Phi2 miner for AMD

[ABurningSTD]

Anyone working on, or have plans to work on, a Phi2 miner for AMD gpus? There is a version of ccminer and cryptodredge for NVidia and there are supposedly attempts to get SGMiner working but no timeline. Anyone else aware of anything in the works?

Also...this is mainly regarding  https://luxcore.io

Any input appreciated!

I think you should ask the AMD Lyra2z miner  tdxminer  devs, because lyra2 2nd kernel takes 75%+ GPU time on PHI2 algo so again it should be faster on AMD vs Nvidia.

sorry, wrong discussion

phi algo is so tight on nvidias, there is no needs to do an phi amd miner. Like neo miner. It exist, but not many people use this

So far all I have to go on is whattomine estimates. Does two rigs of 1070s produce more than same number of 580s? According to 1612 #s yes, comes out to about 165 vs 200.

So if you're in it for efficiency then sure, AMD not a viable option. But realize some are playing the gamble in hopes it increases in the future. If someone can still cover costs, even make a miniscule profit, but achieve the goal of banking some coin cheaper than buying...then it's worth it to them based on their strategy. Looking at the future potential of what is mined, not the current going rate.

That said--i can't buy the "there's no need" line. There's hash to give and Dev fee to be had if someone produces something, that's the bottom line.

[ABurningSTD]

The other half of this--Phi2 isn't Phi1612. If someone gets one working, tunes, analyzes, and has the data to say "ain't gonna happen"...that's different, that's acceptable. At that point there's no choice but to move on.

it's more than simply an algorithm change, the blockheader has also jumped from 80 bytes to 144 with the addition of two fields.. thats a big cubehash512

Bumping and hoping for any news, any real input appreciated. Thx all.

nothing new to report, lux devs have been busy to get the chain back on track...

I also believe they are hoping the AMD miner will come from a 3rd party like sgminer. I don't think any of the Lux team are personally working on it - I may be wrong, but that is what I was getting from their discord channel.

[ABurningSTD]

Correct afaik. Hope here was there's be some other enterprising Dev working on something. I.E. a Claymore or other.

[ABurningSTD]

The most recent I saw in Disc:

"The people (plural) who were offered a bounty to produce a phi2 sgminer failed to do so. As I said before, it's beyond the Lux team's purview. Not much we can do about it except hope another sgminer dev steps forward."

With that...back to hoping some enterprising mind steps up...

I made an AMD miner for PHI2 based on sgminer: https://github.com/fancyIX/sgminer-phi2-branch

I did this just for fun. It may have bugs so don't expect too much on it.

My rig has 6 RX 580 at 1170 Mhz and the hashrate is about 4.5 Mhs.

4.5mh each card or total??

Im guessing total, if not two 580 is performing like a 1080 ti With a miner made for fun that would be very impressive on a Nvidia friendly algo!

Yeah, total 4.5mhs.

tdxminer is very good at lyra2z, so if they can work on this the result should be very impressive with amd cards, even better than nvidia.
Anyone has knowledge of GCN ASM may be interested on optimizing this miner.

May be lux dev can ask zawawa
