2023-05-26: LODA, Project update: 120k programs milestone reached!

We celebrate a new project milestone: more than 120k programs and 47k formulas for integer sequences have been found so far. A big Thank You! and shout out to all contributors of the LODA project!

During the last weeks and months, the mining rate (number of found programs) decreased, but we maintain a steady pace. At this point it is difficult to estimate how the rate will develop. During the last days we found many new programs for decimal expansions of log-constants. This is encouraging as we hope to find more programs for decimal expansions of irrational numbers.

In terms of tooling, we spend quite some effort in machine-learning and GPU-based program mining. These approaches yielded already some first findings, but they are still in an experimental phase and not ready for an integration in BOINC. In the coming weeks, we plan to invest more time again into our core mining app to increase the mining rate and improve the quality of the existing programs. Please continue your support for the project!

2023-05-25: SRBase, base R622 Megaprime / proven

IDEA, a member of the team Idea Digital Imaging found a megaprime for base R622.
The prime 78*622^402915-1 has 1.125.662 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database. With this find it is also proven the base!

2023-05-24: SRBase, new v28 apps update

The new linux wrapper is now updated for all srbase apps.

Also a new compiled llr2 version with latest gwnum30.12 for windows is up.

2023-05-21: SRBase, new linux wrapper test

If you want to participate in this beta test pls choose Sierpinski / Riesel Base (beta test) and "Run test applications" in your account prefs.

The new linux wrapper has more output in stderr.txt similar to the windows wrapper.

test_a_WU will do an invalid test
test_b_WU a short valid test

The deadline is only 30min.

An extended test will follow after this.

2023-05-12: NumberFields@home, Batch Plan

Some of you may have noticed, the search over subfield 7 DS16x11 is coming to an end, and you are probably wondering where we go from here.

We are going to start by making a quick detour to subfield 6 and start the search over DS11x12. The only reason for doing this is to keep the WUs consistent for the BOINC Pentathlon (timing stats for the 2 searches are very similar - WUs average about 2 hours on my CPU)

After that we will go back to subfield 3 and finish that search once and for all.

Then it's back to the final part of subfield 7, and then finally subfield 6.

2023-05-11: yoyo@home, Amazing ECM factor!

User Favebook found a 77-digit prime factor of an Homogeneous Cunningham number using ECM. This is by far the largest factor found anywhere by ECM this year, and is the 4th largest ever. Very exciting!This was a very lucky find (about a 1 in 28.3 million chance for a single curve).

2023-05-08: MilkyWay@home, Server Shutdown (5/8 - 5/10)

Hello everyone,

RPI is conducting their annual CII power maintenance between May 8th and May 10th. As a precaution, we will need to shutdown the server during this time.
We will have the server back up and running as soon as possible.

Thank you,
Kevin

2023-05-05: yoyo@home, 2 factors found by Pentathlon

The next 2 factors were found by the BOINC Pentathlon, a 55 digit factor by JayPi2 of team SETI.Germany anda 58 digit factor by biodoc of team TeAm AnandTech.

All CPU projects only, TF will not be counted in this challenge.

2023-05-01: yoyo@home, Welcome Pentathlon

The ECM and ECM P2 projects were choosen by the BOINC Pentathlon in the discipline Obstacle Run. Many user are already downloading lot of workunits and some return already. Credits are not yet counted for the Pentathlon, but we already have a noteworthy result, a 65 digit prime was found. This was sent to Paul Zimmermann to fill his list of ecm records.

2023-04-29: iThena.Computational, [April 29, 2023 to May 7, 2023] Planned maintenance breaks

We are scheduling project outages from April 29, 2023 to May 7, 2023.

These will be temporary access issues.
Sometimes these interruptions may last a few hours at most.

2023-04-29: BOINC, It's time to retire BOINCstats classic.

BOINCstats classic has been lingering around for those not getting used to the new layout. However, as I have said before, I'm no longer maintaining the code for it and it's beginning to show its age. To keep up with all the security risks (and bugs) I would have to maintain two separate code bases and besides not having the time for it, I just don't want to.

So, starting in June, BOINCstats classic will redirect to the current BOINCstats, meaning of course that it will no longer be available.

2023-04-28: Universe@Home, Project maintenance

I have just received confirmation that on Thursday, May 4, I will be able to carry out work with the project servers.
Therefore, you can expect short-term interruptions in its operation between 8:00 - 16:00 CET

2023-04-28: TN-Grid, Maintenance (filesystem and o.s.)

Right now that our queue is empty it is the perfect time to switch our filesystem to the new one and to upgrade the operating system of the server. This will probably happen the 2nd of May, for a couple of days. During this period the server may be down for awhile. After that, if everything will go smoothly, we plan to start distributing work again.

Good luck everyone!

2023-04-11: DENIS@Home, Status of the project // Estado del proyecto

Dear volunteers,
We update you on the status of the project and how the simulations are going. In recent weeks the search algorithm has been improving the model very little. This indicates us that the optimization is close to be finished. Once this is complete we will pass to the validation phase which we will be done outside of DENIS (DENIS is not yet prepare for the required simulations).

The improvement obtained is very considerable (you can see the graph with the evolution of the error below and we hope that the validation results turn out well). It can be improved, but not all the error can be removed with the optimization (it requires other type of improvements in the model).

On the other hand, looking at the results, last week we started a new optimization by changing an aspect of it. In the initial search, if one of the markers was in the experimentally observed range, we did not allow the algorithm to search where that marker was outside of the experimental range (criterion of keeping at least those markers that were already in the experimental range). In the new search we are allowing it in the hope that even if some marker goes out, the overall behavior will improve. In this case, the uncertainty about the result is higher, but as you can see in the graph below, after the first iterations of the algorithm, the results are quite promising.

Sincerely,
Jesus.
