In a few hours, the Wieferich search will go beyond 1e17. That is 30x further than had been searched in the decades leading up to this project. Unfortunately, Richard Crandall, who was the inspiration in the search for Wieferich primes died in late 2012. He would have been very happy to see the success of this project.
Thanks to everyone who has dedicated computing resources to this project. Thanks also to PrimeGrid for hosting.
1e18 is the next major milestone for this project, which I estimate to be about three years away. The current software is closer to 2^63, which is about 9.2e18, so we have a long way to go. | |

Does that sentence mean that 9.2e18 is the upperbound that the current software can search to?

Yes. | |

The "Completed Thru" stat on the server has passed 2^57. That is one milestone.
A more important milestone will (to me) be Pervushin's Mersenne number 2^61-1 (proved prime in 1883).

Yes.
Rogue, do you know what is the limit for WSS?
Thanks | |

wwww and wwwwcl should be able to search up to 2^63. It would have to be rewritten to go beyond that value. | |

On windows 7 64bits running amd 7970 latest driver and 5.3.1 of the client I again am getting this error - I thought there was another version of wwwwcl
that was working with amd, just slower. If so could I get that link?

Thank you rebirther!
Seems on my system if I try and run the GPU above ~92% the driver will crash.
So I tweaked the wwww.ini file and running 2 threads and only 500 blocks the gpu stays around 85% and still does a unit every 120 seconds. I can live with that until the fix for opencl (if ever).

Does Weiferich take longer than Wallsunsun? With wallsunsun, I got around 37 seconds per WU. Now that I switched on Weiferich, they're taking 100 seconds or so. GPU usage is very erratic, never above 90 though... They both had the same settings, same GPU,,

Threads: 8192
Threads: 4
EDIT: Just realized it uses around 3 full CPU cores.. That's why gpu usage was so low. Better now, between 90 and 99% gpu usage, still very irregular. Now they're taking around 60 seconds... Still significantly longer than WSS.

The work units for Wieferich are larger (10x IIRC) than WallSunSun. | |

Yes, Wieferich has always been more time then Wallsunsun. | |

Wieferich is currently searching in the 18-digit range. WallSunSun is currently searching at 17 digits, and thus, is smaller (and shorter to compute) than Wieferich.

Oh, okay. Does it grant more credit, too? (Just wondering.. Still going to run it either way)

Today, during the September 2014 challenge, the leading edge has passed 2^58, so we are now crunching 59-bit primes.

The "Completed Thru" stat on the server has passed 2^57. That is one milestone.
A more important milestone will (to me) be Pervushin's Mersenne number 2^61-1 (proved prime in 1883).

In a few hours, the Wieferich search will go beyond 1e17. That is 30x further than had been searched in the decades leading up to this project.
...
1e18 is the next major milestone for this project, which I estimate to be about three years away. The current software is closer to 2^63, which is about 9.2e18, so we have a long way to go.
Before 2014-08 challenge, leading edge was 1.5e17.
After latest challenge, Wieferich leading edge is 3.2e17.
This has significantly surpassed expectations and is approximately as much work as done ever before.
Great job, everyone!
