[PrimeGrid] AP27 Found!

On 26 May 2023, 01:04:36 UTC, PrimeGrid’s AP27 Search (Arithmetic Progression of 27 primes) found the progression of 27 primes: 277699295941594831+170826477*23#*n for n=0..26 This is the second known AP27. The discovery was made by Tom Greer (tng) of the United States using a NVIDIA GeForce RTX 4080 on an AMD Ryzen 9 7950X CPU @ 4.50GHz running Microsoft Windows 10 Professional x64 Edition. This computer took about 4 minutes and 22 seconds to process the task (each task tests 100 progression differences of 10 shifts each). Tom Greer is a member of the Antarctic Crunchers team. The AP27 task was double checked by Vasil Zakiev (zvasi_000) of Russia and was returned on 26 May 2023 01:04:39 UTC. This task was run on an NVIDIA GeForce RTX 4090 on an AMD Ryzen 9 7950X CPU @ 4.50GHz running Microsoft Windows 11 Professional x64 Edition. The double check took about 1 minute and 27 seconds to complete. Vasil Zakiev is a member of the Crystal Dream team. For more details, please see the official announcement.

[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!

[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.

[Quake Catcher Network] End of QCN

I am relaying this important message from QCN management at EarthScope. You may have already received this message as an email if you are registered in our database as a QCN station user.

The QCN program will end as of June 1, 2023. We are committed to do our best to keep the QCN software running through that time, and after that time the server will be decommissioned as the program sunsets.

We appreciate your engagement in this program through the years. We know you will be interested in continuing to include seismic data in your teaching. Thus, we encourage you to explore our educational software package jAmaSeis (https://www.iris.edu/hq/jamaseis/) which allows classroom access to real-time seismic data from research quality stations from around the world and other commercially available sensor options, a primary example: Raspberry Shake (https://raspberryshake.org/) if you would like to continue to record seismic data locally. There are other educational sensors on the market, and we put significant effort into being able to stream the data from available sensors through our products.

Please reach out if you have any questions.

[TN-Grid] The new Vitis vinifera project is underway

Dear all, I am very excited to announce that a new bigger dataset of Vitis vinifera transcriptomic data (Vespucci) is now available for OneGene expansion. The number of experiments has more than tripled. We are still using the results from the previous analyses, finding very interesting gene associations and producing amazing gene networks. We now expect to improve and refine them with this new collection of runs. Many thanks to all of you.

[[email protected]] 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.

[[email protected]] 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).
