I 'm getting this:
Searching for pattern: "1BETBTCcom" Reward: 0.200000 Value: 0.000000 BTC/Gkey
Difficulty: 2938077882634386
Total value for current work: 0.000000 BTC/Gkey
[22.68 Mkey/s][total 48909778944][Prob 0.0%][50% in 2.8y]
- Is "no version information available" is just a warning or a serious error?
- Does the miner search only for the displayed pattern (ie 1BETBTCcom) or a pattern set?
- Can we use several miners (different computers) with the same credit address?
No version info available is just a warning; as you can see, it does searches for the hash regardless.
The miner only searches for the one pattern displayed (it choses the one it thinks being most profitable based on reward divided by difficulty).
You can use as many computers with the same credit address as you want; if one of them finds a solution it will submit it with that address. The computations are done "offline" with no shares sent to the upstream server, so it doesn't really knows how many miners are there until one of them finds a solution. (Well, technically they still request a list of available bounties from the server every once in a while, but it gives no indication to the pool of the speed and capacity of each client).
