We are rapidly nearing the 100% mark! Since things are running very well and are yielding excellent results, after hitting this initial goal, the project will continue with a new-and-improved algorithm.
In the (very) short term, we will keep the current algorithm running for a while. Even though we will soon have reached our initial goal, the theoretical range up to which the current code can run is still a ways off, so we are still finding new triples.
Since around october 2008 we have been hard at work designing a new algorithm, incorporating new mathematical ideas and performance tricks. The result is an algorithm that is significantly faster than the current one.
The actual calculation code for this next run is almost complete and mainly requires some final performance tweaks and making sure it runs on a wide range of computers. I'm currently working on updating our backend code to generate and process the new type of workunit, and embedding the calculation code into a BOINC client application.
After that is done, our plan is to re-open ABC@home-Beta to do live testing of the new code. Since the basic infrastructure will be largely the same, I hope we won't need a very long testing phase. Assuming we won't run into large problems during testing, we will then distribute the new application to the main ABC@home project. This should take place sometime in february.
I'll keep you informed on the progress we're making in moving to the new algorithm. Many thanks for your continued help, and a slightly belated happy 2009!

Thanks for the news Willem Jan. When the beta project reopens, will it still be at http://abcbeta.math.leidenuniv.nl?

My wish list includes making this code CUDA compatible. GPUgrid were the first, SETI followed, and Einstein is in the works.
The performance gains for such a port, if applicable, is astronomical!

Yes, probably.

Yay!!! I'm excited. This is definitely one of my favorite projects.

/ how much work is there to do? because we are over 100%
thx
/ But what is the goal of the new algorithm.
I envision that you put the 100% goal a couple of years ago in the hope that at this point you would have enough evidence to tackle this ABC conjecture.
Is this not correct? Did the values not give you enough evidence or info to work with?
Or is the goal now to get hard proof that there is a limited number of ABC numbers for q > 1?
/ You'll never get hard proof when trying to solve a math-problem with "brute-force". btw, the 'goal which was set several years ago' isn't reached yet, they've decreased the goal (as showed on rekenmeemetabc.nl) several months ago.
/ You'll never get hard proof when trying to solve a math-problem with "brute-force".
I agree. They would have to prove that for every work unit the 2 computers that made the quorum did not make exactly the same "mistake" and fail to find an ABC triple. The odds are extremely small that 2 computers would make the same mistake but, unfortunately, the odds are not 0.
btw, the 'goal which was set several years ago' isn't reached yet, they've decreased the goal (as showed on rekenmeemetabc.nl) several months ago.
As I recall, the original goal was to search the number space 1 to 10^20 but the progress made in the early weeks indicated it would take 10 years to achieve that goal so they decreased the number space to 1 to 10^12.

We are over 100% of a reduced goal as stated below ...
The original search was to go through all numbers up to ten to the twentieth power and that was later reduced to ten to the twelfth power ... which is a significant reduction.
Though I would suggest that the estimate of 10 years was probably off by at least two years as computers improve in power and with growth in participants ...
So, for the original goal we are not anywhere close to the goal ... for the reduced goals we may be over that goal ...
Regardless of estimates of goals, we will continue to have work ... and that ain't half bad ...
I am sure I have SOMETHING wrong, but, I think I am close ... :)

Why, are you leaving just in case there might not be work to do? As long as there is work being issued I am staying, when my computers run dry I will add another project in and when ABC comes back I will then run that project dry manually and crunch for ABC full time on these pc's again.

I am not leaving, I just wanted to know when I have to do that what u described. I like ABC :)

There is at least 1 more year of ABC work coming. Very soon they will have to switch over to a new application to handle the new work. There might be a pause in the work when they switch to the new application or there might NOT be a pause. Nobody knows an exact date and time for when that pause might occur. You seem to be attached and crunching for Milkyway so it seems you are already prepared for whatever happens.

Yea I like it too! I am going to just play it by ear, I hope they do not have any long prolonged outage! Personally I do not have a problem re-crunching, for verification purposes, some old units. Just to make SURE we did them right the first time thru. The odds are very good they were all done right, but they are NOT 100%! A little fact checking, while getting ready for the next batch, wouldn't bother me at all.

I have been trying to ascertain what the latest status is by reading this thread and the two previous threads:
http://abcathome.com/forum_thread.php?id=80
http://abcathome.com/forum_thread.php?id=401
I understand that the intention a new algorithm is to extend the range being tested such that approximately one year will be required to complete the project. Is this correct?
Why does the home page at http://www.rekenmeemetabc.nl/ show that the project has reached 165%?
Has the original goal of 10^20 been reinstated?

Yeah Warped, good question.
I'm a new convert to BOINC - only joined a few weeks ago. ABC@home project looks really interesting, can the admins give us an update?
We don't expect you to be finished with the development - know this isn't all an exact science. (Pardon the pun!). Would love to know how you are coming along however.
Is our processing still worthwhile, with the old algorithm? How long until the new one is likely to be released?
Cheers!

Hello from Turku > Åbo
/ [quote]Ok, stopped then this project has finished?
No, not at all! In fact we are getting more results than ever before!
It is only the first version of the project which has finished, the "abc finder" (version 1.*). We're currently running the much improved "abc sieving finder" (version 2.*). We'll post some stats on the results that are coming in within the next few weeks.
The reason that the counter at rekenmeemetabc.nl has stopped is because it was coupled only with version 1 of the project. The maintanance of that site has fallen behind, and we will make it into a static site with a link to abcathome.com soon.
Thanks --Bart
/ Hi
Is there a problem with getting new work or has the project finished. I have had nothing new for 2 days now and the server giving out work seems to be "not running"

Please ignore. When my very last unit of work went in i got some new ones. Phew
/ Two of my computers have not been able to get works as of yesterday 26Jan10. Are we out of work???? Sometime today my 3rd computer will run out. If there is no more work Pls let us know so we can go to another project.
Thanks!
P. S. Don't worry I'll come back when there is work!!!

According to the Server Status link on the front page there are:
