OpenCL component for mining


#1

Hello everyone,

I’m wondering what the current state of mining on testnet for AMD cards. I’ve done a little research into GrinGoldMiner and Grinminer, but I can’t seem to find any open-source contributions towards testnet-4 for OpenCL. Is there anyone working on the latest PoW for it?

We would like to launch with Grin as one of our coins @ coinmine.com. If there is work that needs to be done to help, we’d love to hear about it!

I believe @photon and @hashmap are working on one right now. They might need some help.

Nice product by the way. I’d get one if I actually had an address.

Correct, @photon has implemented the hardest part - an initial version of lean trimmer https://github.com/mozkomor/GrinGoldMiner/tree/master/src/ocl_cuckatoo_lean_mini I work on wrapping it into Rust and adding cycle finder https://github.com/yourowncrypto/ocl . It’s just a start, a lot to be done.

Any help is appreciated.

Cuckaroo PoW won’t work well on a 4GB card. Cuckatoo ASIC PoW could, but won’t mine nearly as much grin.

Thank you for the quick replies!

We’d love you to have a Coinmine. We know you have no address and Opsec issues, but if theres anyway we could get you one, feel free to drop us a note at support@coinmine.com.

@hashmap
I know a little Rust, so I’ll check it out tonight. It is our understanding that mean mining is the best way to mine Grin? Is there any progress/way we could help with that?

@photon
We’ve done and are doing more research into the hardware requirements and are considering our options as far as GPUs and memory regarding the reduced performance.


#7

You can only mean mine cuckaroo GPU friendly pow (8GB). And with cuckatoo32 you can only lean mine (1GB) unless you use 32GB card to mean it.

@coinmine you can contribute directly, the code is open source. also if you could provide us with ssh access to linux box with amd card it would be great, so far I only test on Nvidia and Apple OpenCL platforms.


#9

Okay, so I’ve been watching the videos from grincon0! Very awesome!

@hashmap if I can, I’ll try to get an open ubuntu box with an AMD 8GB GPU that you can use sometime next week.

@coinmine here is the initial version of lean cuckatoo solver made by @photon (I just wrote a rust wrapper on top) https://github.com/cyclefortytwo/iron_cuckatoo. I hope to integrate it into the stock miner soon.

I tested IRON Cuckatoo. Builds and works @ latest Ubuntu and 1080 TI.
