fastest linux open source zcash miner: 36 sols/s on R9 380

[nerdralph]

I optimized Marc's silentarmy kernel, getting a performance boost of about 15%.  Kernel memory use is also tuned to allow 2 threads on 2GB cards.
Linux binary is included for Ubuntu/fglrx.  Likely requires a fresh build if you are using AMDGPU-Pro drivers instead of fglrx.

I get 35-36 sol/s with a R9 380, and 30-31sols/s with a R7 370.

Sounds very interesting.

Are the R7 370 cards you tested 2gb or 4gb?


on silentarmy v3 I can only run 1 instance (~1.3gb) per R7 370 2GB model

So this is just for Tonga and Pitcairn?

Works great on Hawaii too.  My 290x clocked at 1000/1250 gets 41-43 sols.

Nice I will give it a try and see what numbers I get.

You can run a mining pool but you can't extract and run files from a compressed tar archive?

bazinga!

Thanks, seems it's a better hash rate on NANO cards:

Code:

Total 136.9 sol/s [dev0 47.4, dev1 46.0, dev2 46.0] 9078 shares

[smaxz]

most impressive 7950 rates also. mucho thanks

YUP - Thanks for sharing!!!
I'd trying it now with my (3) RX480 4GB cards.

[nerdralph]

Just tested Claymore's Linux miner, and it is ~5% faster.  Therefore I've changed the title to fastest open source miner.
I think I can get another 15-20% improvement in performance out of the silentarmy kernel, and claim back the title to fastest overall.

Thank you.

Here my rigs results: Ubuntu 14.04 headless with AMD 15.x GPU drivers.
3 280x and one 270 GPUs.

it started slow but steady around 72 sols.

Did someone try this kernel on https://zec.suprnova.cc yet?

I got an error with this fork:

Stratum: invalid msg from server: type object 'bytes' has no attibute 'hex': {'result': True, 'id': 2, 'error': None}

The normal v3 works fine. Maybe try to re base your fork off the latest mbevand? He has removed the libsodium dependency too.

just update python to 3.5-3.6.

Just tested Claymore's Linux miner, and it is ~5% faster.  Therefore I've changed the title to fastest open source miner.
I think I can get another 15-20% improvement in performance out of the silentarmy kernel, and claim back the title to fastest overall.

do that while keeping it open source and "fee less" and i pledge i will donate .05 ZEC to the address of your choosing.

cheers

I'm python-clueless. Thanks it worked!

41-47H/s on a 290 -- the standard version was only getting 36-42.

[Eliovp]

Even though Claymore released a linux version, this one is still faster.

Yeah, you have to kind of know what you're doing to use this, although that it's still super easy to run/compile..

I do plan to pull down Marc's changes at some point, but right now I'm focused on tweaking the kernel.

We'll see.  Based on JW's experience with ethminer, donations were much less than 1% of mining revenue even before Claymore release his miner.  Right now my thought is to have an open-source version that is as fast as Claymore's and one that is at least 10% faster for a private miner.
