hi. 9.4.1 does not work because the pool code is changed?
No, because difficulty changed Smiley
With target=11 9.4.1 can work, but produce 4-5% invalid shares.

1 10ch = 10 9ch = 100 8ch = 1000 7ch.
Pools use PPLNS system, share cost depends on block value and total shares for last 1.5 hours.

you can do better, much better.
your compiled kernel is too big, it should be around 1193KB for better results.
how did you do it?

Why does wiki say that there is 19 Cunningham chain? We mine primecoin for several years and only find the 15 chain?

Primecoin searches a much more big primes, now minimal length is 320 bit.. it not so easy.

In addition to being much bigger, the primes mined by primecoin have special limitation (the base prime origin must be divisible by block header hash) instead of any random number. I believe this makes the mining more complex and harder to find longer chains.

Hi eXtremal
Could you add a backup server and failover functions in the new version?
xpmforall has only one address.
Sometimes it disconnects all my miners. Sometimes i get a very high latency
