SRBase - 3 years review
The project has passed the third year.

Compared with last years the following process was made:

2014-2015 - 87M WUs processed, 1 base solved, 314 bases unstarted
2015-2016 - 88M WUs processed, 5 bases solved, 297 bases unstarted
2016-2017 - 99M WUs processed, 5 bases solved, 282 bases unstarted
in total - 274M WUs processed, 11 bases solved, 282 bases unstarted

The computing power was beyond the 40TFLOP mark. KEP is still working on a more precise stats overview and will be released maybe in January 2018 so stay tuned.

The next upcoming llr app will have a new gwnum lib with full AMD Ryzen support but I dont know when it will be released.

Due the lack of available sievefiles there are some gaps in the work generation. The remaining primes for these bases are very high, the tests are going over a million. The project cannot handle so many files into one folder thats why they must be splitted into some batches.

The yoyo@home project took over the sieving part for CRUS / SRBase. More and more new sievefiles will be available in the future in a short time period. If you want to help there enable sieving in prefs.

A big thx to the Gridcoin team for the amazing computing power in the past months and of course all the other users / teams spend their power to bring the project forward.

For those who are interested in the public paper for SRBase this is now ready for download.. I will add a link on the frontpage soon. If you have any questions about it let us discuss this in the forum.

Looking forward...

base S263 cancelled (average app)
I have forgot to change and removed all WUs, 200 WUs were sent out before I noticed that. Please abort all of this batch. Sorry for the trouble. 12 Nov 2017, 17:47:43 UTC · Comment
