I got it running loooong time ago but I had to wait for the .4 version. It did a pretty good job until I stopped mining because buying the coin made more sense than mining. That was in April or May 2012.
Now, because cgminer is faster and way better written and has lots of good features, I moved to cgminer last week.

Topic: PSA : Final Litecoin LTC GPU miner released !!! (Read 25975 times)
I couldnt make reaper working. I tried to run cpu-only mining litecoins only and it told me that a config was missing about threads per cpu. I added the config and then it told me that litecoins cant be mined with reaper. oO Then i used the normal exe and it had the error that it cant connect to OpenCL. I have a NVidia GeForce 9600M GT and i can mine bitcoins with it by using guiminer. So i think everything needed is installed.
Whats the problem there and how to solve?
Thanks!

Hi guys
Do you know what the best config for LTC mining is for this card:
Nvidia GT330M on a MBP booted into Win 7 (via bootcamp)?
As I've been trying to get reaper to work on as many computers as I can to mine for me.CPU mining works well on there.I get around 25KH/s from it's CPU (Core i7 620m) and now I want to tap into the GPU simultaneously.Which settings reduce GPU use so I can still have a responsive desktop without my MBP freezing and screen turning black whenever any GPU intensive app is run?
All help is appreciated.

I've tried just about everything and I've gotten errors compiling, decided to work just via cpu mining and then I get errors saying the config file (which I specified) was not found. >___> Someone needs to come up with a start to finish tutorial. I've been able to get every single other miner to work with a little work, but this one is just a tough nut to crack.
You need reaper.conf and litecoin.conf and if you plan to mine BTC and SLC, you also need bitcoin.conf and solidcoin.conf.
Default config files are in /reaperv13b/ and not in /reaperv13b/build/
cp your executable 'reaper' from 'build' ../ and edit coin specific files.
./reaper.conf looks like this (I deleted 2lines, "mine bitcoin" and "mine solidcoin")
Code:
kernel reaper.cl
save_binaries yes
device 0
enable_graceful_shutdown no
long_polling yes
mine litecoin
platform 1
./litecoin.conf looks like this:
Code:
host put_your_host_here
port 9332
user username_here
pass passwd_here
protocol litecoin
worksize 528
aggression 14
threads_per_gpu 1
sharethreads 18
lookup_gap 8
gpu_thread_concurrency 6144
platform 1
long_polling yes

How do you install this from source on Ubuntu 
Got to this. Any help
~/Documents/reaper/build$ cmake reaper
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

I think that means you don't have the AMD APP SDK installed. Get it here:

I was going to use a Nvidia 8500GT which only has Cuda compute compatibility 1.1 will it work?

oh ... so is LTC CPU mining as good as dead now?...
No dead, but not so much block shares on pool because of gpu people take most. I have 3 6970 mining litecoin near 1.3Mhash/S making close 1000 LTC na day.
Go solo mine you cowards!
I am making around 500LTC per day which is more then what mining calculator predicts according to my hashrate.

I just stop all my Litecoin mining rigs... Litecoin loses its meanings...
Well if litecoin does become worth more you will likely kick yourself thinking why didnt I keep mining......I did that with namecoin when it first came out. I mined it then stopped because I didnt know if it would amount to anything. Of course it ended up hitting $2.50 per coin in June of 2011.

I get about 520 kH/s out of my 5970 for a few seconds, and then I get nothing but "Weird response from server" or something like that. I don't get what I'm doing wrong 
Your fine, I assume its caused by lack of longpolling, just let it run, and eventually the shares submit.

I cant, for the life of me get this working. Stupid reaper just keeps saying
"Error: Config file .conf not found."
"Error: Config file .conf not found."
I kept getting that until I put all the config options in one file, called "lightcoin.conf", and invoked Reaper as "reaper.exe lightcoin.conf". Then it loaded the same file twice, but seemed perfectly happy about it and ran just fine.
Side note, on the off chance mtrlt peruses this thread...
I've poked a bit at the .cl file for Lightcoin support in Reaper, and although I have a few questions (like what the hell the gpu_thread_concurrency and lookup_gap "mean", aside from their role in memory block alignment), I have one "real" question...
Why does padcache (aka lookup in scrypt_core()) use workitem-major order (ignoring z) rather than y-major order which (for non-CL C code) would better preserve locality of reference? I refer to the output of the coord() macro here. I honestly don't know if it makes any difference in performance given the overall pattern of memory access, but I wondered if on some cards that serves to improve vector performance (by using the dot product rather than a straight mult)?
