not working with the parameters posted.
RX580 windows 10, adrenaline 18.3.4 drivers in compute mode. tried it on my test system with a single 580 in it.
i get a switching to devpool at startup, and then sgminer errors out.
I'll try again on the next version.
Try with --gpu-threads 1, some systems can't run 2 threads per GPU. Also, sometimes the miner doesn't start properly after first execution (due to first compilation), but it works as expected from there.
The miner switches to devpool at startup just to open the connection (and keeps it open), then switches back to user pool.
