Assign sgminer to specific gpu

[Coin_Joiner]

Hi all,

i've been mining with SGMiner 5.5.5 for a short time now and everything works well enough. Now i'm looking to place a second gpu into my system, but i want that gpu to mine to a different wallet (same algo). Why? Simple: one device belongs to me and the second one to someone else. Power cost offsets investing into a new platform, so power consumption is not a issue.


I have found a device "switch" wich you can add to the config file, but i'm wondering if this will work. It looks like this:

"profiles":
    [
        {
            "name": "xmr",
            "algorithm": "cryptonight",
            "rawintensity": "1000",
            "worksize": "8",
            "gpu-threads": "1"
            "devices": "0 or 1"

The last line should specify which device should be used. In the first config file I would use "0" and in a second file I would use "1". Is this the correct why to approach this or is there another way?

you can try this in same config file :

          

Code:

"profiles":
    [
        {
            "name": "xmr",
            "algorithm": "cryptonight",
            "rawintensity": "1000",
            "worksize": "8",
            "url": "stratum+tcp://<my_pool>",
            "gpu-threads": "1"
        }
    ]  
"pools":
 [
    {
      "profiles": "xmr",
      "name": "xmr-me",
      "user": "<my_wallet>",
      "pass": "x",
      "devices": "0"
    },
    {
      "profiles": "xmr",
       "name": "xmr-my_friend",
      "user": "<my_friend_wallet>",
      "pass": "x",
      "devices": "1"
    }

  ]

or use "quota" :

Code:

"profiles":
    [
        {
            "name": "xmr",
            "algorithm": "cryptonight",
            "rawintensity": "1000",
            "worksize": "8",
            "gpu-threads": "1",
            "load-balance": true,
        }
    ]  
"pools":
 [
    {
      "profiles": "xmr",
      "name": "xmr-me",
      "user": "<my_wallet>",
      "pass": "x",
      "quota": "50;stratum+tcp://<my_pool>"
    },
    {
      "profiles": "xmr",
       "name": "xmr-my_friend",
      "user": "<my_friend_wallet>",
      "pass": "x",
      "quota": "50;stratum+tcp://<my_same_or_other_pool>"
    }

not sure for all but you can try

This is an even more elegant solution then using two config files. Nice! I will give it a try! My only concern is that the two GPU's are different (a RX580 and a R9 270X). The raw intensity and worksize variables might cause problems. I'm currently using 1000 and 8 as values for raw intensity and worksize for the RX580 gpu. This works fine. Since the 270x is an older card these values need to be adjusted. What kind of values would you recommend?
