I just wanted to reiterate the importance of having backup pools.  cgminer makes failover super easy and I actually get more shares submitted with multiple pools.  When my Pool 0 doesn't provide work fast enough, cgminer is smart enough to send a few shares to Pool 1 and then go back to the primary when it gets work.

What would be the best way to setup solo-mining as a backup? This would be helpful in case of another large scale DDOS attack that takes a bunch of pools out.

Have you tried this in 3.0.7?  I know from previous posts of solo miners (who I assume don't mine to a pool since they complained about this) that it actually doesn't show rejects like a pool because it knows they aren't shares because it knows the real difficulty target.  I wouldn't be surprised if you can still just add it to the list, but I also wouldn't be surprised if you needed to set up a pool so the target difficulty would match and the shares would get accepted (similar to how you can't mine two different chains directly from CGMiner [not merged mining], although they have different hash targets difficulty notwithstanding).

You can add solo mining as a backup in the current version as well, it just won't show any shares because there's no such thing, only block solves.

Faith....

Or debug mode if you're really concerned.

The CPU usage of cgminer is extremely low. Most of the CPU usage you see is the driver interacting with the GPU. Even in debug mode there would be no demonstrable performance hit. As for hashing, it will hash if there's something to hash and something to communicate with. It won't keep hashing randomly on any old shit just to pass the time. So if it was hashing, then it was still communicating with something, or the driver hung.

Bump.


Ok, someone said I might get 7Mhash/s more, anyone got answers to my other questions?

What messages does -quiet include?

Rejected shares?
Pool unavailable?
Not providing work fast enough?
Hardware failure?

Essentially I would like an output which has everything except accepted shares to make the logs more compact.  Is that possible?

I think -quiet also removes rejected share and "not fast enough" notifications so it is kinda too quiet.

Also what is the syntax for using -text-only and -quiet flags in configuration file.  I can get them working from commandline but trying
in config file results in parse error.  The example config file has no "valueless" configuration items so not sure what the syntax is.

I thought maybe I need a "dummy value" for the variable : value format so I tried

but I got a different parse error (invalid value for text-only).  

DOH.   

Thx.

Can the MSI Afterburner and ATI CCC be uninstalled from and Windoze XP mining systems since I'm using CG Miner for the clocking?
Thanks,

I find with GPUz running my GPU load drops to 70%
that with 3 5970's on one machine.
