You can also check out
Awesome Miner, that can manage and monitor multiple miners.
Awesome Miner has full support for the popular Sgminer GPU mining software, making it possible to use concept like device profiles, to make it much easier to configure and get started with the mining. You can also access preconfigured settings for several of the popular multi-pools from the
Awesome Miner Web Site, making it even easier to get started.
Many users also find the feature Awesome Profit Switcher useful. Awesome Profit Switching makes it possible to get higher profits than any of the auto-switching multi-pools alone, by automatically switching between multiple algorithms and multiple multi-pools.
