I currently have about 15 spare PC's hanging around, in was just wondering would it be worth trying to cluster them with a live cd like clusterknoppix for CPU mining? Or would it be better to just miner on all of them separately?
Hopefully someone with more experience will post on this. Until then, here is my none experience take.
You do not need to cluster them. If they are running, then you will have 15 bitcoin clients running at what speed they can do.
e.g., If one is running at 1 Mhash/s and another at 4 Mhash/s, then you are running at 5 Mhash/s.
The problems that I see:
Even with 15 machines, 1 GPU will out produce them (i.e., run more Mhash/s).
The current BitCoin client will not allow CPU mining (you will have to use an old version).
Could be wrong.
Anyone confirm or deny?
