, can you confirm testing time?

About 29 minutes on a Haswell.

Just popping to say that I saw the SRBase project on the BAM! list of projects, thought it looked interesting. And then thought it looked really quite [I]familiar[/I], saw Gary's name, and realised that the project was actually part of CRUS! Very exciting!

I never was much good with running manual projects (I want to tinker too much :P) so I'm pleased to be able to contribute via the BOINC client. Admittedly, I'm running seven year-old desktop hardware (recently updated from decade-old desktop hardware!), so my contributions might be a little underwhelming. I'm hoping to upgrade to something from this decade at some point.

(I may have lost, oh, about an hour this evening catching up, or trying to catch up, on the status of the project!)

SRBase BOINC appears down....

Not sure how to contact Rebirther outside of this forum....

My cable provider is down, sorry. I have stopped the server. I dont know when its fixed.

No problems, thanks for the update! My secondary project is PrimeGrid. When SRBase is back up, I'll swap back.
