BOINC effort for CRUS

[Puzzle-Peter]

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

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.

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 highly 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.
