It is not. You will lose the clients if you do that and you will be the cheater by changing the rules at the middle of a challenge when people already wasted energy by crunching your project.

And this is considered normal strategy? I'll not touch WUs which were already sent, but I've restricted the number of WUs in progress even more: 1 WU per CPU core + 10 WUs per GPU. I don't want it to be worse  server might not sustain this wave of submissions once the challenge starts.

Don't make restrictions yet. Let the challenge end first.

P.S. CPU restriction (2 tasks per CPU core) has always been there, and I only added GPU restriction yesterday (10 tasks per GPU). I guess everyone concerned took their tasks before that. P.P.S. I thought again and increased limits for now: 4 tasks per CPU core and 100 tasks per GPU. Since this tactics is already used, these limits will be fair for late joiners. 4 tasks per CPU core is ~24 hours of work for average CPU and 100 tasks per GPU is ~8 hours of work even for GTX 1080.

Big congratulations on reaching this limit, doesn't seem that long ago we were finding 14 and 15 digit pairs! Do you have any estimates on how long getting to 20d will take? That will be a big milestone. Over the last few week my gaussian
amicable seach has been a lot more fruitful, I'll post an update soon and hopefully it will reach 400 pairs or close to this! Andrew Last fiddled with by AndrewWalker on 20170822 at 09:01
