One less item on my to-do list for this weekend now that you've released a GPU based miner. Grin

Sorry if I missed something, but how do you configure the miner to run on testnet? I received too many stale submissions followed by the miner hanging. Please see the log file below:

CPU: AMD FX-8350
GPU: AMD R9 280X

This seems to be normal for an optimized miner.

The miner does not stop mining the sieve until the original one is verified by a slow mpz_nextprime() call. When your miner is significantly faster than the PoW function you tend to find lots of shares before the PoW can stop the sieve from mining.

Regards,
