Yesterday, on August 8th, a minor milestone was passed. The last of the early long WUs which were below world record size finally was validated by a wingman. That WU was initially sent out on March 4th, and the initial result has been waiting for verification since March 11th.

With that WU out of the way, the smallest outstanding WU is now larger than the current largest known prime number, so any prime found with the WR WUs is guaranteed to be a new world record prime and not "merely" a world record GFN prime.

Good luck everyone!

At first I thought you were referring to this tortured WU, which I put out of its misery a couple of days ago. It had been waiting almost as long.

Thanks for the encouraging news though! Good luck to all.

The first post talked about the 'trailing edge', i.e., the smallest WU that was still in progress. Here's the "leading edge", i.e., the largest WU currently being worked on:

As of right now, the leading edge of the GFN-WR search is at b=5774.

5774^4194304+1 is 15,776,778 digits long. This WU is worth 342,298.37 credits. The estimated amount of computation required to test this number is 369,682,242 GFLOPS. (369 million billion floating point operations)

The current largest known prime number is 2^43112609-1, which is 12,978,189 digits long.

This sounds a little too high. How did you calculate this figure?

However, since the GPU has fewer DP units that shaders, although it's running at "99%", it's likely only running at fraction of that. So the actual number may be 4 or 6 or 12 times lower (whatever the penalty on DP vs SP is on 400 and 500 series GPUs).
