I ramped up too late but I didn't know we were in it until a few hours after it started and I have only been all out for 24 hours. If I would have got enough tasks for the whole challenge in the first day it would be a different story. I am now up to 1400 tasks pending.
Oh well, I always wanted to see what I could do on Einstein and this gave me a good excuse. I'll be back to gpu grid and NFS for the rest of that challenge this afternoon.
