YiiMP now allow users to share their ccminer (1.7.6+) device hashrate, more supported miners will come later.

-o stratum+tcp://:<PORT> -a <algo> -u <wallet_adress> -p stats

You can download the compatible version of ccminer here :

• http://ccminer.org/preview/ccminer.exe (x86 CUDA 6.5)
• http://ccminer.org/preview/ccminer-x64.exe (x64 CUDA 7.5)

With this option enabled, the stratum will ask for device stats each 50 shares (for 4 times max).

You can combine this miner option with other ones, like the pool difficulty with a comma.
