Re: Official CGMINER thread - CPU/GPU miner in C for linux/windows/osx
It is really stupid regardless of whether you are on Linux or Windows to have to run multiple instances. Especially since Cgminer is already set up to use all GPU's with one worker and display stats on one screen. Why would you want to have multiple screens that you have to toggle just to get stats.
Well, on Windows and even on Linux, there is this neat trick that allows you to resize windows and fit them all on one screen, it's quite amazing frankly.. 
Windows CPU usage can be reduced using affinity so I'm not worried about that.
Then why worry about running 3 extra processes?Given how Cgminer seems to work now, I would think (but I do not know) it would be easy to add another cmd line option to use different login names per GPU.
Load balancing / failover, pool connections, work and login data are currently shared among one process and all GPU's enabled for that process. The command line arguments would have to be extended and the logic further complicated to detect if you are loading data for one GPU and/or multiple GPU's, for those that want to pass all this info via command-line instead of configuration files, etc... If con were to add what you ask, he would have to split all of this logic off on a per-GPU level, adding extra complexity to the miner, for something that is basically a moot point. This is probably just the tip of the iceberg. If you really want this, I'd suggest starting out with a donation. Well it will take some time to add the code so by all means it should not be done. BS logic IMO.
I am not going to donate for software I deem unusable to me at this time. When it will replace Guiminer for me (Everything on one screen and ability to use a separate login per GPU) then I will start using it and certainly donate.
It is only a moot point to you because you probably would not use the feature, but do not seem to give a crap that other people will.
Yes the windows can all be re-sized but try doing that at 1024x768 with 4 windows. You will not be able to see all the windows contents without moving them.
Please don't throw tantrums. It's unbecoming of any member and is a lot less likely to get ANYONE to work with you regardless of how good an idea may be. As I said, while it would be easy to modify the command options to accept such a command, modifying the cgminer software itself to submit results on a per-username basis would take a lot longer. Honestly, with the most recent Windows ATI driver (11.8 at the time of writing), the efficiency won't drop as much as most people think because it doesn't use as much CPU/memory as the previous driver versions. Most people haven't realized this yet as they probably haven't downloaded the most recent driver. Now, you will have some more memory usage due to the extra threads of running 3 other instances of cgminer; but that can't be helped until some pretty big modifications to the cgminer code could be completed.
So please try to understand that it's not as easy as just typing in a few words and being done with it. Okay?
No worries. I seem to be the only one that wants to be able to use a separate login for each GPU anyway. The author does not seem to give a shit, nor do users of cgminer. So I have given up on cgminer and moved on.
Obviously for Windows users that do not want to toggle between multiple windows running at 1024 x 768 this is not for you if; you want to be able to see on your pool's website which computer/GPU is having issues. Stick with Guiminer or whatever you were using.
