LTC GPU Miner Source Code Reward Thread

[tacotime]

Hey,

I want to offer 500LTC to the first person to give the source code for an LTC GPU miner.  The code must be compilable on nVidia and AMD GPUs.

I wanted to start this thread to get other people involved too.  I think it may motivate ssvb to finish his miner quicker and release to the public if everyone is willing to pitch in some.  So, if you want to pitch some money into this too, let the people out there who are working on LTC miners know with some offers.

When the GPU miner is released I'll put the authors LTC address on here so you can offer your coin up to them.

2nd edit:

Coblee has set up a reward address.  Please forward all donations to this LTC address:

Code:

LgpuY1d6ncPkN9XYVGWraiohJXTqSKdqtL

Current reward: http://abe.liteco.in/address/LgpuY1d6ncPkN9XYVGWraiohJXTqSKdqtL

Or for BTC:

Code:

Current reward: http://blockexplorer.com/address/1gpuEVUaML1pXEUNVeREnQqitfv1DeUMD

edit: I may as well keep track of people willing to donate here too.

I'd tip some bitcoin or litecoin for an open/working miner.

I would suggest coblee to make a wallet for donations,so all money would go to the first person who would release open source GPU miner with reasonable performance.At least 150khash\s for hd5850

I second that. As I said before, I'm willing to donate 10 BTC for a Litecoin open source GPU miner.

[tatsuchan]

I'll donate if this gets set up.

I used vanitygen to generate this address: LgpuY1d6ncPkN9XYVGWraiohJXTqSKdqtL
Please send your donations there. I will send the private key to the the person that delivers the source code.

That seems to be a Litecoin address. Can we have a Bitcoin address too?

I'm very much wondering if the Reaper miner for LTC is just a simple permutation of the regular Reaper miner... It doesn't look like it'd be very hard to port to LTC if someone had a day or two on their hands to dedicate to this, but I don't have time to play around with it.

http://solidcointalk.org/topic/425-reaper-v12-a-standalone-cpu-gpu-miner/

AppOpenCL.cpp/.h : Port the memory mappings to those required for LTC.
reaper_????.cl : Port the scrypt.c hash code to CL ( https://github.com/pooler/cpuminer )
RSHash.cpp/.h : Port this from scrypt.c as well, for checking the block hash on work done by GPU.  Reaper includes the genesis hash and related functions, but I'm not sure the miner uses it.

Sent 500LTC from one of my wallets...  That's about 1600LTC there now and 10BTC.

Nope, it crashes with nVidia for me on either OS

edit:
also, these curious functions

void shittify(uint4 B[8])

How did you get it to compile?

What I did:

In the cmake list (CMakeLists.txt) remove everything reference cl libraries and place the cl.h/cl.hpp/other files wanted in the directory
Change import <CL/cl.h> to "cl.h" in the AppOpenCL.h
Tweak any other weird errors you get, I think one of the files is missing "include <math.h>"
Compile with the cmake script included
Then try to make the cl kernel compilable, that's where I'm at.  Can not get it to compile on nVidia at all though.
