Avermore miner - optimized sgminer (AMD) fork for x16r/x16s/xevan(beta)

[parishy]

 
Hi everyone,

This is my first time making a post here, but some of you may know me as the developer of Nevermore miner for x16r / x16s, and creator of one of the first sgminer forks for x16r. I recently had a generous person donate a RX580 to me, and thus was able to give the AMD side some love by making some x16r optimizations for AMD.

After around a week of work, I've made numerous optimizations to the x16r / x16s kernels, and with preliminary testing I'm getting around +20-25% over ace's sgminer (the previous fastest x16r miner).

x16r / x16s average hashrates:
RX580: 8.3 MH/s
Vega56: 13-14 MH/s
Vega64: 14-15 MH/s

xevan hashrates (still in beta; doesn't work with all cards yet):
RX580: 1.8-2.1 MH/s, depending on OC
Vega: N/A (HW errors)

As with Nevermore (which is for Nvidia cards), Avermore (for AMD) has a 1% devfee to support continued work on the miner.

I look forward to hearing your feedback about this new release.
