I've started a bit late, but I'm in to.  Wu's seems stable on my machine.

Yeh I almost missed the start too. I thought it started tomorrow morning at 4am, not this morning. Only noticed by accident when visiting the PrimeGrid site to check on a long pending Seventeen or Bust task.

I like these short challenges, just a quick little sprint on one project and then back to your current project of choice.

No shortage of work or server trouble like last time. Stable as a rock on my computer and granting about 65 cr/hr.

Well done to all 11 Dog Days of Summer entrants.         

Once again team member redback earned Challenge points by finishing in the top 100 and the team finished in 26th position.

That's strange you didn't show in the results, they usually don't make errors.

Are you sure you downloaded the tasks you completed successfully after 18.00 UTC on 20 August (4am on 21 August Sydney time)? Only tasks downloaded after the challenge start time count towards the challenge score.

The next one is the most challenging of all because the Prime Sierpinski Problem (LLR) tasks will take 2-3 days to complete on my computer.
