Three new Einstein@Home papers
Three papers full of new Einstein@Home science are available now on the arXiv preprint server. [Link] First low-frequency Einstein@Home all-sky search for continuous gravitational waves in Advanced LIGO data describes our first results from a search in data from the first observation run “O1” of the Advanced LIGO instruments.[Link] read more
[wildlife] back up and running
Everything should be back up and running. Let me know if you're seeing any weird workunits (i.e., really long run times).
I'll also have an application update out tomorrow which should help track down some of those issues and improve reliability.

[wildlife] new app/type version 0.31 and an update
I've made an update to the application which I'm hoping will allow us to get even better results. Currently we've hit 99.45% on the MNIST dataset, which is actually quite good considering the current version of the application only performs convolutional operations and doesn't do any pooling. Here's a list of some of the best published results on this dataset:
And that puts is pretty solidly in the middle of the list. The new application now lets EXACT also evolve CNNs with pooling operations, which I'm hoping will bump us even higher up the list. This is pretty exciting as we're evolving the structure of the convolutional neural networks (CNNs) from scratch, and we're getting competitive with some of the best human designed CNNs. Anywho, let me know if you are having any errors with the new v0.31 applications.
On another note, I just returned from this years [Link] Genetic and Evolutionary Computation Conference in Berlin, where I presented a poster on this work. There was quite a bit of interest in this approach so that was really good. I just want to thank everyone again for contributing all your cycles to this work.

Dear VGTU project@Home users,
We have decided to stop the computations with the current [Link] application for dynamic visual cryptography based on non-linear oscillations. Some results have been obtained and published. However, new ideas are needed to move forward.
In the meantime, we have developed a new application in collaboration with our colleagues from the VGTU Department of Information Technologies. New application is solving the grillage optimization problem with parallel global optimization algorithms. More detailed description is [Link] here.
We thank you for your active participation and hope that you will find the new application also worthy of your computer’s time.
We have tried our best to test it. However, some undiscovered issues may appear. So, we will start with small portions of work.
With best regards,
The Project Team.

CMS Jobs working again
It's been a few hours now since the Data Bridge appears to have been fixed and jobs are staging out normally. You can resume running CMS tasks at your will.

Yet Another GFN-131072 Mega Prime!
On 15 July 2017, 21:04:54 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:
The prime is 1,005,326 digits long and enters [Link] Chris Caldwell's The Largest Known Primes Database ranked 24th for Generalized Fermat primes and 240th overall.
The discovery was made by Giles Averay-Jones ([Link] Dingo) of Australia using an AMD Radeon 7700 series GPU in an Intel(R) Core(TM) i7-4771 CPU at 3.60GHz with 16GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 41 minutes to probable prime (PRP) test with GeneferOCL2. Giles is a member of the [Link] BOINC@AUSTRALIA team.
The prime was verified on 15 July 2017, 22:10:39 UTC by Dirk Sellsted ([Link] Dirk Sellsted) of Canada using an Nvidia Geforce GTX 1080 Ti GPU in an AMD Ryzen 7 1800X CPU with 32GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 6 minutes to probable prime (PRP) test with GeneferOCL2.
The PRP was confirmed prime by an Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz with 16GB RAM, running Microsoft Windows 7 Ultimate Edition. This computer took about 2 hours 45 minutes to complete the primality test using LLR.
