Will NeoScrypt GPU mining be developed AMD 15.12 Drivers?
-
Hi,
NeoScrypt (and thus Feathercoin) mining broken in Windows sgminer with latest AMD Drivers (Crimson 15.12). Even if one includes amdocl.dll from previous AMD Driver version, mining is still broken. This is bad for Feathercoin. Will Feathercoin developers hire a developer to fix sgminer NeoScrypt kernel to be compatible with newer AMD Drivers?

I think @wrapper did some research, what is working and which combination of driver and sgminer versions don’t work.
Questions I have upfront are:
- is scrypt based mining possible with the latest AMD drivers?
- did you use a pre-compiled binary, or did you also try to compile on the system with the latest windows drivers?
-
ad 1. Why is Scryt even related to this? Scrypt is ASIC, nobody cares about Scrypt on GPUs.
ad 2. Nothing works, not the pre-compiled bins neither if you try to compile with latest drivers.
This is a major flaw for Feathercoin.

@Wellenreiter please contact us to [email protected] … we might have a solution for NeoScrypt issue if we can work together. Thanks.

Hi Nice Hash, you have a superb site.
I / we have only recently moved to mining exclusively on Linux, up until then the official windows version worked no problem.
Can you answer the questions?
The Reason Wellenreiter asked you if scrypt worked is that information would help us eliminate some common causes of problems. Apart from the algorithm itself, the operating code was essentially, the same as Litecoin and similar to Bitcoin. If you couldn’t operate those it indicates a problem with (such as) compatibility with a windows or driver update?
Sorry I couldn’t get straight back to you, as I was away for xmus, but will try to help.
I’ve changed the post title, as it isn’t broken, it isn’t tested or developed for comparability with the new AMD GPUS and 15.04 drivers. I have already posted that we are liable to miss those out and go straight for crypto accelerator technology, or such, and that might be a better long term investment, in my opinion.
From my perspective, FTC is an open source project and although members have spent several thousand pounds of their own cash in the past to make closed developer work “public” and “open”, particularly for the GPU kernel, that may not mean mining can be compatible with every GPU and retain a “free” project.

OK, here is little help from us (the NiceHash.com team): we just released a new version of our NiceHash Miner, which also includes extremely highly optimized sgminer NeoScrypt version. This version is also tested on all new versions of AMD Drivers. So hopefully by using this sgminer (see …\bin\sgminer-5.2.1-general in the NiceHash Miner package) will help to secure Feathercoin and NeoScrypt mining.

Sounds great, I’ll be interested how the new cards perform… epic…

Methinks they have bought Wolf0’s private kernel: http://pastebin.com/mfHUZ6bh
There is a lot of dead code used for testing, though his parallelisation of Salsa and BLAKE2s looks good.

So we have 2 new versions of miners independently developed at the same time. Yes, FTC is dead, definitely :D

My two cents on any AMD driver x such that 15.7 > x < 16.1 is TERRIBLE for mining (and probably ANYTHING except gaming.) It might be okay with certain algos, I don’t know, but the ones I tried? The OpenCL compiler just butchered them. Using bin files or GCN assembly to generate your own bin files should be okay. 16.x I haven’t evaluated yet.
