Hello,

First, let me thank you about your dedicated time in BFGminer project.

I was wondering if it was possible to run multiple instance of BFGMiner on a single machine to mine different coin with different pool, both having their proper fail over pool.
(In other words, on the same machine, BFGMiner Instance 1 mine X coin on Y pool having Z fail over pool, BFGMiner Instance 2 min A coin on B pool having C fail over pool)
I'm calling BFGMiner from a batch file (if that can help) so I can configure switchs as needed.

FYI: I'm using the NanoFury USB chip only (for the fun of it)

1- I've tried the -d and / or --device switch to turn off some of the devices on instance 1 of BFGMiner and enable them on a second instance
Result -> First instance still showed all the USB device even those NFY that were turned OFF. Second instance -> ran but detect no device

2- I've also tried the -S switch to scan device and try to "separate" them from the command line, wasn't successful.
3- I thought using the --set switch to set default parameters on the wanted NFY on each instance but didn't succeeded.
4- I've also tried to "release" a NFY chip when BFGMiner was running but it only turned it OFF

Is it possible to run BFGMiner like I was trying to do, is it a configuration issue or that particular scenario isn't supported?
Thank you

It might not be recommended but I run three different instances of BFGMiner on the same machine:

3.2.1 for Block Erupters
3.5.1 for Blue Furies
3.10.0 for Antminer U1's

It works very well and allows me to power down all the Blue Furies when one inevitably hangs while leaving the other miner types running without interruption. I run the Blue Furies and the Antminers in the same hubs, works fine. I used to run all three types of miners in the same hubs but there was some complication which caused a conflict between the Antminers and the Block Erupters although I'm pretty sure that if I had burned my brain some more I could have resolved what I think was a conflict generated by the command line on the miners.

It's going to be fun as I'll be endeavouring to add some DualMiners into the mix which are being shipped as we speak, although I'm not sure that they'll be supported yet by BFGMiner so I might have to run some other miner for a while but you can bet that I'll be switching to BFG when the DualMiners are supported, so that will probably be a fourth instance of BFG running on the one machine.

Good luck with it.
