Title: Mine Litecoin and Novacoin at the same time cgminer Post by: giantjoezilla on May 22, 2013, 04:42:27 AM This might be a stupid question, but I was just wondering if its possible to mine both coins at the same time. I know that you can set multiple pools in cgminer, and both Litecoin and Novacoin use scrypt. So I was wondering if I set 2 mining pools, one Litecoin and the other Novacoin, if I could mine both?
Title: Re: Mine Litecoin and Novacoin at the same time cgminer Post by: Bakemono on May 22, 2013, 06:31:48 AM Multiple pools are for the case a pool fails(gets offline or something) your miner switches to the next pool.
It is not for mining at two pools at the same time. Title: Re: Mine Litecoin and Novacoin at the same time cgminer Post by: giantjoezilla on May 22, 2013, 06:53:24 AM from the cgminer readme
MULTIPOOL FAILOVER STRATEGIES WITH MULTIPOOL: A number of different strategies for dealing with multipool setups are available. Each has their advantages and disadvantages so multiple strategies are available by user choice, as per the following list: FAILOVER: The default strategy is failover. This means that if you input a number of pools, it will try to use them as a priority list, moving away from the 1st to the 2nd, 2nd to 3rd and so on. If any of the earlier pools recover, it will move back to the higher priority ones. ROUND ROBIN: This strategy only moves from one pool to the next when the current one falls idle and makes no attempt to move otherwise. ROTATE: This strategy moves at user-defined intervals from one active pool to the next, skipping pools that are idle. LOAD BALANCE: This strategy sends work to all the pools to maintain optimum load. The most efficient pools will tend to get a lot more shares. If any pool falls idle, the rest will tend to take up the slack keeping the miner busy. BALANCE: This strategy monitors the amount of difficulty 1 shares solved for each pool and uses it to try to end up doing the same amount of work for all pools. So you can mine multiple pools.

The answer to your original question about mining Litecoin + Novacoin is no, unfortunately. While you can mine at multiple pools by balancing your submitted shares between them (assuming the pools are all for the same coin, i.e. Litecoin), you will not be mining at full speed at both of the pools as you're essentially splitting your hashing power between them. The ability to specify more than one pool in cgminer is primarily for failover situations (as Bakemono described) where your miner will automatically submit shares to a backup pool if your preferred pool goes offline for whatever reason. Mining two different coins simultaneously, as in your Litecoin + Novacoin example is what would be known as merged mining and is currently not possible for any of the scrypt-based coins (Litecoin, Novacoin, Feathercoin, Worldcoin, etc). Where merged mining is possible, i.e. Bitcoin + Namecoin, it's implemented on the pool side and does not require special configuration of cgminer.

Is it really possible to mix pools for different coins? I know that you can e.g. solo-mine in cgminer and leech the new block info from a pool. But that would assume that the pool config in cgminer refers to a single coin! Otherwise the new block info is bogus. Does anyone know whether this is a problem and if so how to get around it?

Otherwise the new block info is bogus. Does anyone know whether this is a problem and if so how to get around it? I think you're right. As you described, the behavior wherein cgminer uses stratum/longpoll notifications from backup pools would cause cgminer to erroneously think that blocks have changed over when they haven't. I don't see any way to disable this behavior and in the very start of the cgminer readme there is the message "Do not use on multiple block chains at the same time!" which seems to be an acknowledgement of such issues.

Ever since I stopped mining bitcoin, I've missed getting those extra namecoins. |
